Description
This is a GU10 LED spotlight bulb that draws 3.1W and gives 250 lumens of warm white light at 3,000K. The cap is the twist and lock GU10 type, with two pins that twist a quarter turn into the holder, so it goes straight into the mains voltage downlights and track spots that take a GU10 without any transformer. The body is white with a frosted face, which softens the light rather than showing the individual diodes behind it. The pack rates it as a replacement for a 35W conventional spot, and each box holds two bulbs.
Warm white at 3,000K sits at the friendly end of the white scale, a light with a little cream in it and close to the glow of the halogen spots most people are replacing. It suits a kitchen ceiling, a living room, a landing or a hallway. The beam is wide rather than tight, so it washes a worktop or a run of shelving fairly evenly instead of dropping a hard circle of light onto the floor. At 250 lumens one lamp on its own is modest, so these earn their keep in ceilings running several spots together, where the combined output lights the room.
Check the circuit before you order: these are not dimmable, so they want a plain switched supply. On a dimmer they can flicker or buzz, and they may fail well short of their rated life. The energy label rates them G, at 4kWh per 1,000 hours of use, and the pack prints a 10 year lamp life. They are rated IP20, so keep them to dry indoor fittings. Each box holds two bulbs and the minimum order is six boxes, sold in multiples of six, which suits relamping a whole ceiling at once. These sit alongside our wider range of LED bulbs in B15, B22 and E27 fittings, in warm white, cool white and daylight.

Frequently Asked
Will these fit my existing GU10 downlights?
Yes, if the old bulb has two flat pins that twist a quarter turn to lock. That is the mains voltage GU10 cap, and it needs no transformer or driver behind it.
Can I use them on a dimmer switch?
No. The specification states they are not dimmable, so they need a plain on and off switched circuit. On a dimmer they may flicker, buzz or fail early.
How bright is 250 lumens in real terms?
The pack rates each lamp as a replacement for a 35W conventional spot, so it is a gentle output best used where several spots share the ceiling.
What does warm white 3,000K actually look like?
It is a soft, slightly creamy white rather than a blue or clinical one, close to the tone of the halogen spots many people are swapping out.
How many bulbs do I get, and how many boxes must I buy?
Each box contains two bulbs. The minimum order is six boxes, sold in multiples of six, so the smallest order gives you twelve bulbs in total.
How long should they last and what will they cost to run?
The pack prints a 10 year lamp life, and the energy label gives an G rating with a figure of 4kWh per 1,000 hours of use.
