Description

The Energizer GU10 LED bulb delivers 345 lumens of warm white light at 3000K from a 3.6W LED chip, replacing traditional 50W halogen GU10s with an energy saving of over 90%. Each bulb in this 4-pack fits standard GU10 twist-and-lock fittings and is rated for mains 230V operation with full dimmer compatibility across most leading dimmer switches.

Designed for recessed downlights, track lighting and spotlight fittings in kitchens, bathrooms, living rooms and retail settings, the 36° beam angle provides focused directional light rather than diffuse ambient spread. The compact 50mm diameter and 54mm height match the footprint of halogen GU10s, so they retrofit directly into existing fittings without adapter rings or modification. Dimming allows light levels to be adjusted from full 345 lumens down to around 10% for late-evening ambience or cinema-room use.

The 15-year lifespan rating assumes 3 hours of daily use, equivalent to approximately 15,000 hours before the LED output degrades below 70% of initial brightness. The warm white 3000K temperature sits between soft white (2700K) and neutral white (4000K), providing a gentle tone that works in both traditional and contemporary interiors without the stark feel of cooler LED temperatures. The four-bulb pack suits multi-lamp installations such as kitchen ceiling grids or hallway downlight runs where consistent colour temperature across multiple fittings matters.

Frequently Asked

Are these compatible with dimmer switches?

Yes, these Energizer GU10 LEDs are rated as dimmable and work with most leading-edge and trailing-edge dimmer switches. If you experience flickering or limited dimming range, the dimmer may need upgrading to an LED-compatible model.

What halogen wattage do they replace?

The 345 lumens output is equivalent to a traditional 50W halogen GU10. The 3.6W LED consumption represents over 90% energy saving compared to the halogen it replaces.

What's the beam angle and where does it suit?

The 36° beam angle provides focused directional light, making these bulbs suitable for recessed downlights, track lighting and accent spotlights. For wider ambient spread, consider GU10 bulbs with beam angles of 60° or above.

How long do they last?

Energizer rates these bulbs for a 15-year lifespan based on 3 hours of daily use, equivalent to approximately 15,000 hours before the LED output degrades below 70% of initial brightness.
