GU10 S Series 4.7W 39W-eq Dimmable Smart LED Spotlight - 110° 325lm Warm White

This S Series GU10 spotlight is a directional LED bulb that twists straight into a standard GU10 holder and runs on mains voltage, so no transformer is needed (unlike a low-voltage GU5.3 / MR16 cap). It draws just 4.7 W in place of an old 39 W spotlight, putting out 325 lumens through a wide 110 degree beam at a 2700K warm white tone. American shoppers searching for a GU10 LED bulb will find the same twist-lock format here, with a PAR16 spot profile measuring 50 mm across.

The 110 degree beam spreads light more broadly than a tight spot, which makes it a good fit for general accent and task lighting across kitchens, living rooms and hallways where several heads share the load. It works in recessed ceiling holders, surface spots and track heads alike. Because this is a directional bulb rather than an ambient ceiling fitting, think of it in terms of throw and pool rather than floor area: the warm 2700K output gives a soft, even wash that suits cosy living spaces and dining areas, with the wide angle reducing harsh shadows under each fitting.

Built to a compact PAR16 spot form at Ø50 by 54 mm and weighing 30 g, the bulb pairs an 85 lm/W efficiency with a Ra 80 colour rendering for natural-looking colour. It is a smart bulb with app and voice control, and it is dimmable, so brightness can be set to suit the room. The bulb is rated IP20 for dry indoor use, with a 15,000 hour rated life. We stock the S Series in matching cap and shape options so you can fit out a whole room from one range.

Product Specification Sheet

Range Datasheet

Which fitting does this bulb need?

It has a GU10 cap, the standard twist-lock mains spotlight fitting. Push it into the holder and twist a quarter turn to lock. It runs directly on 220 to 240 V mains, so no transformer or driver is required, unlike low-voltage GU5.3 or MR16 spots.

What old bulb wattage does it replace?

The LED itself draws only 4.7 W while giving 325 lumens of light, which is equivalent to a 39 W halogen spotlight. You get a comparable bright output for a fraction of the running cost, with a rated life of 15,000 hours.

Is this bulb dimmable and can it be controlled remotely?

Yes, it is dimmable and can be set to any brightness on a compatible smart system. It is a smart bulb, so it supports app and voice control alongside standard switching, letting you adjust the warm 2700K light without a manual dimmer.

What does the 110 degree beam angle suit?

The wide 110 degree beam casts a broad, even pool of light rather than a narrow spot, which works well for general and task lighting in kitchens, living rooms and hallways. Several heads together give smooth coverage with fewer harsh shadows underneath each fitting.
