Description
This is a 13W LED replacement for the four pin GX24q compact fluorescent lamp, built in the PLT/E shape with four slim tube legs rising from a square white base. The pack rates it at 1780 lumens and prints a 42W replacement figure beside it. Light output is cool white at 4000K, a crisp neutral white that keeps paperwork, signage and stock looking clean rather than yellowed. Check the old lamp before you order: GX24q is the four pin base, and it does not swap with the two pin GX24d version.
Read the pack before this one goes in. Energizer prints a warning that the lamp is not compatible with an electronic ballast, that the ballast must be removed and the fitting rewired direct to mains, and that the work must be carried out by a qualified electrician to BS7671. That makes it a lamp for a planned refit rather than a straight swap, worth knowing if you are working through a run of ceiling fittings in an office, a corridor, a stairwell or a shop floor. Once the wiring is done, an LED source reaches full output the moment it is switched on, with none of the slow warm up a compact fluorescent tube gives you on a cold morning.
There is no dimming here: the specification lists the lamp as non dimmable and the pack carries the non dimmable icon, so put it on a plain switched circuit. The energy label reads class D, and the pack prints a 30,000 hour lifespan. Each unit is one boxed bulb, and the minimum order is 10, sold in multiples of 10, which suits stocking a building rather than chasing one failed lamp. It sits alongside our wider range of LED PL replacements in 2G11 PLL and 2G7 PLS fittings, also in cool white 4000K, if other fittings on the same site take a different pin base.

Frequently Asked
Will this drop straight into my existing GX24q fitting?
Mechanically the four pin GX24q base matches, but electrically it will not. The pack states the lamp is not compatible with an electronic ballast, so the ballast has to be removed and the fitting wired direct to mains by a qualified electrician.
What does 4000K cool white actually look like?
It is a crisp neutral white, noticeably whiter than the yellow cast of a 2700K lamp and calmer than a blue leaning 6500K daylight tube. It suits working areas, corridors and display lighting.
Can I put it on a dimmer?
No. The specification lists the lamp as non dimmable and the pack carries the non dimmable icon, so give it a plain switched on and off circuit rather than a dimming one.
How much light does 13W give me here?
The pack rates the lamp at 1780 lumens and gives 42W as the replacement figure, so it is aimed at a 42W four pin compact fluorescent lamp while drawing 13W at the fitting.
Is a protection rating given for this lamp?
No IP rating appears in the specification or on the pack, so treat the lamp as unrated and keep it to dry, protected indoor positions within an enclosed fitting.
How many do I have to buy?
The minimum order is 10 and they are sold in multiples of 10. Each unit is one boxed bulb, so an order of 10 gives you ten lamps.
