All light fittings are not created equal and one of the key elements that distinguishes one from the other is the CRI – Colour Rendition Index. This is a key performance indicator and should be one of the first figures you look for when comparing products.
What is CRI?
CRI (Colour Rendering Index) is an indication of how accurate a light source is at rendering colour when compared to daylight. The scale is measured over 14 colours between 0-100. The higher the CRI, the better the colour rendering ability.
Why is CRI important?
LEDs struggle to light red colours. As you can see from the example above, products with low CRI make red colours look insipid. A high CRI will render a truer colour of the object, art or fabric that you are lighting. This will add real value to your projects ensuring colours looks as they should at night rather than a pale imitation.
What is good CRI?
When selecting LED fittings a good CRI is between 80-90. However a superior CRI is 90+. Do see below one of our top performing products, the Polespring LED downlight which shows a CRI of 96.
