The AD E40 porcelain lamp holder is a barrel-type fitting designed for large screw-base (E40 / Goliath) lamps. Its 5/8" barrel mount allows direct attachment to standard conduit or pendant rod, and the porcelain body withstands the heat generated by high-wattage E40 lamps in industrial, commercial, and outdoor enclosed luminaires.

Rated at 6A and 500V, it meets the demands of high-intensity discharge and other high-power E40 light sources. The porcelain construction provides electrical insulation and thermal stability that plastic holders cannot match at elevated operating temperatures.
