    BF(QD)WMLs

    As most of you already know, I'm a Malkoff fanboy so it should come as no surprise that I like using them as WMLs too. The wide selection of mounts for 1-inch body hand-held lights opens up many possibilities. :-)

    I am also a proponent of the KISS principle for ARs, and I strongly detest seldom-used "stuff" living fulltime on the handguard. I'm not an "Operator" nor am I LE that needs to clear rooms as part of my daily activities, so I have the luxury of keeping things pretty simple (and lightweight, and not bulky, etc.). That said, the ability to quickly attach (and detach) a powerful light has strong appeal to me. Since the light is not living on my rifle 24/7, using something larger and heavier is of little consequence to me.

    The (former) fulltime resident Malkoff/Arisaka Scout 300 clone shown below weighs only 3.2 ounces and produces 750 lumens/20,000 lux;

    Lightweight and reasonably powerful, I think it's a excellent setup - providing you don't mind a light living on your rifle 24/7. In another thread I posed the question of how often are WMLs used by civilians for practical purposes, and the response was for rifles dedicated to defensive purposes and night time pest control. That makes total sense, but an AR is not my primary defensive arm and I do not conduct any pest-eradication with a firearm.

    Which brings me full circle back to where I started years ago in terms of ARs and WMLs: I want the ability to quickly attach a WML when needed, but don't want it living on the rifle. If that light can be more powerful than the usual weapon-dedicated light, and also serve as a useful hand-held light, that would be my idea of WML awesomeness.

    Taking this approach, this is my BF(QD)WML setup for my rifle. It consists of a Malkoff Hound Dog 18650 (1,000 lumens/29,000 lux) attached to the port side of the handguard using a Vltor off-set scout mount;

    When the rifle is stowed in the safe, it goes in with the light attached. When the rifle comes out for normal daytime range use, the light comes off, which for me is 99% of the time. Of course with it detached, the HD 18650 is an immensely useful light that can be dropped into a coat pocket or carried in a holster. The beam pattern of the HD 18650 is just about perfect for rifle use, a good blend of throw and spill. Below is the light riding in a kydex carrier and a spare 18650 cell in a waterproof Delrin capsule (the Vltor mount is dropped into a pocket or range bag);

    Of course there are other Malkoff heads that can be used with this arrangement, including the M61HOT (740 lumens/20,000 lux) to create a smaller package.

    As a flashlight nerd and wishing to leverage my Malkoff fanboyness even further, I will be making a change to the light very soon. Using the same MD2 body but with a pair of IMR 18350 cells, I'm going to upgrade to the Hound Dog Super head, which produces 1,700 lumens/75,000 lux. The HD Super head is 2.25 inches O.D. vs. 1.8 inches O.D. for the 18650 version, but there is more than enough clearance for it to fit. The pair of IMR 18350 cells will provide about 20 minutes of full output runtime, and over five hours on low (80 lumens). The HD Super is currently on back-order on the Malkoff site, but as soon as I have my fanboy hands on one I'll update this thread with my impressions and photos.

    No doubt that arrangement will make the "BF" aspect even more convincing. Experimenting with this stuff sure is a lot of fun. :-)

    What head were you using for the 750 lumen setup? I’ve got a 300 and a 600 body I want to upgrade to get them a bit closer to what factory SF lights are throwing now.

    For the 300 body use a cell like this one - https://www.orbtronic.com/cr123a-163...tronic-battery

    For the 600 - https://www.orbtronic.com/16650-li-i...able-protected

    Thank you for the info on this. I have a Malkoff/Arisaka 300 light and want to get more output out of it. I currently have the E1 250 lumen head.

    What kind of runtime are you getting with that E2 head / 16340 battery?

    thanks!

    With a 16340 700mAh cell, you will be limited to about 15 minutes. That said, carrying spare (fully-charged) 16340 cells in a 4-CR123 battery caddy and small pouch is pretty easy.

    Moving up to a 600 series body, you can use a 16650 2500mAh cell which will provide 45 to 60 minutes of runtime.

    I am surprised that 16650 is not more popular and common. It will fit in a narrower light than an 18650 and provide almost as much mAh as some of the cheaper 18650’s (although not as much as some of the newer ones).

    Where should i be looking for a good charger? For work there are a lot of surefires on our rifles and we use a bunch of cr123’s

    I would say the first step is to make an inventory of the light models in use then determine how many of them can use Li-ion cells. Most modern LED lights that use two CR123 batteries (6-volts) can operate on a single Li-ion 16650 cell (4.2 volts fully charged).

    Decent chargers and good quality cells are plentiful once you identify what you need.
