GU10 LED Spotlight Bulb 2W 360lm Non-Dimmable - Cool White 4000K

This is a GU10 spotlight bulb with an LED light engine, drawing 2W and giving 360 lumens at 4000K. That colour temperature is cool white: a crisp, neutral light with no yellow in it, closer to daylight than to the warm glow of an old halogen. The pack rates the bulb as a 50W replacement and prints the brightness as 360 lumens in a narrow cone, so the light is concentrated rather than spread flat across a ceiling. It carries an A energy rating on the current scale, where A is the top band.

GU10 is the twist and lock cap used in most mains voltage downlights, track heads and spotlight bars, so this goes straight into a fitting that already takes a GU10 without a transformer or driver. A narrow cone suits places where you want the light to land somewhere in particular: over a worktop, down a run of shelves, onto artwork or a splashback, or along a row of track heads in a hallway. Cool white at 4000K reads as clean and neutral, which is why it tends to work better in kitchens, utility rooms, garages and home offices than in a sitting room, where most people prefer a warmer 2700K or 3000K.

There is no dimming here: the pack marks the bulb as non dimmable, so pair it with a plain on and off switch. Running a non dimmable lamp on an existing dimmer circuit can cause flicker or buzzing, so check the switch before you order. The pack prints a 50 year lifespan. Each box holds one bulb, and the minimum order is 12, sold in multiples of 12. We stock other GU10 LED bulbs alongside it, including a 3.6W version in warm white 3000K.

Will this fit my existing downlights?

If the old bulb has two stubby pins that twist and lock a quarter turn into the holder, it is a GU10 and this will fit. GU10 runs on mains voltage, so no transformer or driver is needed.

Can I use it on a dimmer switch?

No. The pack marks this bulb as non dimmable, so it needs a standard on and off switch. On a dimmer circuit you may get flicker, buzzing or a shorter working life from the lamp.

How bright is 2W against the halogen spot it replaces?

It gives 360 lumens, and the pack rates that as a 50W replacement. Because the light is thrown in a narrow cone rather than spread widely, it reads as bright directly under the fitting.

What does 4000K cool white actually look like?

It is a clean, neutral white with no amber cast, useful where you are working or looking closely at something. If you want a softer, yellower light for a living room, choose 2700K or 3000K instead.

How many bulbs do I receive?

Each box contains one bulb. The minimum order on this listing is 12 boxes, sold in multiples of 12, so you receive 12 single bulbs on the smallest order.
