3.6W GU10 LED Bulb Non-Dimmable - Warm White 3000K 345lm

A GU10 LED spotlight rated at 3.6W, giving 345 lumens of warm white light at 3000K. The retail pack calls it a 50W replacement, and that is the number worth checking, because it is the halogen spotlight this lamp is built to step into, socket for socket, using the same twist and lock GU10 pins already sitting in your ceiling. The supplier gives the beam as 36 degrees, a narrow cone rather than a wide wash, so the light lands where the fitting points it instead of spilling across the ceiling. It is not dimmable.

That narrow cone is what makes a spotlight worth choosing over a general bulb. In a kitchen, a run of these over a worktop puts usable light on the chopping board rather than on the wall behind it; in a living room they pick out a picture, a shelf or a fireplace. Track fittings and recessed downlights both take GU10, so the same lamp covers several jobs around the house. At 3000K the light reads warm rather than crisp, closer to the colour of the halogen it replaces than to daylight, which suits rooms you sit in during the evening.

Because it is not dimmable, wire it to a standard on and off switch; putting a non-dimmable lamp on a dimmer circuit tends to cause flicker or buzz and shortens the lamp's life. The pack from Energizer states a 15 year lifespan, quoted on the side of the box as 15,000 hours, which works out at a little under three hours a day across fifteen years. Its energy label, issued for this lamp, shows class E and a consumption of 4kWh per 1000 hours. One lamp comes per box, and we sell them in multiples of twelve, which is a sensible way to buy when you are relighting a whole ceiling at once.

Will this fit the GU10 downlights I already have?

Yes, as long as your fittings take a GU10 lamp. The two pins push in and twist a quarter turn to lock, in the same way a halogen GU10 does, so nothing else needs changing.

Can I use it with a dimmer switch?

No. This lamp is listed as non-dimmable, so it belongs on a standard on and off switch. On a dimmer circuit you are likely to get flicker, buzzing, or a shorter life from the lamp.

How does 345 lumens compare with the halogen spotlight I am taking out?

The pack rates it as a 50W replacement, so you should get a comparable level of light from a lamp drawing 3.6W. The beam is a 36 degree cone, so it is a directed pool of light rather than a broad spread.

What does 3000K warm white actually look like?

Warm and very slightly yellow, close to the colour of an older halogen spotlight rather than the bluish white of a daylight lamp. It sits well with wood, brick and warm paint colours.

How many lamps do I get in a box?

One. The retail pack in the photograph reads one light, so each unit of this listing is a single lamp. The line is ordered in multiples of twelve units.

Is it suitable for an enclosed or recessed fitting?

The manufacturer does not state a restriction either way on the pack, so we cannot confirm it. If your fitting is fully enclosed, check the fitting maker's own guidance on lamp type before installing.
