Description

The Energizer 3.6W GU10 LED bulb delivers 345 lumens of 6500K daylight-spectrum light through a 36° beam angle, designed as a direct retrofit replacement for 50W halogen GU10 spotlights. The GU10 twist-and-lock base fits standard mains-voltage downlight fittings without requiring transformers or adapters, and the 50mm diameter matches the aperture size of most recessed ceiling fittings.

Intended for task lighting in kitchens, bathrooms, workspaces and retail environments where cooler, brighter light aids visibility, the 6500K colour temperature replicates natural daylight and provides high contrast for detailed work. The 36° narrow beam concentrates light into a defined pool rather than spreading it across a room, making the bulb suitable for accent lighting, directional spotlighting over worktops, or illuminating specific display areas. The non-dimmable circuit simplifies installation in switched-only lighting systems.

The bulb measures 54mm in height and 50mm in diameter, with a rated lifespan of 15 years based on average domestic use of 2.7 hours per day. At 3.6W draw per bulb, a typical kitchen installation with six GU10 fittings would consume 21.6W total compared to 300W with the halogen equivalents. The energy rating of E reflects the lower efficacy of small-format LED spotlights compared to larger bulb formats, but still represents an 86% reduction in energy consumption versus halogen.

Frequently Asked

Is this bulb dimmable?

No. This bulb is non-dimmable and will not function correctly with dimmer switches. Attempting to use it with a dimmer may cause flickering or damage to the bulb circuit.

What colour temperature is 6500K?

6500K is classified as daylight or cool white, producing a crisp, bright light with blue undertones that replicates natural daylight at midday. This is cooler and more clinical than warm white (2700K-3000K) commonly used in living spaces.

Will this fit my existing GU10 downlights?

Yes. The GU10 twist-and-lock base is a standard UK mains-voltage fitting. The bulb fits any GU10 socket without requiring transformers, and the 50mm diameter matches most recessed ceiling downlight apertures.

How does the 36° beam angle affect light spread?

A 36° beam is classified as narrow, concentrating light into a focused pool rather than washing a wide area. This suits accent lighting, task lighting over worktops, or highlighting specific objects, but multiple bulbs are needed to evenly light a larger room.
