4Sevens Quark QTA - Initial Impressions

[NH Shooter]

I had been looking for a smaller alternative to a 2-CR123 light for EDC. While the Surefire light I would clip in my pocket when venturing out at night is extremely capable and trustworthy, it is a little too large to use as a true24/7 EDC.

In my search for a smaller light, here were my primary requirements;


Single-cell battery to keep OAL as short as possible
A minimum of 200 lumens maximum output
Simple UI with a “tactically correct” forward-clicky tail cap
Well-secured clip for deep-pocket carry
Durable construction



Since I already own several Surefire lights and am familiar with their high quality and robust construction, an EB1 Backup was my first choice but was out of the price range I wanted to spend on an EDC light that would have a higher probability of getting lost or stolen. After much research, I found the perfect fit for what I was looking for – the 4Sevens Quark Tactical QTA (http://www.foursevens.com/products/QTA-AE).

The QTA is a single AA battery light, with a rated maximum output of 130 lumens with a 1.5 volt alkaline battery. The light had been near the top of my list and I was ready to order the Quark Tactical QTL (http://www.foursevens.com/products/QTL-AE), the CR123 version of the light (which has a maximum output of 246 lumens) but the idea of being able to use the commonly-available AA battery kept me intrigued.

The breakthrough came upon the following two discoveries;


The head used with the AA-cell QTA is the same head (http://www.foursevens.com/products/UQA4) used with the CR123-cell QTL and is rated for .9 to 4.2 volts
The Titanium Innovations CR14505 CRAA 3V Lithium AA (http://www.batteryjunction.com/titanium-cr14505-craa--3v.html) battery, which is 3 volts and 1500mAH capacity – identical to a CR123 cell



Using the CR14505 cell in the QTA gives it the same 246 lumen capacity as the QTL but with the added benefit of being able to use standard AA alkaline batteries in a pinch. It can also use 14500 Li-ion 3.7 volt rechargeable batteries, which further increases maximum output to about 280 lumens but with only half the run time of using the CR14505 lithium cell.

With all of my main requirements met, I purchased the Quark QTA. Though I’ve only had the light for a few days, I can make the following observations;


Though as a “Surefire guy” I will remain concerned with its durability until I’ve spent some time with it, the QTA appears to be well made. All the parts fit well and the light functions as advertised. The country of origin states “Assembled in China with components from USA, China and Malaysia.”
Though the clicky-switch doesn’t have as smooth of operation as a Surefire unit, it functions perfectly. The switch requires moderate pressure and about an eighth-inch of travel to momentarily activate, and about another three-sixteenths travel to click on. Complete replacement tail caps are available from 4Sevens for $9.00, so if it wears out prematurely, replacement is a non-issue.
I very much like the UI and the fact that two modes can be programmed. I have maximum output set for when the bezel is tight against the body and the 6-lumen option for when the bezel is loosened. The bezel only has to be turned about 20 degrees to switch between high and low output. The bezel turns smoothly and can be easily turned with the thumb and index finger in one hand.
The optional deep carry pocket clip (http://www.foursevens.com/products/UQE9) is well-secured to the body. As expected, the light “disappears” into the front pocket of my jeans, both visually and comfort-wise.
The Quark series of lights are “Lego-able” meaning heads, bodies, tail caps and other accessories (http://www.foursevens.com/products/accessories/Quark&list=) are interchangeable between the various models (heads must stay within designated voltage ranges). For $20, I may end up ordering a single CR123 body (http://www.foursevens.com/products/UQB1) which would convert the QTA into a Quark Tactical QTLC (http://www.foursevens.com/products/QTLC-AE).


Performance

As expected with the Cree XP-G2 emitter, output is smooth, intense and neutral white. Compared to my SF 6PX Pro (Cree XP-G, 200 lumen version), the QTA produces a comparable corona and spill, but without the well-defined center hot spot of the Surefire. Though the 6PX has better throw due to that hot spot, the smooth and uniform corona of the QTA provides superb area lighting and is exactly what I was hoping for in an EDC light. At 246+ lumens, it retains more than sufficient reach and most certainly would temporarily blind an assailant in a self-defense situation.

EDC Use

Along with the optional deep carry clip, I fashioned a finger-loop lanyard out of paracord. The lanyard is small enough not to ruin the “pocket-ability” of the light but enables open-hand retention. With the loop around my support hand index finger, the light can be easily used in a conventional overhand grip as well as a cigar hold, making it suitable for a variety of handgun/flashlight techniques when used in conjunction with my PPS. With a flick of the wrist, the light can be swung to the back of my hand, remaining fully retained and allowing full use of the support hand. The lanyard can also be held squeezed between the index and middle fingers for open-hand retention and of course, serves as a method to retrieve the light from the pocket.

Conclusion

For under a $60 investment I am impressed with the 4Sevens Quark QTA. It truly meets my requirements for an EDC pocket light and then some. Time will tell how the light stands up to EDC but so far I am optimistic that I will remain pleased with the purchase and that the light will continue to meet my needs.

The light and optional deep carry clip was purchased from www.environmentalled.com for a total of $57.45 including USPS Priority Mail shipping.

Full specs on the Quark QTA can be found on the 4Sevens website (http://www.foursevens.com/).

NH Shooter, thank you for a very in-depth and detailed review.

I've been thinking about replacing my little old keychain-carried Four Sevens Preon Revo with a more powerful if slightly larger edition, and the QTA looks like a good choice.

[Tom Fineis]

My requirements are similar to yours and I have been happy with a couple Quark lights over the last two years as well.

I am using the 2x AA version with Eneloop rechargables. I have considered going to a 14500 setup or something else but I got a good deal on a bunch of Eneloops and I am happy with them.

I like the ability to access a low mode without getting high first, and I like to have high as a "default." The twist head accomplishes this perfectly with a simple on/off switch in the rear.

The Quarks are built well with good clips, something that is overlooked often even by top brands. All in all, I can't think of anything else I would want in an EDC light that the Quark line doesn't provide. It's one of those rare products that continues to exceed my expectations.

[Coyotesfan97]

It's always dangerous for a flashlight addict to read this forum. I just ordered a QTA off Amazon after reading your review.

[littlejerry]

I've got one of the original QTA lights that was rated for ~80 lumens. I believe I got it in 2008... Or maybe 09. I carried it every day for many years until I got the itch for more power. I bought a QT2Lx which was only 0.5 inches longer but allowed 800 lumens on burst, and much longer runtimes on lower levels.

My QTA still runs perfect and my wife caries it in her purse. Quark lights are excellent and my go-to any time I need a good pocket light.

I purchased the 2xAA turbo for my FIL a few years ago. He uses it frequently and loves it.

[Steve f]

My only issue was the size and losing it in my bear paws.... this is often over looked by many...

[runcible]

I'm unsure reading the manufacturer's description - can this be configured for single-mode activation (always clicks on to highest)?

Guys I've been using Quarks now for about 5 years and you're not gonna' find a better light for the money.

Same here. I have been carrying a Quark for about four years or so now. I have five different ones scattered between myself and my family. Every time I see a new cool light that I think will be "the one", I always end up coming back to the Quark for it's combination of features, durability, and price.

[olstyn]

+1 to all those that have said Quarks are great. I've got the QTL (CR123 version of the light reviewed here, the only other major difference being that the clip is reversed vs this one; when clipped to a pocket, it carries output end up, and not quite as deeply), and I've been using it daily and loving it for about 6 or 7 months now. For my use (a few minutes a day on the setting one down from max brightness), I tend to get about 2 months out of a charge using RCR123a batteries. The only "gripe" I might have is that the anodizing on the clip is starting to look pretty worn from banging into stuff while clipped to my pocket, but it's a tool, not a display piece, so that really doesn't matter.

[Tom Fineis]

I'm unsure reading the manufacturer's description - can this be configured for single-mode activation (always clicks on to highest)?

There are five or six modes available, and the user programs them into memory. Only two modes are accessible once programmed, and they are selected by the bezel tightness.

For instance, I have "high" programmed when the bezel is tight, and "medium" for when the bezel is loosened 1/8 turn. You then decide how to carry it by default.

I HATE lights with tailcap mode changes and I hate light that get you lost in modes, make you cycle through them to get the one you want, etc.

You can program strobe into one of the bezel settings if you want. I know some have theirs set for strobe/high.

I use mine for civilian EDC and for EMS work. Low is great for utility tasks like reading medicine bottles in dark apartments, and high is a defensive setting or searching for vehicles/patients outside.

The little things make these. Security and ease in/out of pocket is a big one. Most manufacturers of guns, lights and holsters overlook the small touches that make a big difference in day to day use.

Steve- have you tried the 2xAA body? It is just as thin but might be long enough to help with grip. I have one you can play with.

[runcible]

Thanks, SN!

This is very interesting for me for when going pretty minimalist - a knife in the strong side AIWB slot, and a light in the off-side AIWB slot. As I've yet to get good word on if the VTAC\SF lights are getting upgraded, this looks like a great alternative.

(Though I don't think I'll have the same issue as Steve.)

[NH Shooter]

For those who want a kick-butt version of 2-AA, here's what I would do;

1. Order this light, which has a maximum output of 780 lumens @ 6 volts - http://www.foursevens.com/products/QT2L-X-AF
2. Order a 2-AA body - http://www.foursevens.com/products/UQB4
3. Use either 14500 Li-ion rechargeable batteries or the TI 14505 lithium cells I linked to in the OP to get the required voltage for max output.

The only downside to this set up would be standard AA alkaline batteries will not have adequate voltage to operate the light.

Here is a 336 lumen 2-AA light that will work with any AA battery - http://www.foursevens.com/products/QT2A-X-AE

[EricM]

Nice review, and very interesting about the TI 14505, I'd never seen a 3V AA-shaped lithium primary before, guess I've been out of the loop, pretty cool! The finger-loop lanyard seems like a neat idea too.

I've been very happy with my Quarks over the years, my EDC is what's now known as the QT2L-X, I use a QT2A-X with Eneloops around the house, and my toddler has a QTA because she wanted a flashlight like Daddy's (set for now on the lowest mode!). I like the shape of the beam on the XM-L models. Just upgraded to a couple of the latest burst mode Quarks yesterday with their 30% off Cyber-Monday sale (http://www.foursevens.com/november_29_2014.html) -- looks like the code might still work even though it was supposed to end at noon.

[NH Shooter]

Nice review, and very interesting about the TI 14505, I'd never seen a 3V AA-shaped lithium primary before, guess I've been out of the loop, pretty cool!

I'm seriously thinking of buying the QT2A-X (http://www.foursevens.com/products/QT2A-X-AE ) (336 lumens using the Cree XM-L2 emitter) and swapping the XM-L2 head onto my current QTA, which would result in a 336 lumen single-AA pocket light! I would place the QTA head (Cree XP-G2 emitter) on the new 2-AA light and keep it in the car loaded with standard AA lithium (1.5 volt) batteries.

These things are addicting....

[UNK]

General rule of thumb is, when all other things are equal, a light must be twice as bright to be "noticeably" brighter, and four times brighter to appear twice as bright to the human eye.

Awesome review NH Shooter! Thanks

Dude if I were doing what you do I'd run a two cell 123 Quark.

Awesome review NH Shooter! Thanks

Thank you, and my pleasure.

I've made a modification to the "finger loop lanyard." I was concerned that if someone got hold of the light with the lanyard around my finger, they would be able to put a serious hurting on me (or at least that finger), so I replaced the Lanyard Closure Arrowhead (http://www.lighthound.com/Lanyard-Closure-ArrowHead-2-Piece_p_739.html) piece with a Lanyard Break-away Connector (http://www.lighthound.com/Lanyard-Break-Away-Connector_p_737.html). The connector is still strong enough to work as intended but will open if someone tries to use the light to gain leverage on me. I'll post a photo of the revised lanyard this weekend.

Risking going way too far into flashlight geek mode, I have some parts on order to build another QTA "lego style." It will use the Tactical Quark Turbo head (800 lumens max) in combination with a single high current AW 14500 LiMn battery. If you look at post #13 in this thread (http://www.candlepowerforums.com/vb/showthread.php?368020-Foursevens-Quark-Tactical-QT2L-X-Burst-Mode-review), you will see a run time/output chart for this configuration; 750 lumens to start, tapering down to 420 lumens after 2 minutes and holding that output for another 22 minutes before depleting the battery. That's some serious light in a small package.

Here is the list of parts needed to build this pocket-sized blaster;

http://www.lighthound.com/AW-IMR-14500-LiMN-Rechargeable-Lithium-Battery_p_3644.html

Of course, a charger is needed for the LiMN battery as well.

[UNK]

So what is the benefit of higher lumens? If it was a thrower I could understand. But as a flood I don't understand the benefit.

So what is the benefit of higher lumens? If it was a thrower I could understand. But as a flood I don't understand the benefit.

For any given beam pattern, the higher the lumens the brighter the beam (obviously) and the longer the reach/throw.

Also, the turbo head described in my previous post that I'm using on the next "build" uses the Cree XM-L2 emitter, which is larger and has a higher current/lumen capability vs. the Cree XP-G2 in the head of my current QTA.

BTW, for some excellent reviews of lights, beam patterns, etc., I can recommend the http://flashlightguide.com website as an excellent resource.

[Rich]

I thought about going AA for EDC? I have a fenix LD 22 that's takes lithium, alkaline , AA.

Ive had the light for 2 years now and haven't had any problems UNTIL last week.

A AA Dura Cell Copper Top started leaking by the tail cap. And the light wouldn't work. After cleaning the tail cap out it worked for a short time then stop. I did more cleaning and couldn't get it to work. Fenix / Casey is sending me free switch/tailcap.

I was lucky because I check my AA batts everyday because I knew AA have that problem. I couldn't imagine if I left it for a couple days.

Made me rethink using AA for a EDC/ SD light.

BTW
I've been using 123 batts for decades now and haven't had one leak yet.

I have no problems carrying 2- Surefire P2x fury . Cargo shorts makes it simple for me..

[UNK]

Here is a pretty cool feature from Streamlights website. It describes the three beams they have then shows what you would see with those beams in a variety of scenarios.

http://beamdemo.com/situations.html

[BobLoblaw]

I picked up one of these after this great review. I really wasn't that impressed at first but this light is growing on me. My EDC is the LED Lenser P3 AFS P or the Surefire LX2 depending on the occasion so I was hoping this would bridge that gap.

On a standard AA, I can't really tell a difference between this and the AAA 70 lumen Lenser (when they both have new batteries). Momentary burst would make this light a home run but overall I like the design, size, and 4-7s mode switch-ology. I'm going to get a spare L2 body since 14505s are harder to come by than 123As.

[NH Shooter]

Rich, I too have had my share of leaking alkaline batteries and no longer use them in my lights. For a 1.5 volt AA, I generally use lithium batteries or until recently, NiMH rechargeable batteries.

Bobbj22, the jump to a 3 volt 14505 battery is pretty dramatic in this light. For an EDC light that gets regular use, I think 14500 Li-ion rechargeable batteries makes a lot of sense.

[runcible]

SN,

I still run/plan-to-run a 2-cell at work; but am looking for something smaller for running and the like. When it's time to replace the VTAC, I'll take a gander on the Quark 2-cell, based on how the 1-cell shakes out. :)

[BobLoblaw]

Bobbj22, the jump to a 3 volt 14505 battery is pretty dramatic in this light. For an EDC light that gets regular use, I think 14500 Li-ion rechargeable batteries makes a lot of sense.

You were right. Those 14505s make this an entirely different light. Bought 14500s too. This combo is awesome.

[Irelander]

Thanks for the cool review and details about building your own "Quark Special". I too am a Quark fan. I've been faithfully carrying the older version of the QTL for over 5 years. Its a great light that I have never went a day without using since I got it. I have mine set to max lumens (~210 lumens) with tail tight and "moonlight" mode with tail loosened. "Moonlight" mode is great when navigating the house without waking the kids or making the nosy neighbors nervous.

[Seven_Sicks_Two]

The QTA was my first EDC flashlight. After carrying it for a year or so, I picked up the Surefire EB2 Backup with the tactical tailcap. Going from 100-ish to 500 lumens was cool, but the bigger light just didn't work for me. The bezel wore holes in my pockets, the clip was fragile and if I wasn't careful, I'd get light NDs in my pocket while seated. It wasn't a huge deal, but it really burned through those expensive Surefire batteries. After 6 months or so with the larger 2-cell Surefire (and two broken pocket clips) I'm back to carrying the QTA. My only gripe with the smaller light was that it wasn't nearly as bright as I was accustomed to with the Surefire. I'm going to have to try some of the battery options listed in the thread and get some more lumens!

[BobLoblaw]

Is there a charger preference for the 14500s that seems to work well?

[NH Shooter]

After 6 months or so with the larger 2-cell Surefire (and two broken pocket clips) I'm back to carrying the QTA. My only gripe with the smaller light was that it wasn't nearly as bright as I was accustomed to with the Surefire. I'm going to have to try some of the battery options listed in the thread and get some more lumens!

This latest version of the QTA (with the Cree XP-G2 emitter) on a 14505 primary or 14500 Li-ion is really impressing me. I've been carrying it and using it every day since I started this thread, giving it a work out when I take the dog out for her night time walk. I use a few short bursts on max, usually 3 to 5 seconds each, to survey the entire back yard and then use the medium setting of 26 lumens the rest of the time. I can easily turn the bezel in one hand to change between the 26 and 246 lumen settings.

For anyone who needs a good EDC light with capable output and doesn't want to bother with rechargeable batteries or modifications to the light, just order the QTA and a supply of the TI 14505 batteries. The nice thing about the stock QTA is is that you can use any AA battery, though 1.5 volt batteries will reduce max output to 130 lumens, which is still a very usable amount of light.

Not able to leave it alone and seeing how much light I can wring out of the QTA, I have a QT2L-X Head with Burst Mode (http://www.foursevens.com/products/UQA8) on order, which will produce about 750 lumens for the first 60 seconds then settle in at 420 lumens after 2 minutes and hold that output until the battery is depleted. This head is rated for 3 to 9 volts so I'll be using an AW IMR 14500 LiMN Rechargeable Lithium Battery (http://www.lighthound.com/AW-IMR-14500-LiMN-Rechargeable-Lithium-Battery_p_3644.html) (4.2 volts hot off the charger, 3.7 volts nominal) that has the amperage capacity to support the burst mode function (standard 1.5 volt AA batteries will not operate this head). I have also ordered an Xtar VP2 (http://www.xtardirect.com/products/xtar-vp2-charger) charger to keep the 14500 LiMN battery charged. I'll obviously hold on to the current QTA head for use with standard AA batteries should the need arise.

I'll update this thread in a few weeks after I have used the new head/battery combo and share my findings.

[NH Shooter]

Is there a charger preference for the 14500s that seems to work well?

Based on my research, there appears to be many decent chargers on the market. Xtar chargers (http://www.xtardirect.com/) get good reviews, I have their VP2 on order myself.

Although Ive been carrying flashlight for a long time now I don't know much about them as far as Tech. I replaced the switch on my LD22 and it works fine. Hind sight being 20/20 maybe I should order another switch??

I know nothing about the rechargeable 18650 for 123 battery flashlights. / 14500 for AA flashlights!

Ive been told by guys smarter than ME not to use the rechargeable for EDC / SD??


I have a spare /back up flashlight I carry. Its a 750lumen 2-123 battery flashlight made by Nitecore. It also takes the 18650 battery? The 18650 batts are cheap same with the recharger and I'm thinking of testing it out.

I know there are several different voltage 18650 batteries that Nitecore makes. Any Idea how long do they hold a charge?? If they can hold a charge for 24hrs I might give them a try.


BTW Are you saying the lithium AA wont leak as bad as the alkaline? When I use lithium AA in my gen 1 LD22 I loose my low mode and I use the low mode often.

[olstyn]

I know there are several different voltage 18650 batteries that Nitecore makes. Any Idea how long do they hold a charge?? If they can hold a charge for 24hrs I might give them a try.

I can't speak to the specific Nitecore product that you're asking about, but I run Tenergy RCR123a rechargeable lithiums in my QTL, and I get several MONTHS of usage out of them per charge. Admittedly, the light is on only a few minutes/day, but so far, at least, there doesn't seem to be any issue with them holding their charge.

[NH Shooter]

Ive been told by guys smarter than ME not to use the rechargeable for EDC / SD??

Rich, I'll attempt to offer some insight on this question without trying to go overboard with the technical.

In terms of the standard run-of-the-mill NiMH rechargeable batteries you can buy anywhere, the only downside I can think of from an EDC perspective is their limited capacity vs. a primary battery, which means you need to make battery recharging a part of your regular routine. These batteries also tend to die fast when they become fully discharged, giving limited warning by way of a dimming light.

In the world of the more advanced lithium-ion rechargeable batteries, there are two general categories: protected (http://www.lygte-info.dk/info/battery%20protection%20UK.html) and unprotected. Along with higher capacity and long life, one of the downsides to Li-ion batteries is that they are easily damaged (or even ruined) if they are discharged too far. So the protected versions of these batteries have a tiny circuit under the wrapper that disconnects the battery from the load when voltage falls to the point of risking damage to the cell. Unlike a regular battery that will continue to discharge making the light slowly grow dimmer (within the voltage requirements of the light), this disconnect is usually abrupt, which means that the light will suddenly go out when in use. To effectively use these batteries, you need to learn how long the light will run before the battery drops out and/or recharge the batteries regularly. Carrying a spare battery for critical-use lights is highly recommended.

Unprotected Li-ion batteries don't have the circuit. These will continue to discharge past the minimum charge needed to prevent damage, but you may end up damaging/ruining the battery if you let that happen. Sometimes the voltage in an unprotected battery will fall below what is needed to operate the light, but still be above its minimum voltage to avoid damage. That is the case with the combination of head/battery described in my last post; the battery is 4.2 volts fully charged and has a minimum voltage of 2.5 volts, while the light needs at least 3 volts to operate. Once battery voltage drops to under 3 volts, this particular light will rapidly dim from full output to nothing over a few minutes, which at least gives some warning that the light is about to quit. The graph below shows the output vs. runtime of the specific head/battery I referenced in my previous post;

http://i38.photobucket.com/albums/e129/ti-force/QT2L-XAWIMR14500Max.png

Notice how as the battery falls below 3 volts, the circuitry in the light tapers the output to zero over the course of about 5 minutes. This is a MUCH better scenario than having the circuit of a protected battery suddenly disconnect without warning.

This is what the output of a light looks like when the battery protection circuit (of a protected cell) cuts in;

http://flashlightguide.com/wp-content/uploads/2014/06/SureFire-6PX-320-lumen.jpg

In the above graph, the red line is that of protected Li-ion batteries, the blue line are primary (non-rechargeable) lithium batteries.

FWIW, I use both rechargeable and lithium primary batteries. My EDC lights use Li-ion batteries and managing the batteries is part of my regular routine. A good charger and a digital multi-meter make this task much easier. For emergency-use lights that sit in a drawer or in the car, lithium primary batteries are the way to roll due to their extremely long shelf life (10+ years, "load 'em and forget 'em"), capacity and good performance (especially in the cold). In most lights, they also give fair warning that they are nearing the end.

For those who use their lights on a limited basis and don't want to bother with battery recharging, lithium primary batteries are IMO the best bet. My wife (who is about as non-technical as they come) carries a Streamlight ProTac 1AA in her purse, loaded with a TI 14505 lithium battery. For those of us who don't mind (or even enjoy) being geeky and keeping our pocket torches burning their brightest, the various forms of lithium-ion rechargeable cells rule the roost.

I hope this addresses your question!

I purchased a QTA yesterday to replace a lost Streamlight. I was considering going to rechargeable batteries as well. That post was very helpful. Thanks, NH.

[Rich]

That help a lot. And I thank you. I think I will stick with non rechargeable for now>

I notice that 4sevens has there older 2-AA flashlight for cheap. My gen 1 LD22 is 190 lumens and I seem to use it the most although I don't EDC it. Could make a good Christmas present to myself.

For EDC I wear wrangler cargos 99% of the time and I can carry 2-132 flashlights in the side pockets. Surefire P2X Defender 500lumen & the smaller Nitecore SRT5 750lumens. Has to be close because its a lot brighter than the 500lumen P2XD

[Rich]

1 -AA battery light caught my eye. ARMYTEK A1 XM L2 w/ TIR optics. The specs look good also. price around 55 bucks.

Since I know nothing about flashlights other than using them I thought I would ask your opinion?

Rich, it looks like a rugged light that gets good reviews. The reverse-clicky with no momentary operation is a disadvantage IMO, though. Here are a few links I found;

QTA Update

As I mentioned a few posts ago, I ordered a few new parts for my Quark QTA;


One QT2L-X Burst Mode head, which will provide up to 780 lumens for short bursts
A pair of AA-sized IMR 14500 Lithium-ion rechargeable batteries (only one needed at a time)
A Xtar VP-2 charger



I’ve been carrying the QTA everywhere, all the time since I started this thread and it has worked out very well. With the deep carry clip and the DIY finger lanyard, it’s easy to carry and quick to get into action. For me, the UI and form factor of this light are perfect for my EDC needs.

The stock QTA powered with the 14505 lithium 3.0 volt primary battery is excellent as is (and probably more than adequate for most users), but I was interested to see how much of an improvement the new burst-mode head would make. I’ve been using the new setup for about a week now and I can report that where the stock QTA is excellent, this setup is incredible in terms of light output for an AA-size flashlight. It’s really something you need to experience first-hand, beam shot photos do not do it justice.


http://www.canonshooter.com/photos2/qta-6.jpg

Also shown is the DIY finger lanyard with break-away connector so if someone gains control of the flashlight, they can’t tourniquet-your-finger-off.

Technical Considerations

The QT2L-X Burst Mode head is designed for multiple cell operation and will work from 3 to 9 volts with full burst mode. This head is normally used with two CR123a cells. To get the head to work with one cell, a 3.7 volt Li-ion rechargeable cell is required. Another technical hurdle is that in burst mode, the head draws nearly 2 amps, which is beyond what a typical AA-sized protected Li-ion rechargeable cell will deliver, so an IMR high-current type Li-ion cell is required.

Due to the power requirements of this head, IMR 14500 cells are the only AA format cells that will provide the juice required to fully power the head. A single AA alkaline battery will not activate the QT2L-X head at all, not even in a low setting.


http://www.canonshooter.com/photos2/qta-7.jpg
Light configured as I now carry it with QT2L-X head powered by 14500 IMR battery.

Beam Pattern

The QT2L-X head uses the larger, higher current capacity Cree XM-L2 emitter instead of the Cree XP-G2 emitter found in the QTA head. A byproduct of using a larger emitter in the same size head/reflector is that the angle of the beam is wider, meaning that the QT2L-X head casts a wider, more “floody” beam. Since the lumens are spread out over a larger area, this would usually mean the wider beam does not have as much “throw” or reach as the narrow beam. However, due to the huge increase in absolute lumen output, the QT2L-X head in burst mode easily outperforms the QTA head in every way.


http://www.canonshooter.com/photos2/qta-8.jpg
QTA head with Cree XP-G2 emitter on the left, QT2L-X Burst Mode head with Cree XM-L2 emitter on the right.

Run Time

Along with losing the ability to use any AA cell, run time of this setup is limited. As you can see in the graph below, in continuous use the light will start in burst mode and then taper down and settle at about 420 lumens after a few minutes and hold that output for about another 25 minutes until the IMR 14500 cell is depleted.


http://i38.photobucket.com/albums/e129/ti-force/QT2L-XAWIMR14500Max.png

The duration of Burst mode is regulated by a timer circuit function so by simply turning the light off and then back on, the timer is reset and you can stay in burst mode. However, with all of that amperage flowing through a small, low-mass head it gets hot very quickly and risks damage to the head if you were to hold it in burst mode for an extended period of time. Even after just 10 seconds in burst mode, the head gets warm.

With burst mode programmed for the head tightened to the body, I have the medium setting programmed for when the head is loosened. Medium mode on the QT2L-X head is 55 lumens, which in combination with the very wide beam pattern is really a very usable amount of light. In fact, I find this setting perfect for about 95% of my use of the light. On the single IMR 14500 cell, there is nearly four hours of continuous run time on the medium setting.

Use and Performance

I do not believe that I can over emphasize the unbelievable amount of light this set up produces in burst mode. In fact, in a side-by-side comparison with my 600-lumen Surefire Peacekeeper, the QT2L-X appears brighter over a larger area for the first 30 seconds in burst mode. Of course, the Peacekeeper can hold its output much longer and has a narrower, warmer beam compared to the QT2L-X.


http://www.canonshooter.com/photos2/qta-9.jpg
Size comparison of Quark QTA and Surefire Peacekeeper (shown with DarkSucks.com titanium clip).

In practical use, I use burst mode just that way – in short 3-5 second bursts to check out the surroundings and dark corners. Used this way, it is extremely effective and switching down to the medium setting is perfect for walking down a dark street and being able adequately light objects out to pistol-fighting distances. In terms of using the QT2L-X as a self-defense weapon, I can’t even imagine what it would be like to get a face full of burst mode at close range.

Conclusions

The stock QTA, which is rated at 130 lumens maximum with a standard AA alkaline or 246 lumens maximum with a 14500 rechargeable Li-ion or a TI 14505 primary cell, has so far proven to be a very portable, pocketable and effective EDC light. Though it will be some time before I can attest to its durability, it has so far not disappointed. Combined with its ability to use any AA battery, from common AA alkaline to specialty batteries such as the TI 14505 3.0 volt primary cell or rechargeable 14500 Li-ion cells, there will never be an issue with keeping the QTA powered.

For those looking for a palm-sized nuclear reaction and can live with short run time, specialty batteries and regular battery recharging, the QT2L-X Burst Mode head in combination with an IMR 14500 rechargeable cell is a true “hot rod” EDC light. At least for me, an EDC light is not intended for extended use/long periods of time. When I expect that I will need light for extended use, something like the SF Peacekeeper goes in a pocket and the QTA becomes the backup. I also keep a long-run-time Surefire 6PX Pro in the car for emergency use, which can be called upon to serve as the primary light if the QTA is all I had in my pocket when I left the house.

using two CR123a lithium primary batteries. It also offers three times the run time of the modified QTA though in a larger package.

We are fortunate to now have so many great lights from so many manufacturers to consider for EDC use, and I have to say that the Foursevens Quark QTA is most certainly one of them.

DonW, I just replied to your PM;

The AW IMR 14500 LiMN worked fine in my stock QTA. The QTA head is rated for .9 to 4.2 volts and the battery will come off the charger at 4.2 volts maximum. For a stock QTA, the protected AW 14500 cell might be a better choice, though.

Yes, modes can be switched without having to turn off the light.

Good luck, let me know what you think of the light!

Got your pm - I'll reply here:

I got my QTA yesterday and it exudes quality. This morning I inserted a eneloop and programmed the tightened mode to moonlight, .2 lumens, and quickly saw the preflash (ugh). Tried it several times and there is no discharge, like I had red - preflash (pf) is constant. I didn't anticipate the pf. For those who don't know what preflash is, it's a quick momentary flash of a higher lumen when you turn on a low setting - in this case the .2 moonlight.

So, I need an XML led head, and ordered the Quark Tactical QT2L-X Head with Burst Mode, and I'm getting your recommended AW 14500 protected cells, and an Xtar VP2. ... :D

[NH Shooter]

You'll like it. I set mine for burst tightened and medium (55 lumens) loosened, and have left it that way. The circuitry on the burst mode head is different: with the light turned on, switching from burst to medium is a "soft" transition with no pre-flash. You'll see what I mean when you try it. FWIW, the pre-flash didn't bother me. At least with mine, if it was left off for a few minutes it didn't occur.

BTW, you should use a high-current IMR cell for this application, this one has worked fine for me - http://www.lighthound.com/AW-IMR-14500-LiMN-Rechargeable-Lithium-Battery_p_3644.html

I noticed the same thing so instead of ordering a new head (which happen to be back ordered anyways), I just bought a QT2L-X and switched the heads. I only use high and medium on the dual cell. Now I have a high lumen/short runtime light and a medium lumen/long runtime light. I also went with the protected AW 14500 cells (and protected AW 17670s for the dual cell) and VP2 charger.

However, I took the low ride clip back off the single cell because it torqued the light in an awkward way causing the head to deliver an annoying poking sensation.

[DonW]

Interestingly, Surefire's 2015 products has the PMX Fury, which takes either 3 CR123A or 2 AA.

It sounds like the Quark line will be no more. Four Sevens has discontinued them for the "next generation" of lights which appears to have a different user interface. FourSevens was sued by Surefire a while ago and this cancellation of the Quark line was one of the requirements of the settlement.

Fenix also stopped using the head tight/loose UI after a similar patent issue.

My guess is that Surefire owns the head tight/loose utility patent, and even though they don't use it they are starting to put legal pressure on those who do. Such is life with patents I suppose.

If that is how this all shakes out, I am going to be disappointed as the head tight/loose UI is my favorite feature of the Quark line, and nobody else other than some custom makers are using it. You'd think having a light with a default of high and the ability to select low before turning it on would be more popular. SF does it with pressure switches and Quark did it with the bezel tightness, and that's really about it.

I picked up a QT2L-X that was in stock just to shore up my collection in case these become unavailable in the future. Curious to see what the next gen of Quark lights brings.

Where did you read this Tom?

Where did you read this Tom?

Pieced it together from a few different CPF posts.


We're here to stay. Quarks are discontinued for two reasons. 1) it was part of a settlement agreement with surefire and 2) to make way for the next generation of Quarks in Q2.

Fenix quoted me via email that they will never do bezel mode adjust again because of a "patent issue." A search of US court filings shows both Surefire vs Fenix and Surefire vs 4Sevens.

[SouthNarc]

Roger that.

[TCinVA]

Damn. I need to order a couple more.

This is news to me. I just ordered another burst mode head and tail cap so I'll have three complete Quarks.

Here's the 4sevens post mentioned above (http://www.cpfmarketplace.com/mp/showthread.php?318754-Quarks-Out-of-Stock&p=4867104&viewfull=1#post4867104) talking about Quarks being discontinued.

[NH Shooter]

Thanks Don.

So many of the "Asian lights" feel gimmicky and fragile to me, while Surefire lights feel rugged and business-like. The Quark tactical models struck a good balance by being able to program out all the gimmicky modes (not have to cycle through them every time the light is used) and appearing to be reasonably well made.

On one hand I can understand the need to protect intellectual rights against the never-ending Asian knock-offs; one the other hand, the only real issue I was aware of with 47s is anodizing in the tail cap threads that enable lock-out, and 47s addressed that. I'm sure there are other patent/legal issues involved and hopefully not a matter of SF simply trying to suppress competition.

[joshs]

SF does it with pressure switches and Quark did it with the bezel tightness, and that's really about it.

The magnetic control ring lights, like those from Sunwayman and Jetbeam, can also do this, and so can HDS systems "Rotary" line.

[Tom Fineis]

How are those for durability and use under daily conditions?

[joshs]

I carried a Sunwayman M10R daily for a little over a year. Other than some wear in the anodizing, the light is perfectly fine.

HDS lights are generally considered to be some of the most durable and reliable flashlights available, but you do have to pay quite a bit more compared to Chinese made lights.

[DonW]

Take away what you want from this. Several days before the post by Foursevens about discontinuing the Quark line, I called them about when they would have the QT2L-X Head in stock again. He paused a bit and had a side conversation with someone, then said to put my order in and they will fill it. True to his word, it went through like a normal order and I have the high voltage XML head to lego with my QTA. I also got a QPA tail cap (which was also out of stock). I didn't talk to them about that particular order, but rolled the dice and it went through like through a goose.

[NH Shooter]

Don, I suspect there will be a short window to do this, but 47s will need to close it down quickly for legal reasons (I would have to believe).

Online vendors still have some stock but once that is gone Quark V1 will be done.

BTW, have you fired-up that burst-mode head? ;-)

Having spent much of my career trying to prevent theft of my employer's IP in that particular country, I don't really see an 'other hand.' I only wish I could make my customers understand that by buying copy product they're accessories to theft.

Having spent much of my career trying to prevent theft of my employer's IP in that particular country, I don't really see an 'other hand.' I only wish I could make my customers understand that by buying copy product they're accessories to theft.

Understood. I was once a product manager for a major U.S. valve manufacturer and saw the blatant knock-off issue first-hand.

In this case, the 47s Quark was in no way a direct knock-off meant to mislead the consumer that they're buying a Surefire product. In fact, disputes over patent infringement is pretty much SOP in any industry, even to the point where competitive derivatives of patented products are assigned new patents and then those new patents are challenged in court. As you know, those with the deepest pockets can afford the best patent attorneys and effectively leverage those less-able financially to defend themselves. Not saying it is the case here, but I know that this kind of situation - a claimed patent infringement by a major player against a smaller player - sometimes occurs for no other reason than to suppress competition. Sometimes, it goes the other way when a small player cannot prevent possible infringement when a larger player does it to them.

In the end, all we can hope for is that justice is served for honorable reasons.

I've been very pleased with the Quark AA Tactical R5 w/ AW 14500 I've EDC'd for the last five years, and hope the QP2L-X lives up to its record as it'll be taking the R5's place in my pocket.
I'm thinking I may buy another 2L body to use with the R5 head and my tactical tailcap and will use it as a nightstand flashlight. Alternately, I may just put an Energizer Lithium cell in it and keep it in my car.

I'll have to post up a 'family' pic when I get the QP2L-X. The AA Tactical has been well-used.

[NH Shooter]

What kind of runtimes do you get out of the 16650 in the QT2L-X?



Have not tested this set up directly but in other lights I find I get equivalent run times with the KP 2500mAh 16650 cell as a pair of CR123a primaries. I would expect the same run times as stated on the 47s site for the QT2L-X with 2-CR123a cells.

For my remaining low voltage QTA head, I lego'd another single CR123A light with an L Series body (single CR123A) and a tactical quark tail switch.

[MichaelD]

I've had my QP2L-X for about a week now and I'm pleased as punch. The 780-lumen light sure lit up a dark South Ballroom at Salt Lake Comic-Con FanX this last weekend, and the strobe was fun to use while everyone was dancing during the breaks at the Cosplay Contest.

I don't know much about flashlights, but this thread has been very useful. Thanks for that.

I just ordered a Quark Tactical QTL Gen 2 with a Quark L (single 123) Body to see how I like a shorter carry light. (I hope I'm correct in thinking the single 123A battery will power the head on this light?) I'm hoping it carries and handles better than the older Surefire E2D Defender I've been carrying for years. I have a feeling I'm going to like the extra Deep Pocket Clip I ordered too compared to the cruddy clip on the Surefire. I'll see how it goes.

[Rich]

Very cool little light.
I still haven't dove into the rechargeable batteries.

I`m guessing isn't that a Darksucks clip that on your peacekeeper ? Does the clip work good?

If so I will order one for my P2X Defender. I don't like the raven clip because I don't use the ring

Yes, it keeps its programming when you change its batteries.

I've been really impressed with the two Quark Tactical lights I bought. I like the mode options and the quality. The deep pocket carry clip is a nice accessory too.

It's always dangerous for a flashlight addict to read this forum. I just ordered a QTA off Amazon after reading your review.

Flashlights, pocket knives, and handguns.

Little boys don't really grow up, just get larger. Our cap guns turn into Glocks 1911s, N Frames, etc, and our trikes turn into pickup trucks. Pocket knives and flashlights evolve, quality wise, but in the end, we are still into the same stuff that we were into at 6 years old...

How does the QK2A-X compare to the QT2A-X? Generally speaking and with specific emphasis on the user interface. Simple is good.

It looks like you have to special order the desired settings you want.

I'm not terribly familiar with flashlights beyond the Costco tactical lights I've been using till now.

Quarks are Back!

And they offer programming for the lighting selection you want. Hi only , low med hi, etc etc....

FYI: The new (2)CR123A Smart Quark lists a lumen output max of 950. Status is pre-order only.

I like FourSevens, and have a few of the previous Quarks. A couple of things to be aware of with the new ones . . .

Changing modes requires pressing the tail switch off and on again within about 1 second. If you are using the light intermittently to search for someone who means you harm, it is way too easy to change modes at exactly the wrong time. Reducing this time to about 0.5 seconds would likely help considerably.

The strobe rate is about 10 Hz. That slow a strobe rate definitely slows one's ability to perceive what is around them when using strobe mode. 14-15 Hz. is much better in that regard, and allows me to perceive what is around me at about the same speed as a solid beam.

I had been wanting a QTA for a while and providence would have it that I won the Karma giveaway for one and received it just prior to my birthday. Pretty awesome! I had been using a older Quark Tactical 123 so I gave that to my wife. I like that the QTA is longer and the deep carry clip is great. I bought a XTAR 14500 battery and Nitecore UM10 charger from Battery Junction. This seems like a winning combination. And my wife is happy that she gets a nice light and I get a new one and it only cost me the price of the battery and charger.

ETA: I'm hoping to order the QP2L-X Head with Burst Mode soon.

Follow up -

My 14500-powered QT2L-X Quark shines on. It remains my EDC light, has traveled near and far with me, been x-rayed numerous times by TSA, dropped, misplaced, etc. I still have no reason to look any further for EDC light.

I'm resurrecting this old thread.

Today I'm still carrying my QT2LX and it still works brilliantly. It's been all over the world with me and hasn't let me down after 6+ years of EDC. I love the UI still as I have it set for Turbo/Burst with the head fully tightened and medium with it loose.

So now my question is: what else is out there these days? Surely someone has a better product out by now or at least an equivalent? One day this light will either go missing or fail in some way. I'm looking for:

-Similar size (7/8" Dia x 4.5"L)
-Similar output (800 lumens, but 700+ is fine)
-Simple switchable UI

I still EDC the little Quark, but on a 1-CR123 body with a 16340 700mAh Li-ion cell inside. It's small, lightweight and powerful. When I want more I carry one of the Malkoffs, like the MD3-M91B seen in back of it.
