Description

The Energizer GU10 is a 3.6W LED spotlight bulb delivering 345 lumens at 3000K warm white through a 36° beam angle. The clear glass front allows the internal LED array to be visible when unlit, giving the bulb a traditional halogen appearance while running on LED efficiency. The GU10 twist-lock base fits standard mains-voltage spotlight fittings without requiring a transformer.

Designed for recessed downlights, track lighting and directional accent fittings in kitchens, hallways, retail displays and hospitality spaces, the 36° beam provides focused illumination suitable for highlighting surfaces or objects rather than wide-area flood lighting. At 3.6W the bulb replaces a 50W halogen spotlight, reducing energy draw by over 90% while maintaining comparable light output. The non-dimmable design ensures consistent brightness on standard switching.

The bulb measures 50mm diameter by 54mm length, fitting flush into standard recessed ceiling cans without protruding. At 40g the bulb sits securely in overhead fittings without strain on the GU10 socket. Energizer rates the lifespan at 15 years based on 3 hours daily use, reducing the frequency of replacement in ceiling fittings where access requires ladders or scaffolding. The clear glass front and visible LED components suit modern and industrial interiors where the internal workings of the bulb become part of the aesthetic.

Frequently Asked

Is this bulb dimmable?

No. This Energizer GU10 is non-dimmable and should be used with standard on/off switching only. Attempting to use it with a dimmer switch may cause flickering or damage the bulb.

What halogen wattage does it replace?

This 3.6W LED replaces a 50W halogen GU10 spotlight, providing comparable light output at 345 lumens while drawing significantly less power.

What's the beam angle?

The bulb has a 36° beam angle, producing a focused spotlight effect rather than wide flood lighting. This suits directional accent lighting, display lighting and task lighting where concentrated light is needed on a specific area.

Does it need a transformer?

No. GU10 bulbs run on mains voltage (230V) and twist-lock directly into GU10 sockets. Unlike low-voltage MR16 or GU5.3 bulbs, no transformer is required.
