Description

The Energizer 4.2W GU10 is a dimmable LED spotlight bulb rated at 450 lumens output with a 3000K warm white colour temperature. The GU10 twist-and-lock base fits standard UK downlight fittings and ceiling spotlights without requiring an adapter or transformer. At 4.2W power draw, the bulb replaces a 40W halogen equivalent while consuming approximately 90% less energy.

Designed for residential and commercial downlighting where variable brightness is needed, the bulb works with most leading-edge and trailing-edge dimmer switches. Dimming range runs from approximately 10% to 100% brightness depending on the dimmer model, allowing the light level to be adjusted from subtle accent lighting to full task brightness. The 3000K warm white tone suits living rooms, dining areas, bedrooms and hospitality settings where a softer, less clinical light is preferred over cooler daylight tones.

The rated 15-year lifespan assumes 3 hours
