SureFire has sold numerous 6P, G2, G2Z, Z2, and M95x tactical illumination tools over the years, and many customers still rely on them because they have never failed their owners. The SureFire P60 fits 6-volt SureFire incandescent flashlights and Weapon Lights with a 1.25-inch bezel. It delivers 65 lumens of white light with about 1 hour of runtime and is designed by the same engineers who created your SureFire handheld light. Use only genuine SureFire replacement parts. Note: Do not use rechargeable LFP 123A batteries with the P60 lamp assembly or other incandescent illumination tools.
