Description

The JCB 4.9W GU10 LED bulb produces 345 lumens at 3000K warm white from a standard GU10 twist-and-lock base, replacing 50W halogen spotlights with 90% lower energy consumption. The bulb operates on 220-240V mains and is non-dimmable, designed for constant-brightness applications in recessed downlights, track lighting and accent fittings.

Suited to residential living rooms, bedrooms, hallways and commercial retail or hospitality spaces where warm ambient light is preferred over cooler task lighting. The 100° beam angle provides wider coverage than traditional 38° halogen spots, reducing the number of bulbs needed to light a given area. The GU10 base fits directly into standard UK mains-voltage spotlight fittings without requiring a transformer.

The bulb measures 50mm diameter by 57mm height, matching the physical footprint of the halogen bulbs it replaces so there are no clearance issues in recessed housings. The spot-style reflector directs light forward rather than spilling it sideways, maintaining definition in directional lighting schemes. Rated Energy Class G under current EU labelling, the bulb draws 4.9W continuously and carries JCB's standard warranty terms.

Frequently Asked

Is this bulb dimmable?

No. This is a non-dimmable LED bulb and should not be used with dimmer switches. Installing it on a dimmer circuit may cause flickering, buzzing or premature failure. For dimmable GU10 LEDs, search the Niori catalogue for 'GU10 dimmable'.

What's the beam angle and coverage?

The bulb has a 100° beam angle, significantly wider than the 38° typical of older halogen GU10s. This wider spread means fewer bulbs are needed to light a room evenly, but may produce less dramatic accent lighting in directional applications.

Does it fit standard GU10 fittings?

Yes. The GU10 base is a standard UK mains-voltage twist-and-lock fitting. The bulb measures 50mm diameter by 57mm height, the same physical size as the 50W halogen bulbs it replaces, so it fits into existing recessed housings without clearance issues.

How does 345 lumens compare to a halogen?

345 lumens is roughly equivalent to a 50W halogen GU10 in total light output, though the wider beam angle distributes that light differently. If your existing halogens are brighter than 50W, this LED will appear dimmer; if they were 35W, this will appear brighter.
