Description
This is a 6W LED lamp on a GX24q four pin cap, made to take the place of a 4 pin compact fluorescent PL lamp in the PLT/E shape. Four flat blade pins sit beneath a white moulded base, and the light comes from a cluster of short upright tubes above it, so the lamp keeps the squat outline the original had. It gives 840 lumens, which the pack rates as the equal of an 18W compact fluorescent. The colour is 4000K cool white, a neutral white with no yellow in it, which keeps signage, paintwork and printed matter reading true.
Four pin PL lamps of this size belong to commercial fittings more than domestic ones. They sit in recessed downlights and wall washers, in stairwell and corridor bulkheads, and in the enclosed ceiling fittings used through offices, shops, hotel landings and communal areas. Cool white suits those places because it stays crisp late in the day and matches the neighbouring fluorescent fittings rather than reading warm beside them. Check the cap on the lamp you are removing: GX24q carries four pins, GX24d carries two, and a two pin holder will not take this one.
One thing to settle before ordering. The pack states that the lamp is not compatible with an electronic ballast, that the ballast must be removed and the fitting rewired to run direct from the mains, and that installation is for a qualified electrician working to BS7671. It is not dimmable, so keep it off dimmer circuits. The energy rating is D, and the pack prints a 30,000 hour lifespan. Each box holds one lamp, and the minimum order is 10, sold in multiples of 10. We also list 2G11 PLL and 2G7 PLS lamps in the same 4000K cool white.

Frequently Asked
Will this lamp fit a two pin GX24d holder?
No. A GX24q holder takes four pins in the base and a GX24d holder takes two, so count the pins on the lamp you are replacing before ordering.
Does the ballast have to come out?
Yes. The pack states that the lamp is not compatible with an electronic ballast, that the ballast is removed and the fitting rewired to run direct from the mains, and that the work is for a qualified electrician to BS7671.
What does 4000K cool white actually look like?
A neutral white that reads crisp rather than warm, without the blue edge of a 6500K daylight lamp, and an easy match for existing fluorescent fittings alongside it.
Can I run it on a dimmer?
No, this lamp is not dimmable. On a dimmer circuit it may flicker, buzz or fail early, so wire it to a plain switched circuit instead.
Is an IP rating given for this lamp?
Energizer prints no IP rating for it, so we quote none. Treat the lamp as unrated and keep it to dry indoor fittings.
How many lamps do I receive?
Each box holds a single lamp. The minimum order on this listing is 10 units, sold in multiples of 10, so ten boxes arrive.
