JCB LED GU10 Bulb, 3W, 250 Lumen, 4000K Cool White

This JCB LED GU10 bulb gives 250 lumens in a 4000K cool white from just 3W, roughly a 35W halogen equivalent, with a wide 100° beam angle that spreads light further than a typical narrow GU10 spot. It's a non-dimmable, mains-voltage bulb that's a simple drop-in replacement for old halogen GU10 spotlights, giving a bright, neutral white light with an energy rating of F.

Key features

• 250 lumens

• Wide 100° beam angle
• Non-dimmable

What this bulb is best for

The 4000K cool white tone sits between a warm living-room glow and a stark daylight white, making it a versatile choice for kitchens, hallways, home offices and utility rooms. Its wide 100° beam spreads light over a larger area than a narrow 36° spot, so it can work well where you want one or two bulbs to cover more of a room rather than a tight pool of light.

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 JCB 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 JCB GU10 bulb dimmable?

No, this is a standard non-dimmable spotlight designed for straightforward on/off use.

What does the wide 100° beam angle mean in practice?

A 100° beam spreads light over a much wider area than the 36° narrow spot common on most GU10 bulbs, so it behaves more like a small floodlight - useful where you want broader coverage from fewer fittings rather than a tight, focused beam.

Is 4000K warm or cool?

4000K sits in the middle of the scale - cooler and whiter than the 2700-3000K warm white of a traditional bulb, but not as stark as 6500K daylight, which makes it a practical everyday white for kitchens and hallways.

How long do JCB LED GU10 bulbs typically last?

JCB doesn't publish an exact hours rating for this specific model, but LED GU10 bulbs in this class are typically rated for 15,000 hours or more of use, in line with the wider LED GU10 market.
