What this bulb is best for

The bright, clean daylight white light and focused 36° beam make this TCP GU10 well suited to kitchens, utility rooms, garages and workshops, anywhere task lighting and colour accuracy matter more than cosy ambience. As it's non-dimmable, keep it on a standard switched circuit rather than a dimmer.

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 TCP 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

Can this TCP bulb be used with a dimmer switch?
No. This is a non-dimmable LED, so it should only be fitted to a standard on/off circuit. Fitting a non-dimmable LED to a dimmer switch can cause flickering, buzzing or premature failure.

What does 6500K daylight white actually look like?
6500K is a bright, slightly blue-white light that closely mimics natural daylight, it's a popular choice for kitchens, workshops and task areas where clarity is important, as opposed to the yellower glow of warm white (3000K).

How many bulbs are in this pack?
This listing is for a pack of 5 TCP LED GU10 bulbs, enough to relamp several downlights or a single multi-spotlight fitting in one order.

Is this bulb suitable for outdoor or bathroom fittings?
That depends on the IP rating of the downlight or fitting it's going into, not the bulb itself. Only fit it into a downlight rated for the location, for example IP44 or higher for bathroom zone 2, or a fitting specifically rated for outdoor use.
