This LED lamp has a 3 pin bayonet base that is specifically designed to fit the Eaton MEM light fittings. THEY WILL NOT FIT ANY OTHER MAKE OF FITTING.
The original MEM fittings were fitted into new builds so they would comply with part L IEC 60969 regulations and were supplied with 20w low energy comp.fluorescent lamps. The compact fluorescent lamps have now been replaced by a 15w LED version making them more efficient and giving instant full light when turned on.
As with the compact fluorescent versions, these lamps can only be used with the MEM Eaton lamp holders.
