GU10 LED Spotlight Bulb 4.9W 44W-eq 120° 550lm IQ-LED - Warm White

This GU10 LED spotlight bulb gives a directional spread of warm light from a compact PAR16 form. It draws just 4.9 W yet delivers 550 lumens, standing in for a 44 W old bulb while using a fraction of the power. The colour temperature is a 2700K warm white, an inviting tone for living and dining spaces, and the wide 120 degree beam angle spreads light more broadly than a tight downlight spot. Across the Atlantic this twist-lock GU10 fitting is the mains-voltage equivalent of a bi-pin reflector lamp, and unlike a low-voltage MR16 it needs no separate transformer to run.

The 120 degree beam makes this bulb a flexible choice for general and accent lighting rather than a narrow pool of light. It suits recessed downlights and surface spotlights in kitchens, living rooms, hallways and bedrooms, where the warm tone keeps the space relaxed. Several together in a ceiling will wash a room evenly, while a single fitting can pick out a worktop, shelf or reading corner. The Ra 90 colour rendering shows skin tones, food and furnishings faithfully, so it earns its place in spaces where how things look matters. With an IP20 rating it is for dry indoor use only, so keep it clear of bathrooms, porches and any damp or outdoor position.

Built on the standard GU10 twist-lock cap, the bulb fits straight into a mains 220 to 240 V AC fitting with no driver or transformer to specify. It measures Ø50 by 55 mm and weighs 44 g, matching the usual GU10 housing dimensions, and the silver body keeps a neat profile within the fitting. Efficiency runs to 112 lm/W with a rated lifespan of 25,000 hours, so replacement is rare once installed. This bulb is non-dimmable, so pair it with a standard on/off circuit. The wider GU10 range covers other wattages and beam options to match the rest of a scheme.

Product Specification Sheet

Range Datasheet

Which fitting does this bulb use?

It has a GU10 cap, the twist-lock mains-voltage fitting found in most recessed downlights and surface spotlights. You push it in and twist a quarter turn to lock. As a GU10 it runs straight from the mains and needs no transformer, unlike a low-voltage MR16 GU5.3 lamp.

What old bulb wattage does this replace?

The bulb draws 4.9 W of actual power but replaces a 44 W old halogen or incandescent spotlight, putting out 550 lumens. You get a similar level of light for a fraction of the energy. The LED itself only ever uses 4.9 W.

Is this bulb dimmable?

No, this is a non-dimmable bulb, so it should be wired to a standard on/off circuit rather than a dimmer switch. Using it on a dimmer can cause flicker or shorten its life. If you need dimming, choose a bulb rated for it.

What sort of light does the 120 degree beam give?

The 120 degree beam is wide for a spotlight, so it spreads light broadly rather than throwing a tight pool. That makes it good for general room lighting and soft accenting. Combined with the 2700K warm white tone and Ra 90 colour rendering, it gives an even, true-to-life light across a space.
