I would be appreciative for any information on vendors and pricing for Surefire replacement lamp assemblies. I want to buy some extra 6V lamp assemblies, both the P60 and P61. Prices I have seen range from ~$16 - $20. Does anyone know if Surefire manufactures there own lamp assemblies? I have noticed that xenon lamp assemblies used in both Surefire and Pelican flashlights have a code on the outside of the reflector that appears to be very similar with respect to font, color, and ink or paint. I am wondering if there is a manufacturer out there that produces lamp assemblies for numerous flashlight companies. Has anyone tried disassembling a lamp and replacing the bulb? Thank you for any information
