Description

The JCB 4.9W GU10 LED bulb delivers 345 lumens at 4000K cool white colour temperature, providing a crisp neutral light suited to task-focused environments. The GU10 twin-pin base fits standard UK spotlight fittings and recessed downlights without requiring an adapter. At 4.9W consumption the bulb replaces a traditional 50W halogen GU10 while drawing approximately 90% less power.

Designed for kitchens, bathrooms, utility rooms, home offices and retail display areas where clarity and colour accuracy matter more than warmth, the 4000K output sits between warm white (2700-3000K) and daylight (5000K+). The 100° beam angle provides wide coverage from a single fitting, reducing the number of bulbs needed to light a worktop, vanity mirror or display shelf compared to narrow-beam alternatives.

The bulb measures 50mm diameter by 57mm length, matching the physical footprint of most halogen GU10s so it sits flush in existing fittings. The spot lamp shape directs light forward rather than dispersing it in all directions. JCB rates the bulb for up to 10,000 hours of use — approximately 10 years at typical residential usage of 2-3 hours per day. This model is non-dimmable and carries an Energy Rating of G under current UK labelling.

Frequently Asked

Is this bulb dimmable?

No. This JCB GU10 is non-dimmable and should not be used with dimmer switches. Installing a non-dimmable LED on a dimmer circuit can cause flickering, buzzing or early failure.

What's the difference between 4000K and warm white bulbs?

4000K cool white produces a neutral, slightly blue-toned light similar to overcast daylight. Warm white bulbs (2700-3000K) produce a yellow-toned glow closer to traditional incandescent or halogen light. 4000K suits task lighting in kitchens and bathrooms; warm white suits living rooms and bedrooms.

Will this fit my existing GU10 spotlight fittings?

Yes. The GU10 twin-pin base is a UK standard fitting. This bulb measures 50mm diameter by 57mm length, matching the footprint of most halogen GU10s, so it fits flush in ceiling downlights, track spots and wall-mounted GU10 fittings.

How long does the bulb last?

JCB rates this bulb for up to 10,000 hours. At typical residential usage of 2-3 hours per day that equates to approximately 10 years before needing replacement.
