What this bulb is best for

4000K cool white sits between warm 2700-3000K and daylight 6500K, giving a bright but not clinical light that works well in kitchens, hallways, landings and utility rooms where GU10 downlights or spotlights are fitted.

How to fit it

1. Turn off the power at the light switch (or isolate at the consumer unit if working on the fitting).
2. Let any existing bulb cool fully before handling it.
3. Twist the old bulb anticlockwise a quarter turn and remove it from the GU10 fitting.
4. Line up the pins of this Energizer GU10 bulb and twist clockwise until it locks into place.
5. Restore the power and test the light. No transformer or separate driver is needed – GU10 LEDs run directly from UK mains voltage.

Frequently asked questions

Is 4000K warm or cool light?

4000K is classed as cool white, a neutral shade that is brighter and crisper than a warm 2700-3000K bulb but not as blue-toned as a 6500K daylight bulb.

How compact is this bulb?

At 50x54mm this Energizer GU10 is a standard compact size, so it will fit the same recessed downlights and spotlight fittings as most other GU10 LED bulbs.

Can this bulb be used with a dimmer switch?

No, this is a non-dimmable LED GU10 and should be wired to a standard on/off switch rather than a dimmer to avoid flickering or premature failure.

How does 230 lumens compare to other GU10 bulbs in this range?

230 lumens is on the lower-brightness end of our GU10 range, suited to smaller rooms or fittings with several bulbs; for a brighter single downlight, our 250 or 345 lumen bulbs give more light per socket.
