Like so many others, I went with this Dewalt light because it uses the same 18v battery as my other cordless tools. Like so many others, I am very disappointed with these lights. I also own the DW908 and hate that thing too because you can never get the beam aimed where you want it. My buddy sprayed brake cleaner on that one to clean it off and the cheap plastic fused the power switch to the casing so it's toast. The DW919 is a whole other mess of poor design and even poorer usability. The head is too heavy for the flexible neck so its always toppling over or moving out of position. You have to constantly move the head back and forth to position the beam. The beam is very weak and dim even on a fully charged battery. After it moved for the hundredth time while working on a brake job, I threw it out of the way and the flexible neck broke where it attaches to the head. Good riddance to this piece of junk. I love my other Dewalt tools but I'm going with another brand for my work lighting.
