I'm looking to build a bunch of Surefire/P60 sized lights for some local police officers, and I'm considering getting the D1 and D4 (Convoy M1). At least for the D4, is the quality as good as the Convoy branded one? I have an M1 and Solarforce L2P out with one of the officers now to test out.
Or if you guys have any other budget host suggestions, I'm all ears :)
