Most LED bulbs sold in the UK sit at CRI 80. That is the minimum for general-purpose lighting, and in many situations it is sufficient. But in spaces where colour accuracy is a practical requirement, CRI 95 to 97+ changes what a room looks and feels like.
Dulora's Ultra-High CRI collection gathers the bulbs that reach CRI 95 to 97+: Edison filament, GLS, candle, fancy round, tubular, G95, G125, GU10, and MR16 forms across warm and extra warm colour temperatures. These are the bulbs specified by interior designers, photographers, and hospitality venues where colour rendering is non-negotiable.
For most UK homes, the difference is visible in how food looks under kitchen downlights, how artwork appears on a lit wall, how skin tones render in a bathroom mirror, and how textiles and paint colours appear in the living room.

High CRI LED Bulbs: When Colour Accuracy Is Not Optional
What does CRI measure and why does 95+ matter?
CRI (Colour Rendering Index) measures how accurately a light source renders the true colours of objects compared to a reference source, on a scale of 0 to 100. At CRI 80, most colours appear reasonably accurate but warm tones, reds, and skin tones can appear flat. At CRI 95+, the rendering is close to natural daylight: reds are rich, skin tones are natural, and textiles appear as intended.
The difference is visible to anyone who sees the same object under CRI 80 and CRI 95+ side by side.
Where does high CRI make the biggest visible difference?
Kitchens, bathrooms, and any room where artwork or textiles are significant. In a kitchen, CRI 95+ makes food appear more vibrant. In a bathroom, skin tones appear natural under the vanity mirror. In a living room with artwork, colours appear as the artist intended.
For hospitality venues, the commercial difference is measurable: food and drinks look better under CRI 95+, and the overall impression of quality is higher.
Do I need high CRI in every fitting?
Not necessarily. The priority fittings are those where colour accuracy has a practical impact: kitchen downlights, bathroom vanity lights, art-lit wall fittings, and exposed-bulb pendants. In hallways, utility rooms, and outdoor fittings, CRI 90 is typically sufficient.
A practical approach: CRI 95+ in kitchens, bathrooms, and living rooms; CRI 90+ elsewhere.
