Mogul-base format, not a two-pin replacement
This model differs from PGZX18 two-pin 315W CDM lamps. A screw base alone does not establish electrical compatibility: match the complete model, ballast specification, socket, and fixture requirements before purchase. Do not install it in a standard HPS or MH system solely because it fits the socket.
Installation and handling
Replacement lamp only; ballast and fixture are not included. Disconnect power and allow the lamp and fixture to cool before replacement. Follow the exact lamp and fixture instructions, including any enclosure requirements.
