i took two measurements for you, use whichever one you were wanting. 1-measurement from corner to corner with a tape measure curving with the light. 2-measure in a straight line from one corner to the other. 1=23.5" 2=18" the first one is much more accurate of a measurement, i had to estimate where the measurement was on the other one cause the light is curved of course
