I think that lots of people are measuring temps directly in the light. I''m pretty sure that temps must be measured in the shade. I wish I could find something definitive on this.
I know that if you want to know the temperature outdoors you never take your reading in direct sunlight.
In my cab, with all the fans on, the temp after three hours directly under the light was like 95 degrees. However, when I measured the temp in the shade it was closesr to 75 degrees. I think that the 75 degree reading is closer to the true temp in the cab.
I think that measuring the temp in the direct light is measuring the radiant energy of the lamp.
