find an LED light as bright as an SF M6........ i didnt think so. I never buy incands any more, LEDs are much more effecient, but if i needed something extremely bright, then i might buy an incand. Some say that incands are brighter than leds, and that is true, but when it comes to small lights like 1x123 and 2xcr123, leds are just as bright- fore example, HDS puts out 60 lumens, and there are no 1xcr123 incands that put out that much light, and the Surefire L2 stays right up there at the top in terms of the brightest 2xcr123 lights. But when it comes to larger lights, the incads will win because of the fact that current technology limits the brightness of LEDS.
