Energizer 13W LED PLT/E 4-Pin Bulb GX24q - Cool White 4000K

The Energizer 13W LED PLT/E is a four-pin GX24q replacement bulb designed to retrofit compact fluorescent lamps in commercial downlights, bulkheads and recessed ceiling fixtures. The twin-tube LED configuration delivers 1780 lumens at 4000K cool white, replacing legacy 42W CFL equivalents while cutting energy consumption by approximately 70%. The four-pin GX24q base allows direct plug-in installation without rewiring or ballast modification in most compatible fixtures.

Suited to commercial environments where consistent, cool-toned light is required, the bulb works in office open-plan spaces, retail fitting rooms, washrooms, corridors and stairwells. The 4000K colour temperature sits between neutral white and daylight, giving a crisp output that supports task work and detailed inspection without the harshness of 6000K+ daylight bulbs. The instant start-up eliminates the warm-up delay common to fluorescent tubes, and the solid-state LED design runs cooler than CFL equivalents, reducing HVAC demand in enclosed ceiling voids.

The PLS (parallel lamp shape) form factor orientates the twin tubes vertically, distributing light evenly when mounted horizontally in a downlight housing. The bulb is non-dimmable, which simplifies installation in switch-controlled circuits and avoids dimmer compatibility issues. Energy rating D reflects the bulb's improved lumen-per-watt performance against older CFL technology, though LED technology has since moved to higher-efficiency ratings in newer product generations. The 13W draw allows multiple bulbs on a single circuit without overloading typical commercial ring mains.

Is this a direct retrofit for GX24q CFL bulbs?

Yes. The four-pin GX24q base fits directly into fixtures designed for compact fluorescent lamps with the same base type. In most cases, no ballast removal or rewiring is needed, though some older magnetic-ballast fixtures may require bypass for optimal performance.

What colour temperature is 4000K?

4000K sits in the cool white range, between neutral white (3500K) and daylight (5000K+). It produces a crisp, clean light tone suited to workspaces, retail and commercial environments where clarity is needed without the warmth of domestic lighting.

Can this bulb be used with a dimmer switch?

No. The bulb is non-dimmable and will not function correctly on dimmer circuits. Use only with standard on/off switching.

What is the equivalent wattage to CFL?

This 13W LED replaces a 42W CFL lamp, delivering similar lumen output (1780lm) while using approximately 70% less energy. The energy rating of D reflects the improvement over legacy fluorescent technology.
