How many theatre owners, managers, or operators have had their screen light levels checked with a light analyzer of some kind?

If you have, did your screen meet SMPTE standards? What light level did you have in the middle? How about your sides or corners?

Standard SMPTE 196M specifies an aim of 16 footlamberts screen luminance. Theatres are allowed a range of 12 to 22 footlamberts, but no part of the screen should ever be below 10 footlamberts.

I have written several articles on the subject of proper screen luminance and how to measure it:
