K Series GU10 6W 50W-eq 100° 500lm LED Spotlight Bulb - Daylight

This K Series GU10 spotlight is a directional LED bulb that drops straight into a standard mains GU10 twist-lock holder, no transformer needed. It draws just 6W while putting out 560 lumens, giving the punch of an old 50W halogen at a fraction of the running cost. The 6500K daylight tone is crisp and bright, and a wide 100 degree beam spreads the light evenly rather than throwing one tight spot, so it suits both fill and feature roles. In the US this is the same GU10 mains spot you would reach for in place of an MR16, but without the low-voltage driver the GU5.3 fitting demands.

The 100 degree beam and 560-lumen output make this a good fit for ceiling spots and adjustable downlight bars in kitchens, hallways and living rooms, where the wide spread keeps worktops and walkways well lit without harsh pooling. Group several across a ceiling for general coverage, or aim one to graze a shelf, alcove or picture for a bit of accent. The daylight colour reads well in task areas and rooms where you want a clean, neutral light rather than a warm glow. Coverage depends on how many you run and how high they sit, so plan spacing around the beam spread rather than a single bulb.

Built around a PAR16 lamp on a GU10 cap, the bulb measures just Ø50 by 56 mm and weighs 18g, so it sits flush in compact recessed and surface spot fittings. It runs on 220 to 240V AC mains, returns a CRI of Ra 80 for honest everyday colour, and is rated for 20,000 hours of use. This bulb is non-dimmable, so pair it with a standard on/off switch rather than a dimmer circuit. The white casing keeps it discreet once installed. The K Series spans a range of caps and tones if you need to match other fittings around the home.

Product Specification Sheet

Range Datasheet

Which fitting does this bulb need?

It has a GU10 cap, the standard twist-lock mains spotlight fitting. You simply push it in and turn a quarter to lock it, with no separate transformer required. It is not an MR16 or GU5.3 low-voltage type, so do not fit it to a 12V driver circuit.

What old bulb wattage does it replace?

It draws only 6W itself but gives the light of a 50W halogen GU10, at 560 lumens. The 6W figure is the bulb's actual consumption, so you keep the brightness while cutting energy use sharply over a 50W lamp.

What does the 100 degree beam angle mean?

It is a wide beam for a spotlight, spreading light over a broad area rather than focusing one tight pool. That makes it well suited to general ceiling lighting and even fill across a room, while still working for gentle accenting of shelves or features.

Is this bulb dimmable?

No, this is a non-dimmable bulb, so it should be used on a standard on/off switch. Fitting it to a dimmer circuit may cause flicker or buzzing and is not recommended. If you need dimming, choose a bulb listed as dimmable instead.
