Description

The Energizer 3.6W GU10 is a dimmable LED spotlight bulb delivering 345 lumens of 3000K warm white light through a 36° narrow beam angle. The GU10 twist-and-lock base fits standard UK mains voltage spotlight fittings without needing a transformer, replacing 50W halogen bulbs while consuming 93% less energy.

Designed for recessed downlights, track lighting and adjustable spotlight fittings in living rooms, kitchens, hallways and retail spaces, the narrow 36° beam concentrates light onto specific surfaces rather than flooding an entire room. The dimmable function allows brightness adjustment from full 345-lumen output down to low-level mood lighting, compatible with most leading-edge and trailing-edge dimmer switches.

The bulb measures 50mm diameter by 54mm height, matching the compact footprint of traditional halogen GU10s so it fits existing luminaire housings without modification. Energizer rates the LED module at 15 years based on average domestic use of 2.7 hours per day, reducing the frequency of bulb changes in high or hard-to-reach fittings. The 3000K colour temperature sits in the warm white spectrum, rendering reds and yellows naturally while avoiding the blue-tinged cast of cooler daylight LEDs.

Frequently Asked

Is this bulb compatible with dimmer switches?

Yes. The Energizer GU10 is dimmable and works with most leading-edge and trailing-edge dimmer switches. If you experience flickering at low brightness levels, check that your dimmer is rated for LED loads rather than halogen-only.

What halogen wattage does this replace?

This 3.6W LED replaces a 50W halogen GU10 while delivering 345 lumens. The energy saving is approximately 93%, reducing running costs and heat output in recessed downlight fittings.

What's the beam angle and where does it work best?

The 36° narrow beam angle concentrates light into a focused cone, making it suitable for accent lighting, highlighting artwork, task lighting over kitchen worktops, and directional spotlights in track systems. For general room lighting, wider beam angles (60°+) are typically preferred.

Does it fit standard GU10 luminaires?

Yes. The 50mm diameter and 54mm height match the dimensions of halogen GU10 bulbs, so it fits existing downlight housings, track heads and spotlight fittings without modification. The GU10 base requires mains voltage (230V) and does not need a transformer.
