Description
The Energizer 4.8W GU10 LED bulb delivers 450 lumens at 6500K daylight colour temperature through a 36° narrow beam angle. The bulb draws 4.8W on 230V mains and replaces traditional 60W halogen GU10s, reducing energy consumption by approximately 92% while providing comparable light output in a focused beam pattern.
Designed for directional downlighting in kitchens, bathrooms, home offices and commercial spaces where bright, cool-toned task lighting is needed, the 6500K colour temperature produces a crisp white light that matches natural midday outdoor light. The 36° beam angle concentrates light into a defined pool, making it suitable for spotlight fittings, track lighting and recessed downlights where focused illumination is required rather than broad ambient wash.
The bulb is non-dimmable and provides steady output without flicker across its rated 15-year lifespan under typical domestic use patterns. The GU10 two-pin twist-and-lock base fits standard UK mains-voltage spotlight fittings without requiring a transformer. At 50mm diameter and 54mm height, the bulb sits flush or slightly recessed in most GU10 downlight housings.
Energy rated E under current UK regulations, the bulb balances output and efficiency for high-use areas where frequent replacement would be inconvenient. The 30g weight and compact dimensions make it suitable for ceiling-mounted fittings where heavier bulbs might stress fixture springs over time.

Frequently Asked
Is this bulb suitable for bathrooms?
The bulb operates on 230V mains and has no stated IP rating, so it should only be used in bathroom zones where mains-voltage fittings are permitted and where water contact is unlikely. Check your specific downlight housing for its IP rating and zone suitability.
What does 6500K daylight colour temperature look like?
6500K produces a crisp, cool white light similar to midday outdoor light or overcast sky conditions. It appears noticeably bluer and brighter than 3000K warm white, making it suited to task-focused environments like workshops, offices and kitchens where colour accuracy and alertness matter.
Can this bulb be used with a dimmer switch?
No. This bulb is non-dimmable and will not function correctly with dimmer switches. Attempting to use it on a dimmed circuit may cause flicker, reduced lifespan or immediate failure.
How does the 36° beam angle compare to wider-beam GU10s?
A 36° beam creates a defined spotlight effect with a concentrated pool of light and sharper edges. Wider-beam GU10s (typically 60-120°) provide softer, more diffused coverage. The 36° angle suits accent lighting, artwork illumination and task areas where you want directed light rather than broad ambient fill.
