Energizer 3.6W GU10 Dimmable LED Bulb - Daylight 6500K (4 Pack)

The Energizer GU10 is a 3.6W dimmable LED bulb delivering 345 lumens of 6500K daylight-white light through a 36-degree beam angle. This four-pack provides replacement bulbs for multiple fixtures in one purchase, with each bulb measuring 50mm diameter by 54mm height and fitting standard GU10 twist-and-lock lamp holders.

Designed for kitchens, offices, retail displays and task lighting where colour accuracy and clarity matter, the 6500K colour temperature produces a bright, cool-white light that renders colours without the warm yellow cast of lower colour temperatures. The narrow 36-degree beam concentrates light into a defined spot, making these bulbs suited to recessed downlights, track lighting and directional accent fixtures rather than broad ambient wash lighting.

The dimmable function allows brightness adjustment from full 345 lumens down to lower levels depending on the time of day or task requirements. Dimmer compatibility varies by dimmer model — leading-edge dimmers typically work better with LED bulbs than trailing-edge models. Each bulb in the pack carries a 15-year rated lifespan based on average household use patterns, reducing replacement frequency compared to halogen GU10s.

At 3.6W per bulb, the four-pack draws 14.4W total when all four are in use, compared to approximately 200W for four equivalent 50W halogen GU10 bulbs. The Energy Rating E reflects current EU energy labelling standards for LED bulbs.

What does 6500K daylight mean?

6500K is a cool, bright white light similar to midday sunlight on an overcast day. It renders colours accurately without the warm yellow tone of 2700K-3000K bulbs, making it useful in kitchens, offices and retail spaces where you need to see fine detail or match colours precisely.

Are these compatible with all dimmer switches?

These bulbs are dimmable, but compatibility depends on your specific dimmer model. Leading-edge dimmers designed for LED loads generally work better than older trailing-edge dimmers designed for halogen bulbs. If your dimmer causes flickering or won't dim smoothly, you may need to replace the dimmer with an LED-compatible model.

How does the 36-degree beam angle affect placement?

A 36-degree beam creates a concentrated spot of light rather than wide ambient coverage. These bulbs work well in recessed downlights positioned 1-1.5m apart to avoid dark patches between fixtures. For broader wash lighting, bulbs with 60-120 degree beam angles are more appropriate.

Can these replace 50W halogen GU10 bulbs?

At 345 lumens per bulb, these deliver roughly the same light output as a 35-40W halogen GU10, not a full 50W halogen (which typically produces 400-450 lumens). If your existing halogen GU10s are rated 50W and you need the same brightness, consider a higher-output LED bulb in the 5-6W range delivering 400+ lumens.
