Description
This GU10 spotlight is an LED lamp drawing 3.6W and giving 345 lumens at 3,000K, a warm white close to the yellow light of the halogen spots most homes were fitted with. The pack rates it as a 50W replacement, so a fitting that held a 50W halogen keeps a similar level of light for a fraction of the power. The beam is a 36 degree cone, the narrow end of the GU10 spread, throwing a defined pool rather than a broad wash. It arrives as a box of four bulbs.
GU10 is the standard mains voltage spot cap in UK kitchens, hallways and living rooms, so these go straight into recessed downlights and track heads with no driver or transformer involved. Check the old bulb first: two stubby pins that push in and twist a quarter turn means GU10, and this will fit. A 36 degree beam suits a run of downlights over a worktop, spots aimed at artwork or shelving, and any position where the light should land somewhere specific rather than fill the room. Warm white keeps a kitchen or a sitting room looking soft rather than clinical.
The lamp dims, but the dimmer has to be one rated for LED loads; older halogen dimmers usually have a minimum load well above what these draw, which is what causes flicker or a dead patch at the bottom of the travel. The energy rating is E and the IP rating IP20, the usual figure for an indoor lamp. The pack prints a 15 year lifespan. One unit is a box of four, ordered in multiples of 12 boxes. We also stock the same 3.6W 345lm GU10 in non-dimmable form at 3,000K.

Frequently Asked
Will this fit my existing spotlights?
If the old bulb has two stubby pins that push in and twist a quarter turn to lock, it is a GU10 and this replaces it directly. GU10 runs on mains voltage, so there is no transformer or driver to check.
Does it really work on a dimmer?
Yes, the specification confirms it is dimmable. Use a dimmer rated for LED loads; an older halogen dimmer often has a minimum load higher than four 3.6W lamps together, which shows up as flicker or a dead section at the low end of the dial.
How bright is 345 lumens in practice?
The pack calls it a 50W replacement, so in a downlight it gives light at about the level a 50W halogen spot did. Three or four in a small kitchen ceiling is a typical arrangement for general working light.
What does 3,000K warm white actually look like?
It is a soft, slightly yellow white, warmer than office lighting and close to the halogen tone people are used to. It flatters wood, warm paint colours and skin tones, and suits kitchens, hallways and sitting rooms.
Is a 36 degree beam narrow or wide?
It sits at the narrow end for a GU10 and puts a defined circle of light below the fitting rather than spreading it sideways. That is what you want over a worktop, an island or a piece of artwork.
How many bulbs do I get, and is there a minimum order?
One unit is a box containing four bulbs. The minimum order is 12 boxes, sold in multiples of 12, so the smallest purchase brings 48 lamps in total.
