A light colour is often described as three numbers such as 830. The 8 refers to CRI index (score out of 10) which basically means how good the quality of the light is in rendering colour to the human eye. The 30 refers to the actual light colour. Add on ‘00’ to get the Kelvin rating, in this case 3000K.
