Part of the problem as I see (read: biased
) is that light manufacturers market lights as "tactical" to encourage LE purchase, not really having much of an idea what LE really wants. I've hashed this argument out before: no LE I know of uses strobe. It is annoying and dangerous to use in a real tactical situation where I have other force options much better suited to the task and won't disorient me in the process (try keeping your cookies in a dark room shining a strobe on someone, might as well be shining on you...). That said, people who don't usually use the lights in LE settings, don't really mind too much the UIs because they don't have to rely on them via gross motor skills in times of stress. LE likes lights simple: full on when you hit the switch, multi modes are cool, but only if you have to do something unusual to get to it...more than just hit the same switch. Eagletac got it right with the T10C2s where you have to turn the head to change it.
I use momentary on too frequently to risk having a light go into strobe without warning. I don't even use my DBS with a 3SM pill for "tactical" stuff just so I am not fumbling with med and low when I need BRIGHT right now. I instead switch to my CL1H 1SM for that. Olight almost got it right with the M30, but the tail cap "spikes" are not well thought out (really, tailstanding is for blackouts and tent camping, no LE ever needs this either). The T20s would be nearly perfect for LE if they got rid of the strobe and made the switch do only one thing: ON. This is why lights made by Streamlight and Surefire, overpriced and underpowered, are still the mainstay of LE. These manufacturers make a UI that is cop-proof and the lights are simple and reliable, albeit anemic.
