Description

The JCB 4.9W GU10 LED bulb is a direct replacement for 50W halogen spotlights, delivering 345 lumens at 3000K warm white from a standard GU10 twist-lock base. Each bulb in the 4-pack measures 50mm diameter by 57mm height and uses 90% less energy than the halogen equivalent it replaces. The bulbs are non-dimmable and rated Energy Rating G under current UK energy labelling.

Designed for downlights, track lighting, and recessed ceiling fittings across residential and commercial installations, the bulbs fit any GU10 lampholder without adapters or modifications. The 3000K colour temperature produces a warm white glow comparable to traditional halogen, making the transition visually seamless in living rooms, bedrooms, hallway downlighters, and kitchen ceiling spots. The 4-pack format allows you to replace a full room's worth of bulbs in one go or keep spares on hand.

Each bulb weighs 35g (0.14kg for the 4-pack) and has a rated lifespan of 10,000 hours under typical domestic use — approximately 10 years at 3 hours per day. The spot beam angle concentrates light downwards rather than spreading it wide, matching the directional output of the halogen bulbs these replace. The non-dimmable circuit means they should only be used on standard on/off switches, not variable dimmer controls.

Frequently Asked

Can these bulbs be used with dimmer switches?

No. These are non-dimmable LED bulbs and will not work correctly on dimmer circuits. Attempting to dim them may cause flickering, buzzing, or premature failure. Use them only with standard on/off switches.

What halogen wattage do these replace?

Each 4.9W LED bulb replaces a 50W halogen GU10 bulb, delivering comparable brightness at 345 lumens while using 90% less energy.

How long do these bulbs last?

JCB rates these bulbs at 10,000 hours typical lifespan. At 3 hours per day average use, that works out to approximately 10 years before replacement is needed.

Will the light colour match my existing halogen bulbs?

The 3000K warm white colour temperature is very close to standard halogen output, so the transition should be visually seamless. If you're replacing a mix of halogen and LED in the same room, you may notice a slight difference until all bulbs are replaced.
