Plug-In CFL for General Lighting

This GE plug-in compact fluorescent lamp uses a GX24Q-4 four-pin base and draws 42 watts. It delivers 2690 lumens of soft white light at 2700 kelvin with a colour rendering index of 82.0. The bulb is suited for general-purpose fixtures that accept a preheat start type and ballast-dependent operation.

T4 Shape with Four-Pin Base

The T4 tube measures 5 1/2 inches overall and fits recessed or surface-mounted downlights designed for the GX24Q-4 connector. Because the lamp is ballast dependent, it requires a compatible electronic ballast in the fixture. Shatter-resistant coating is not included, so handle with care during installation.

Rated Life and Thermal Behaviour

Rated life is 17000 hours under normal switching cycles. The preheat start method provides a brief warm-up before full brightness is reached. Power draw remains steady at 42 watts once the lamp is operating, and the compact fluorescent design runs cooler than incandescent equivalents in the same fixture.

Questions about this item

What wattage ballast is required for the GX24Q-4 base?

The bulb draws 42 W and is ballast dependent; the fixture must provide a compatible 42 W ballast for the GX24Q-4 socket.

What clearance does the 5 1/2 in overall length need?

The T4 tube measures 5 1/2 in end to end, so the recessed can or fixture must accept that full length.

How is the 4-pin base installed and what is the common error?

Align the four pins with the GX24Q-4 socket keyways and press straight in; forcing it without aligning the keyways bends the pins.
