This PLT PFA-60C15CL120V C15 clear bulb is high temperature coated to prevent glass shards from contaminating food or creating other hazards. The P.F.A. coating (Teflon) around the bulb is a very unique material that combines extreme temperature resistance with high clarity, excellent adhesion and high impact strength. Operating at 60 watts, it has a medium (E27) base and an average life of 8,000 hours. When safety is a concern, shatter resistant light bulbs are the only option.
