Description

The Energizer 4.8W GU10 LED bulb delivers 450 lumens of cool white light at 4000K through a 36° beam angle, designed as a direct replacement for 60W halogen spotlights. The GU10 twist-and-lock base fits standard UK downlight and spotlight fixtures, and the bulb operates on mains 230V without requiring a transformer.

Intended for kitchens, bathrooms, utility rooms, home offices and retail displays where bright, neutral task lighting is needed, the 4000K colour temperature sits between warm white (2700-3000K) and daylight (5000K+), providing clarity without the harshness of full daylight bulbs. The 36° narrow beam angle concentrates light output into a defined pool rather than spreading it diffusely, making the bulb effective for highlighting worktops, directing light onto bathroom mirrors, or accent lighting onto feature walls.

The non-dimmable LED driver inside the bulb provides stable, flicker-free output at full brightness from switch-on. At 4.8W power draw, the bulb consumes 92% less energy than the 60W halogen it replaces, and the rated 15-year lifespan (based on 3 hours daily use) reduces replacement frequency compared to halogen bulbs that typically last 2,000-3,000 hours. The bulb carries an Energy Rating of E under the revised 2021 EU energy label scale.

Frequently Asked

Is this bulb dimmable?

No. The Energizer 4.8W GU10 is non-dimmable and should not be used with dimmer switches. Attempting to dim a non-dimmable LED can cause flickering, buzzing or premature failure.

What halogen wattage does this replace?

This 4.8W LED bulb replaces a 60W halogen GU10, delivering comparable light output (450 lumens) at a fraction of the energy consumption.

What does 4000K cool white look like?

4000K is a neutral white light that sits between warm white (yellowish, 2700-3000K) and daylight (bluish, 5000K+). It provides clear visibility for task work without the warmth of traditional incandescent bulbs or the clinical feel of full daylight.

Will this fit my existing GU10 downlights?

Yes. The GU10 base is a standard UK spotlight fitting with a twist-and-lock mechanism. This bulb fits any mains-voltage GU10 socket without requiring a transformer or adapter.
