Hand-held lights in real life are a huge complication of things and are often oriented in the wrong direction... in many cases doing more harm than good.
Rifle lights to me are less clear cut. We generally have two hands on the rifle, so manipulating a momentary switch is easier with the support hand if set up right. The issues of threat identification and management are still there, but some of the problems with momentary use that affect handgun WMLs aren’t as bad with rifle WMLs. Add to this that rifles are more commonly associated with military use where leaving a light on is more of a potential problem than in US law enforcement/self defense situations and momentary activation becomes a more attractive option. I still like the option of a constant-on, which is why my Modlite rifle light with the ModButton Lite has a Surefire tailcap with a constant-on option. One of my other rifles has a Streamlight PL something or another and that has both momentary and constant as well, and my AR pistol has a Cloud Defensive OWL that has both... But the OWL has a digital switch and it’s a tap for constant and hold for momentary of which I’m not a super-huge fan.
As for strobe functions and the idea of manually strobing a light... I know of European LE people who claim very effective use of strobe. In a non-Lethal situation, maybe dealing with a drunk or something this may be a decent tool, but there are some big disadvantages to strobe and in a lethal or potentially-lethal situation it’s even more of an issue. This includes difficulty perceiving movement, losing visual input of what is going on since you’re only getting light part of the time, the potential for effects of the strobe to hurt the user in addition to the suspect, and for pretty much every light with a strobe function I’ve ever used the complicated user interface (switching) that more often than not leads to strobe being activated unintentionally. This goes for other complicated functions like low/high and all the rest.
I don’t feel strobing is the same as intermittent light use when searching - whether with a hand-held or a WML depending on circumstances, I totally agree with this and have seen the effectiveness from both the user and the bad guy in force-on-force. This is where the momentary function on a light like an X300U is a good thing, since the toggle is a bit... tough. On the Modlite there is no momentary function needed, and I wish manufacturers who’ve incorporated digital switching would keep it simple and go constant only... press on... press off.
My department issues the X300U, so that’s the majority of what I see, but we have a good number of participating agency recruits in the academy and a lot of them are running Streamlights. Since most of those come from the factory with strobe enabled, I’ll tell them when we start our low light training that they can do what they want, but if they find they don’t like the strobe to let me know and I’ll turn it off. I don’t think I’ve ever had a recruit get past low light day 1 without having me turn off the strobe.
