I use my ceiling 8' florecent lights at a constant distance to calibrate my meters for the past 30 years. Just be aware that color temps do make a difference, I use daylight lamps but still be aware there are variables so don't use it as a definative since age of the lamps makes a difference too. Use it as a check but compare as well. |
