Energizer LED GU10 Bulb, Full Glass, 4W, 345 Lumen, Cool White 4000K

Energizer products are recognised as one of the most trusted and highly desirable consumer lighting brands. This full-glass GU10 LED bulb gives 345 lumens of clean 4000K cool white light from just 4W, a 50W halogen-equivalent output, through a 36° beam. The full glass body gives it the classic look and feel of a traditional halogen spotlight, while running far more efficiently.

What this bulb is best for

The full glass finish and bright cool white beam suit living rooms, kitchens and hallways where you want the classic look of a halogen downlight without the running cost. As it's IP20 rated, keep it in dry indoor fittings rather than bathrooms or outdoor spaces.

How to fit it

1. Turn off the power at the switch or consumer unit before you start.
2. Let the old bulb cool down fully if it's just been switched off.
3. Twist the old bulb anti-clockwise a quarter turn and pull it free of the GU10 fitting.
4. Push the new Energizer GU10 bulb into the fitting and twist it clockwise until it locks in place.
5. Restore the power and test the light. No transformer or separate driver is needed, the driver circuitry is built into the bulb.

Frequently asked questions

What does "full glass" mean for this bulb?
Unlike LED GU10s with a plastic lens front, this bulb has a glass body and lens all the way through, giving it the traditional look and feel of a halogen spotlight while running on far less power.

Can I fit this bulb in a bathroom?
It's rated IP20, suitable for dry indoor rooms only. For bathrooms, check the downlight fitting itself is rated for the relevant zone (typically IP44 or higher for zone 2) and only use a bulb and fitting combination rated for that location.

Is this Energizer GU10 bulb dimmable?
No, it's non-dimmable, so it should be fitted to a standard on/off circuit rather than a dimmer switch to avoid flickering or buzzing.

How does this compare to Energizer's standard 4.2W cool white GU10?
Both give a similar 345 lumen, 4000K cool white output on a 36° beam, the main difference is the full glass construction here, which gives a more traditional halogen-style appearance.
