GU10 LED Bulb 3.1W 250lm Non-Dimmable - Warm White 3000K

This is a GU10 LED spotlight bulb that draws 3.1W and gives 250lm of warm white light at 3,000K. The twist-and-lock GU10 cap is the two-pin push-fit type used in most UK recessed downlights and spotlight bars, so it drops straight into an existing fitting with no wiring change. The retail pack rates it against a 35W conventional spotlight and prints a 10 year, 10,000 hour lamp life. Its beam spreads to 110 degrees, which is wide for a spot and closer to a soft wash than a tight pool of light.

Warm white at 3,000K sits just above the yellow of an old halogen, warm enough to feel comfortable in a living room or bedroom but a little cleaner and crisper across a kitchen worktop. At 250lm this is a spot rather than a main room light; these earn their keep in a run of four or five downlights, on a three or four head spotlight bar, or picking out shelving, a cooker hood or an alcove. The wide 110 degree spread helps a row of ceiling spots overlap into even coverage rather than leaving scalloped pools on the floor.

The specification states that it is not dimmable, so wire it to a plain switch rather than a dimmer circuit, and check the switch before ordering if you are replacing halogens that were on a dimmer. It runs on standard 220-240V mains and carries an IP20 rating, which means it is for dry indoor fittings only. The energy rating is G, with the label quoting 4kWh per 1,000 hours. Each listing is one bulb, with a minimum order of five and sold in multiples of five. It sits within our wider range of LED candle, golf and GLS bulbs in the common caps.

Will this fit my existing halogen spotlights?

If the old bulb has two stubby pins that push in and twist a quarter turn, yes, that is the GU10 cap and it runs on mains voltage. Bulbs with two thin pins are 12V MR16 and will not fit.

How bright is it next to the halogen it replaces?

The pack rates it against a 35W conventional spotlight, and the specification quotes 250lm. That suits accent and secondary lighting rather than lighting a large room from one fitting.

Can I put it on a dimmer switch?

No. The specification states it is not dimmable, so it should be wired to a plain on and off switch. If your old halogens ran from a dimmer, that circuit needs changing first.

What does a 110 degree beam angle give me?

A broad spread rather than a tight pool, so a row of ceiling spots overlaps into fairly even light across a worktop, a hallway or a landing instead of leaving gaps between them.

How many bulbs do I receive, and is there a minimum order?

Each unit is a single boxed bulb. The minimum order on this listing is five units, sold in multiples of five, so the smallest quantity you can buy is five bulbs.

How long is the bulb expected to last?

The pack prints a 10 year lamp life, equal to 10,000 hours, and more than 10,000 on and off switching cycles, which matters on a landing or hallway switched many times a day.
