Bushnell 3-Watt Waterproof LED Flashlight

Anyone know if these lights are any good? One thing I noticed is that this site lists them as 100 lumen maximum output while the Bushnell site only lists them as 81. I'd assume that 81 is the correct number. I don't think Bushnell would underestimate their products on their own website.

Anyway, both places claim that it can run for 4 hour on the high setting which would be nice.

Very good sturdy lights, and yes, 81 lumens. I'll have it changed right away, thanks.

...one more question:

The light supposedly gets up to 4 hours of power on the high setting. Any data on how long it can go on low and medium settings?
