which is how long?
Did you not read post #18? I have no idea as I don't have one and there are no reviews with measurements out that I am aware of. Eagletac says 1 - 1.4 hours with the CW version. So I would guess about the same with the NW version but, it will be putting out about 10-15% less lumens.
