Description

The Energizer 3.6W GU10 LED bulb replaces a 50W halogen spotlight whilst consuming 93% less energy, delivering 345 lumens of warm white 3000K light through a 36° narrow beam angle. The GU10 base fits standard UK mains-voltage spotlight fittings without requiring a transformer, making it a direct halogen replacement for recessed downlights, track lighting and adjustable spotlights.

Designed for fixed-brightness applications in living rooms, bedrooms, kitchens and hallways, the bulb produces a warm white output comparable to traditional incandescent lighting. The 36° beam angle concentrates light into a defined pool rather than flooding a room, making it well-suited to accent lighting over artwork, highlighting architectural features, or task lighting in kitchens where directional light is needed over worktops. The non-dimmable design maintains consistent output across the 15-year rated lifespan.

The 50mm diameter and 54mm height match standard GU10 halogen dimensions, ensuring the bulb sits flush within recessed housings and does not protrude beyond the ceiling line. At 30g the LED weighs slightly less than the halogen it replaces, reducing strain on spring-clip lamp holders. The warm white 3000K colour temperature renders reds and yellows naturally whilst providing enough clarity for reading and detailed tasks.

Frequently Asked

Is this bulb dimmable?

No. This is a non-dimmable GU10 LED bulb. Installing it in a dimmer-controlled circuit may cause flickering or damage the bulb. If you need dimmable GU10s, search for dimmable variants in the Niori bulb catalogue.

What halogen wattage does this replace?

This 3.6W LED replaces a 50W halogen GU10, delivering comparable light output (345 lumens) at a fraction of the energy consumption. The beam angle is narrower than some halogens at 36°, concentrating light rather than flooding it.

Does it fit standard GU10 fittings?

Yes. The bulb uses the standard GU10 twist-and-lock base and matches halogen dimensions at 50mm diameter and 54mm height. It fits directly into mains-voltage GU10 lamp holders without requiring a transformer or adaptor.

What is the expected lifespan?

Energizer rates this bulb at 15 years under typical domestic use (approximately 13,500 hours). Actual lifespan depends on usage patterns and operating environment, but LED technology typically outlasts halogen by 10-15x.
