Description

The Energizer 9W LED PLT/E is a 4-pin retrofit bulb with a GX24q base, designed to replace 26W compact fluorescent lamps in commercial downlights, utility fittings and shared-area luminaires. The bulb delivers 1260 lumens at 4000K cool white, drawing just 9W on 230V mains. The twin-tube PLS form factor mirrors traditional CFL geometry, allowing direct replacement without modifying existing lamp holders or control gear.

Built for commercial installation, the bulb suits retail environments, office corridors, public washrooms and utility rooms where consistent cool white light is required for task visibility and colour rendering. The instant-on LED provides full 1260 lumens from switch-on with no warm-up period or flicker, and maintains stable output throughout its rated lifespan. The GX24q 4-pin base locks into compatible lamp holders by rotating the bulb 90 degrees after insertion.

The LED construction is mercury-free and carries Energy Rating D under current regulations, offering lower running costs and reduced disposal requirements compared to the CFL lamps it replaces. The 4000K colour temperature sits between warm and daylight tones, delivering a neutral white that balances clarity with comfort. Non-dimmable — the bulb operates at full output only and is not compatible with dimmer switches or phase-control circuits.

Frequently Asked

What does the GX24q base fit?

The GX24q is a 4-pin base used in PLT/E and some downlight fittings. The bulb inserts into the lamp holder and rotates 90 degrees to lock in place. Check your existing bulb base before ordering — GX24q-4 and GX24q-3 bases differ in pin spacing.

Can this bulb be used with a dimmer?

No. The bulb is non-dimmable and operates at full output only. Installing it on a dimmer circuit may cause flicker, hum or premature failure. If dimming is required, a dimmable GX24q LED must be used instead.

What colour temperature is 4000K?

4000K is cool white, sitting between warm white (2700-3000K) and daylight (5000K+). It provides a neutral, slightly crisp light that enhances visibility in task environments without the warmth of domestic lighting or the harshness of daylight tones.

How does the 9W output compare to a CFL?

The 9W LED produces 1260 lumens, matching the output of a typical 26W compact fluorescent lamp while drawing approximately 65% less power. Running costs drop in proportion to the wattage saving.
