I think the Dewalt site lists them at 225 and 350 respectively but I could be mistaken. I do know that 14.4v is in the 200-250 range and the 18.8v around 325 to 350.
A friend of mine has a 19.2 volt light made by...I forget the brand but its dark green and orange. Might be Black and Decker. But anyways, its nowhere as near as bright as a Q40 but puts out a much wider area or yellow light.
Hey does anyone have any of these high powered lights from dewalt or black and decker and care to comment how good is this compared to some lights out there? i seems like a very interesting rechargeable flashlight and at 300+ lumens it seems very nice for outdoor use!
