if you have already get the battery from the Dewalt 12-volt drill , it make sense to get the flashlight . I get this for a good price and it function as you would expect a flashlight to . nothing too fancy -- decent level of brightness . I be not real fond of the function of the pivot head -- you have to turn the head clockwise to hit specific pivot point , at which you would need to adjust the direction the flashlight be point in -lrb- as oppose to just ratch up and down on the same plane as I have experience on other brand like the Porter Cable -rrb- . it be not a problem but it be not the best design out there . again , if you want to make the most use of you battery , there be not a whole lot of option .
