Perhaps he wants a measurement from 20" from the side of the light fixture to see if and/or how much the light degrades? I would say take a reading at the canopy top then move the meter 20" to the side and see what it reads? I'm only speculating of course but that would be a way to see how much coverage is ideal for the fixture.I'm not quite sure what you are asking me to do here?
