The item being measured here is a lightbox, not a monitor, so turning off the room lights is appropriate if the monitor adaptor is not being used.

On your point of measuring monitors with or without the room lights on, I have always measured monitors (CRT and LCD) with the room lights off and never had any cast issues.

One important point, if there are any other light sources on in the room that cannot be turned off (such as equipment power indicators or other monitors, etc.), I cover the item being measured with a black, light blocking cloth.

Are you sure?

I have seen others, and  my own, profiled monitors with lights off and
can see a hard cyan cast.
