Description

The JCB 4.9W GU10 LED bulb delivers 345 lumens at 3000K warm white colour temperature, providing a direct replacement for traditional 50W halogen spotlights while using 90% less energy. The GU10 twist-and-lock base fits standard UK spotlight and downlight fittings without requiring additional adapters or modifications.

Designed for fixed-brightness applications in living rooms, bedrooms, hallways and kitchens, the bulb produces a soft warm white light that suits domestic interiors where ambient warmth is preferred over clinical brightness. The 345-lumen output provides sufficient illumination for general room lighting when used in clusters of 3-6 bulbs, or as accent lighting in display cabinets and alcoves when used individually.

The bulb carries a G energy rating under the updated EU energy labelling scale introduced in 2021, reflecting the shift in baseline standards for LED technology. JCB rates the bulb for up to 10 years of typical domestic use based on 2.7 hours per day operation. The non-dimmable design means the bulb should not be paired with dimmer switches, as this can cause flickering or premature failure.

Frequently Asked

Can this bulb be used with a dimmer switch?

No. This is a non-dimmable LED bulb and must not be used with dimmer switches. Pairing it with a dimmer will cause flickering, buzzing or early failure. If you need dimmable GU10 LEDs, search for 'GU10 dimmable' on the Niori site.

What's the equivalent halogen wattage?

This 4.9W LED bulb replaces a 50W halogen spotlight, delivering similar brightness (345 lumens) while using approximately one-tenth of the power. The warm white 3000K colour temperature closely matches traditional halogen tone.

How long does it last?

JCB rates this bulb for up to 10 years based on typical domestic use of 2.7 hours per day. In practice, lifespan depends on usage patterns, operating temperature and mains voltage stability.

Will it fit my existing spotlight fittings?

Yes, if your existing fittings use GU10 bulbs. The GU10 base is the standard UK twist-and-lock spotlight fitting. Simply remove the old halogen bulb by twisting anti-clockwise and insert this LED bulb by aligning the pins and twisting clockwise until it locks.
