This light is okay good .... $$ to much ...and still not a surefire... Needs more R&D not weapons ready light more like a nice camping light anyways it's better then nothing.

AMAZING LIGHT!!!!!! High output is super bright (with 123's) low output is equal to a M**light led... strobe function is cool but not a requirement for me... overall superb light.

Just got back from the store after returning the lite because the strobe mode was inop. Looks like I'm going back again because this one doesn't strobe either. WTW? Tried both sets of batteries - no difference. Rather disappointed - if it won't work out of the box what will it do after a while in my backpack?

Good light. Like the dual batteries function and the high low option. Best light I have owned yet.

Great product! Priced right. Should give Surefire a run for their money.
