Nimbus

The Nimbus Pro requires a leading edge (TRIAC) dimmer switch to function properly. Standard rotary or trailing edge dimmers may cause flickering or buzzing. If you're installing a new dimmer, check it's labelled as leading edge or TRIAC-compatible and rated for LED loads of at least 6W.

At 575 lumens, this 6W LED bulb replaces a traditional 80W halogen GU10 while using 92% less energy. It's bright enough for task lighting in kitchens, workspaces, or spotlighting where you need focused illumination. The 36-degree beam angle concentrates the light rather than spreading it wide.

CRI (Colour Rendering Index) measures how accurately a light source shows true colours, with 100 being perfect natural daylight. At CRI97, the Nimbus Pro renders colours with exceptional accuracy—crucial for kitchens where you're judging food freshness, art studios, or anywhere precise colour matching matters. Standard LEDs typically sit around CRI80-85.

4000K sits between warm white (2700-3000K) and cool daylight (5000K+), offering a crisp, clean light without the blue harshness of clinical environments. It's ideal for task-focused areas like kitchens, bathrooms, and home offices, but may feel too stark for cosy living rooms or bedrooms where warmer tones (2700-3000K) are typically preferred.

Yes, the Nimbus Pro uses the standard GU10 twist-and-lock base that's universal across UK mains-voltage spotlight fittings. At 52mm tall, it fits nearly all recessed and surface GU10 holders. Simply twist your old bulb anticlockwise to remove, then push the new bulb in and twist clockwise until it locks.

The 5-year warranty covers manufacturing defects, premature failure, and component faults under normal domestic use. It doesn't cover damage from incorrect installation, use with incompatible dimmers, or accidental breakage. Keep your proof of purchase, as you'll need it to make a claim if the bulb fails within the warranty period.
