Induction Street Lighting Compared to Other Source Technology’s Review of HPS, Induction and LED Street Lights

Color • CCT – correlated color temperature; a measure of the color appearance of a white light source. CCT is measured on the Kelvin absolute temperature scale. White lighting products are most commonly available from 2700K (warm white) to 6000K (cool white).

• CRI – color rendering index; a measure of how a light source renders colors of objects, compared to a reference light source. CRI is given as a number from 0 to 100, with 100 being identical to the reference source. 2/ GE Title or job number / 2/28/2011
