Robert Lights ✌ Posted October 21, 2017 Report Share Posted October 21, 2017 Cool white is the non-technical way to say 4100K. The Kelvin rating is the color that an object turns when heated to that temperature. (Kelvin is degrees centigrade starting at absolute zero) Warm white corresponds to 3000K. Light white is 3500K. Daylight ranges from 5000K to 6500K. Quote Link to comment Share on other sites More sharing options...
