Energizer LED GU10 Bulb, 3.1W, 230 Lumen, Warm White 3000K

Energizer products are recognised as one of the most trusted and highly desirable consumer lighting brands. This compact GU10 LED bulb (model S8821) gives 230 lumens of cosy 3000K warm white light from just 3.1W, roughly a 35W halogen-equivalent output. Measuring a compact 50 x 54mm, it's a low-cost, energy-efficient replacement for smaller halogen GU10 spotlights.

• Compact 50 x 54mm size to suit shallow or space-restricted fittings

What this bulb is best for

The softer 230 lumen output and warm 3000K glow suit smaller downlights, hallways, landings and cosy corners where a lower-intensity, halogen-like light is preferred over a brighter, high-output spotlight.

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

Is this Energizer GU10 bulb dimmable?
No, this S8821 model is non-dimmable. Fitting it to a dimmer switch can cause flickering, buzzing or premature failure, so keep it on a standard on/off circuit.

Is 230 lumens bright enough for a hallway or landing?
Yes, 230 lumens is a modest, comfortable output well suited to circulation spaces like hallways and landings, where you want gentle, functional light rather than a strong task spotlight.

What size fitting does this bulb need?
It measures approximately 50mm wide by 54mm long, a standard GU10 size that fits the great majority of GU10 downlights and spotlight fittings.

What's the difference between this and Energizer's 345 lumen warm white GU10?
Both are 3000K warm white and non-dimmable, but this 230 lumen bulb draws less power (3.1W) and gives a softer, lower output, while the 345 lumen version is brighter and better suited to larger rooms.
