Surefire p61 lamp - SureFire P61 Flashlight Reflector Lamp Assembly for G2, 6P, D2, C2, Z2 & M2 Lights

I got this lamp to replace the P60 lamp in my 6P on my M4. This adds some projection over the original lamp but the greatest gain is in the increase in lateral light output. This is important in a weapon light since scanning for threats is about as important as what you are engaging. I cannot comment on the life of the lamp, but my momentary use should allow for a long life. I would recommend this if you carry a light for personal protection and do not need a lot of battery life since the extra power does drain the batteries faster.
Pros: Significant increase over P60
Cons: None
