GU10 LED Spotlight Bulb 4.8W 450lm Non-Dimmable - Daylight 6500K

This is a GU10 LED spotlight bulb drawing 4.8W and giving 450 lumens, which we rate as a 50W equivalent under the GB lighting equivalence table. The light is 6500K daylight, the coolest and crispest of the common white tones, with a blue-white cast and no yellow in it at all. The beam is 36 degrees, a narrow cone that lays down a defined pool of light rather than spilling it sideways. The body is a white reflector with a clear faceted lens across the face and the usual two-pin twist-lock GU10 cap beneath, and the bulb is rated IP20 with an E energy rating.

GU10 is the standard spot fitting in British kitchen ceilings, and this bulb suits recessed downlights, surface-mounted spot plates and track heads that take the same cap. Daylight at 6500K is the tone to choose where you want colour to read accurately and the room to feel alert rather than restful: a kitchen worktop, a utility room, a garage or workshop bench, a home office, a garden room, or display and task lighting in a shop. In a living room or bedroom most people find a warmer white easier to sit under in the evening, so it is worth deciding room by room.

There is no dimming here. The pack marks the bulb non dimmable, so it belongs on a plain switched circuit; wired to a dimmer it can flicker, buzz or fail early. The pack prints a 15,000 hour lifespan and a 15 year lifespan. Each box holds one bulb and the minimum order is 12, sold in multiples of 12, which covers a ceiling of spots with spares put by. It sits alongside our wider range of GU10 LED bulbs, including a 3.6W version in warm white 3000K.

Which fittings will this bulb go into?

Any fitting with a GU10 socket, including recessed downlights, surface spot plates and track heads. Push the two pins in and twist a quarter turn to lock.

Can I put it on a dimmer switch?

No. It is non dimmable, so it needs a plain on and off circuit. On a dimmer it may flicker, hum or fail well before its rated life.

What does 6500K daylight actually look like in a room?

A crisp blue-white with no warmth in it, the coolest of the common white tones. It reads colours accurately and suits close work, but it is cooler than most evening living room lighting.

How wide a spread does the 36 degree beam give?

The pack calls it a narrow cone. The light stays tight and directional, so spots want spacing a little closer together than a wide beam bulb would need for even cover.

Is it a straight swap for an old halogen GU10?

Yes, provided the old lamp is GU10 rather than the MR16 pin type. We rate this one as a 50W equivalent, so compare on lumens rather than on watts.

How many do I receive on the minimum order?

Twelve bulbs. Each box contains a single bulb, and the listing is sold in multiples of 12, so an order arrives as 12 individually boxed bulbs.
