Since a weapon mounted light was mentioned, I will add a thought or two.
Do not get caught up in the brightest light game. Know what you need and what your intentions are. I started the room clearing thing with long guns in 94 when the hot lick was a Surefire incandescent with a whopping 60 lumens.
Now these little leds are 1200-2000. You can have too much light. I like about 500 for inside work and 300 will get it done. Wont wash out your sight or dot on white walls and provides enough ambient so that you can ID a target without muzzling it at a low ready during the challenge and assessment phase.
If you need 100-200 yard light you need to consider throw and spot. Also know that with none magnified optics you cannot ID a target at that range. So in none mil work that means he has to shoot first or point a weapon at someone and you were able to track his movements to where you will shoot back to insure its the correct guy.
Try you light shooting from all positions and on all surfaces. That great high powered light when standing can suck when on dirt in the prone. Each dust particle becomes a mirror and you will lose your target and ability for follow up shots.
Learn how to shoot and your shooting technique then mount the light to accommodate. Consider pro and cons of mounting the light at 3, 6 or 9 o’clock. Because they exist and back in the day option were limited.
For me, 12 o’ clock, in front of my front iron sight became king. The light when mounted here must allow and iron sight picture over it.
