Eveready LED GU10 Bulb, 5W (50W Equivalent), 370 Lumen, Cool White 4000K

This Eveready LED GU10 bulb replaces a 50W halogen spotlight while drawing only 5W, giving 370 lumens of clean 4000K cool white light through a wide beam. It's a straightforward, low-cost way to relamp a halogen GU10 downlight with an efficient LED that still fits and locks into the same fitting.

Key features

• 5W LED consumption for a 50W halogen-equivalent light output
• 370 lumens of crisp 4000K cool white light
• Wide beam spread for broad, even room lighting rather than a tight spot
• Non-dimmable, for use on standard on/off lighting circuits
• Standard GU10 twist-and-lock base, no rewiring or transformer needed
• Around 85% lower running cost than the halogen bulb it replaces

What this bulb is best for

The wide beam and cool white colour make this Eveready GU10 a good general-purpose choice for kitchens, hallways and living areas where you want even, functional light spread across a room rather than a narrow highlight on one spot.

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 Eveready 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

Does "50W" mean this bulb uses 50W of electricity?
No. The bulb itself draws only 5W of power, 50W is the output of the older halogen GU10 spotlight it's designed to replace, so you get a similar amount of light for a fraction of the running cost.

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

Will this bulb give a wide spread of light or a tight spotlight?
It has a wide beam, so it spreads light broadly across a room rather than focusing it tightly on one area, making it better suited to general lighting than accent spotlighting.

What's the difference between this and a warm white GU10?
This bulb is 4000K cool white, a brighter, whiter light similar to daylight. A warm white (3000K) GU10 gives a yellower, cosier glow more typical of traditional halogen lighting.
