IMHO, those super urber lights in CQB are just shat. They light the walls up so much it hurts your eyes...not to mention other peoples eyes.
personally, I only use a small LED light on my gun. Soft white. Doesnt give away my position and just enough light to see where I am going. I only use it to see where I am going without taking my hands off my rifle.
The idea of using a insane light to blind your opponents is great in real life, but it just hurts the eyes of your friends at night.
ofcourse, you could always strap light like mine to your rail and go CQB
yah, thats 12,000,000 candlepower
At night, you shoot with your ears, not your eyes.
