Surefire makes THE BEST flashlight without a shadow of a doubt.
They are extremely bright, waterproof, durable, and oh yeah, even stop a bullet, and keep on working. (it was in an article in a magazine) A man had his surefire in his shirt pocket, reached back in his truck to get his 22 mag, and bang! the light stopped the bullet, saved his life, and it still worked after being shot. I have about a dozen surefires, They make some really nice LED lights you may want to check out, The Aviator, It has a white led, blue led and red led. Really nice light, very bright. The G2's Ex2's are very small and bright as well, but they are xenon.
