GU10 ES-111 12W 92W-eq Dimmable LED Spotlight 850lm 40° IQ-LED - Cool White

This GU10 LED spotlight bulb is a directional ES-111 lamp that draws just 12 W while replacing an old 92 W bulb, so it cuts running costs without losing punch. It puts out 850 lumens through a 40 degree beam, giving a defined cone of light rather than a wide household spread, which is exactly what a spotlight is meant to do. American shoppers searching for a GU10 spot will recognise this as a directional reflector lamp on the standard twist-lock mains cap. The colour is 4000K cool white, a clean neutral tone that sits between warm and daylight, and the Ra97 rendering brings out colour detail very accurately under the beam.

The 40 degree beam suits accent and feature lighting where you want to pick out a particular point rather than fill a whole room. Think of grazing a textured wall, lighting artwork, a shelf display or a kitchen worktop run, or directing light into a recess or alcove. Because the throw is controlled rather than diffuse, a single lamp covers a focused pool of light, and several can be spaced along a track or a row of recessed fittings to build up a sequence of bright accents. The ES-111 format gives a larger lit face than a compact spot, so the beam reads as a generous, even patch rather than a hard pinspot.

The bulb fits the GU10 twist-lock cap and runs straight from 220 to 240 V mains, so no separate transformer or driver is needed, unlike a low-voltage MR16 type. It measures Ø111 by 78 mm and weighs 154 g, in a silver finish. It is fully dimmable on a compatible dimmer, and the rated life is 45,000 hours. As an IP20 lamp it is for dry indoor use only, and outdoor or bathroom suitability depends on the fitting it sits in, not the bulb itself.

Product Specification Sheet

Range Datasheet

Which fitting does this bulb need?

It has a GU10 twist-lock cap, the standard mains-voltage spotlight base used in UK track and recessed fittings. You simply push it in and give it a quarter turn to lock. It runs directly from 220 to 240 V mains, so there is no transformer or driver to add.

What old bulb wattage does it replace?

The LED itself draws only 12 W but gives the light output of a 92 W traditional spotlight, producing 850 lumens. That is a large saving on running costs for the same level of brightness. The rated lifespan is 45,000 hours.

Is this bulb dimmable?

Yes, it is fully dimmable when used with a compatible LED dimmer switch. For the smoothest performance, pair it with a dimmer rated for LED loads. Mixing it on the same circuit as non-dimmable lamps can affect the result.

What does the 40 degree beam angle mean in use?

The 40 degree beam gives a controlled, directional cone of light rather than a wide household spread, making it well suited to accent and feature lighting. It works for picking out artwork, a shelf, a worktop or a textured wall. The cool white 4000K tone with Ra97 rendering shows colours accurately within the beam.
