• Retrofit and maintenance replacement – Drop-in replacement for compatible 2-pin CFL fixtures. Confirm base type, wattage, and ballast compatibility before ordering.

Replacing Your Current 2-Pin CFL?

• Base type — confirm 2-pin vs 4-pin: This lamp has a G23 2-Pin 2-pin base. 2-pin and 4-pin lamps are not electrically or physically interchangeable even at identical wattages. Check your fixture socket.
• G23 2-Pin base — verify socket type: Confirm your fixture uses G23 2-Pin sockets. G23 and GX23 are different pin spacings — verify the exact designation with your fixture documentation.
• Ballast compatibility: Requires a compatible external preheat magnetic ballast with integral starter. Verify your ballast is rated for this exact wattage and base type. Electronic ballasts may not be compatible with this 2-pin design.
• Wattage — 9W: Confirm your ballast and fixture are rated for 9W.
• Dimmable — No: This lamp is non-dimmable. Do not install on a dimmer circuit.
• Do not use with incompatible ballasts: Lamp performance and life are significantly affected by ballast type. Use only compatible ballasts as specified by the lamp manufacturer.
