I did NOT need to see this today. Surefire G2 with an LED: 80 lumens output for 12 hours. Son has one of the standard G2 lights, I need to find if they sell the LED lamp assembly to put in the old light: if so, he'll love it. Same batteries but 12 times the runtime, damn.
Also, heard from him the other day. It's now hitting 90's in his area for highs. In March. Yuck.
