01 / The feeling
The Warmth Worth Keeping
A candle-soft glow with a distinctly golden warmth — this 2700K bulb recreates the beloved quality of old halogen light, wrapping bedrooms, sitting rooms and intimate evening spaces in flattering, cosy comfort. The Nimbus Pro delivers that rare balance between atmospheric warmth and true colour rendering, making it ideal wherever you're showing off artwork, serving dinner, or simply want textiles and skin tones to look their natural best.
At just 6 watts, this dimmable GU10 replaces an 80W halogen whilst delivering 575 lumens through a focused 36-degree beam. The CRI97+ rating means colours appear nearly as accurate as in daylight — exceptional for LED technology. It dims smoothly on standard leading-edge dimmers with no warm-up delay, and with a 40,000-hour lifespan and five-year warranty, you're investing in quality that genuinely lasts. Clear glass body, professional performance.

Good to know
A few questions,
before it comes home.
Does this GU10 LED bulb work with dimmer switches?
Yes, the Nimbus Pro is fully dimmable and compatible with leading edge (TRIAC) dimmer switches, which are the most common type fitted in UK homes. It dims smoothly from full 575 lumens down to a warm glow without flickering. If you experience any compatibility issues, check that your dimmer is rated for LED loads rather than older halogen-only models.
What does CRI 97 mean and why does it matter?
CRI (Colour Rendering Index) measures how accurately a light source reveals true colours, rated out of 100. The Nimbus Pro's CRI of 97+ is exceptional — comparable to gallery lighting — meaning reds, greens, skin tones and fabric textures appear vibrant and natural rather than washed out. This is particularly valuable in living rooms, bedrooms, or anywhere you display artwork, textiles or want flattering light for people.
How bright is 575 lumens and what's the equivalent wattage?
At 575 lumens, this 6W LED bulb is roughly equivalent to a traditional 50W halogen GU10 in brightness. The 36-degree beam angle provides focused accent lighting rather than broad room illumination, making it well-suited for spotlights, downlights, picture lighting or reading lamps. For general room lighting, you'd typically use multiple bulbs in a track or recessed fitting.
Will this fit my existing GU10 downlight fittings?
Yes, this is a standard GU10 fitting with the familiar twist-and-lock bayonet base used across UK downlights and spotlights. At 52mm height and 40g weight, it fits comfortably in most recessed ceiling fittings. Simply twist out your old GU10 bulb and push this one in with a quarter-turn clockwise — no electrician or rewiring needed.
Can I use this GU10 bulb in a bathroom or outdoors?
No, the Nimbus Pro is rated for indoor use only and lacks an IP rating for moisture or weather protection. It's not suitable for bathroom zones, outdoor fittings, or anywhere exposed to steam or the elements. For bathrooms or outdoors, you'll need a purpose-built IP44+ rated bulb or enclosed fitting.
What warranty does this LED bulb come with?
The Nimbus Pro is covered by a 5-year manufacturer warranty against defects in materials and workmanship. This reflects the expected lifespan of quality LED technology and gives you long-term confidence in the product. The bulb is also CE marked and RoHS compliant, meeting UK safety and environmental standards.
