CRI can be defined as ‘the unit of measure of the light colour quality’. Devised by the International Commission on Illumination (CIE), it is the measure of a light source’s ability to show object colours ‘realistically’ or ‘naturally’.

Advances in the CRI ratings of LEDIt can range from 0 (for example, a low pressure sodium vapour lamp, which is monochromatic meaning only one colour light is emitted), to 100 which means that the light source makes objects appear the same as they would under natural sunlight.

Traditional incandescent lamps were CRI >100 since all colours in their colour spectrum were rendered equally. If lighting with a low CRI rating is used, the consumer may find that the colours of certain items appear slightly different than they would in natural sunlight, for example, you may find it difficult to distinguish between a navy and black shirt in your cupboard. The CRI rating of a light fitting or lamp is a very important, but frequently overlooked, factor to take into consideration.

With the inception of LED lighting it has been a difficult metric to match with that of incandescent lamps and, in a lot of instances, LED has not been seen as a worthy replacement or substitute for incandescent lamps and, for that reason, has been ignored for a long time. In 2016, the highest CRI rating for an LED was only CRI <80 but recent advances in LED technology have seen an increase in the CRI rating of LED fittings to more than CRI >80, and in some cases, even CRI >90. Spazio Lighting is always on top of the latest technological advances and is now supplying a variety of LED fittings with a CRI rating of 90 and higher.
