Understanding CRI in Lighting: Why Colour Rendering Index Matters More Than You Think
by Newfeel Laser on May 26, 2025
When it comes to professional lightingâwhether for a concert, gallery, retail display, or photography studioâthe quality of light can dramatically impact how we perceive colours. This is where CRI, or Colour Rendering Index, becomes a critical factor in choosing the right lighting fixture.
Letâs explore what CRI really means, how it affects visual environments, and why high CRI lighting is essential across a wide range of industries. We'll also look at some real-world examples of CRI in action, and recommend high-performance fixtures built for precise colour reproduction.
What Is CRI (Colour Rendering Index)?
CRI is a scale from 0 to 100 that measures how accurately a light source reveals the true colours of objects compared to a natural reference light, such as daylight or incandescent bulbs.
- CRI 90â100: Excellent colour fidelity. Colours appear vibrant, natural, and accurate.
- CRI 80â89: Good quality. Suitable for general use in homes, offices, and retail stores.
- CRI below 80: Colours may appear dull or distorted. Common in industrial or utility lighting.
The higher the CRI, the more âtrue to lifeâ the colours under the light source will appear. This becomes critically important in environments where visual accuracy is not just preferredâitâs required.
Why CRI Is Crucial in Stage and Professional Lighting
In stage lighting, the audienceâs perception depends not only on performance but also on how colours are portrayed under the light. A costume designed in vibrant red should not appear dull orange under stage lights. Similarly, a performer's natural skin tone should be preserved, not washed out or grey.
Case Example: Theatre Production
In a theatre setting, lighting designers often choose fixtures with CRI ratings of â„90 to ensure performers' skin tones and costumes are accurately displayed under the spotlight. During a recent musical theatre tour across Europe, lighting technicians used the Newfeel High CRI Spotlight (CRI â„97) to ensure consistent skin tones across varied venues, with lighting that mimicked natural daylight regardless of venue constraints.
Applications of High CRI Lighting Across Industries
Live Events & Stage Performances
High CRI lighting enhances costumes, makeup, and set designâcreating a fully immersive atmosphere for the audience. Concerts and large-scale shows often rely on LED PARs and spotlights with high CRI to maintain visual clarity under high-intensity lighting effects.
Retail and Product Displays
In luxury retail stores, lighting must present products in their truest colours. For example, jewellery stores use high-CRI LED lights to make diamonds and gemstones sparkle with their natural brilliance. A CRI of 90+ helps eliminate colour distortion, improving customer satisfaction and influencing purchase decisions.
Photography and Film Studios
Photographers and cinematographers need lighting that maintains skin tone accuracy and colour consistency across shoots. Using high-CRI fixtures ensures colour grading is easier and more natural during post-production.
Real Use Case: A wedding photographer upgraded their studio with Newfeel RGBW PAR Lights (CRI â„90) to eliminate colour shifts in bride and groom portraits, especially under mixed lighting conditions.
Healthcare and Medical Environments
Surgeons and dentists rely on colour fidelity to assess skin, tissue, or gum colour accurately. Inaccurate colours can lead to diagnostic errors. Thatâs why surgical lights typically feature a CRI of 95 or higher.
Museums and Art Galleries
Artwork demands lighting that faithfully renders original tones. A misrepresented hue can affect the perceived value and authenticity of an artwork. Gallery lighting typically features CRI 95â100.
How to Choose the Right CRI for Your Application
Choosing the right CRI depends on how critical colour accuracy is for your environment.

Also consider the Correlated Colour Temperature (CCT). For example:
- Warm light (2700Kâ3000K): Suitable for hospitality, home, and restaurant environments.
- Neutral white (4000Kâ5000K): Ideal for retail and office.
- Cool white (5000Kâ6500K): Used in studios, medical, and industrial lighting.
