TCP LED GU10 Bulb, 250 Lumen, 2700K Warm White, Pack of 4

This TCP LED GU10 spotlight bulb delivers a soft 250 lumen output in a warm 2700K white, in a glass-bodied bulb on the standard 36° GU10 twist-and-lock base. At 3.3W each (roughly a 20W halogen equivalent), it's a low-cost, energy-saving swap for older halogen GU10 downlights, and the warm white colour temperature suits relaxed living spaces where a cosy glow matters more than clinical brightness. This listing is for a pack of 4 bulbs.

• 250 lumens per bulb
• 3.3W LED (approx. 20W halogen equivalent)

What this bulb is best for

The warm 2700K tone is a natural match for living rooms, bedrooms and dining areas, where a soft, welcoming light is more comfortable than a stark white. It also works well as accent lighting in hallways or snugs, anywhere you want the room to feel calm rather than clinical.

How to fit it

1. Turn off the power at the switch before you start.
2. If you're replacing an old bulb, let it cool down fully first.
3. Twist the old bulb anticlockwise a quarter turn and pull it free.
4. Push the new TCP GU10 bulb in and twist clockwise until it clicks into place.
5. Restore power at the switch.

GU10 bulbs run directly on mains voltage, so there's no transformer or separate driver to fit - it's a like-for-like swap in your existing fitting.

Frequently asked questions

Is this TCP 250 lumen warm white bulb dimmable?

This pack is a standard on/off LED spotlight rather than a dimmable model. If you'd like a dimmable warm white GU10, see our TCP 345 lumen 2700K dimmable bulbs linked below.

Will this warm white bulb suit my living room?

Yes - 2700K is the same warm tone as a traditional filament or halogen bulb, so it's a safe choice for living rooms, bedrooms and other spaces where you want a relaxed, homely feel.

Is a 4-pack enough for one room?

A pack of four is a practical size for a single downlight circuit, such as a living room ceiling with four spotlights, without buying more than you need.

What's the difference between this and the 6500K version?

Both use the same 250 lumen, 3.3W bulb - the only difference is colour temperature. This one is 2700K warm white for relaxed rooms; our 6500K version gives a brighter, whiter daylight tone for kitchens and workspaces.
