Popular Hot Rodding held their annual Engine Masters competition last week, and one of the team members there had a flashlight I built, a Surefire C2 Centurion modded with a Cree R4 XP-G run at 1.4 amps off an AW 2600 Mah 18650. He said he got a lot of compliments on the light.
Here is a pic of him inspecting the oil pump on a Ford engine. It kind of looks he's TIG welding, eh?
