Condition of the official brightness tests




by bigdai » 13/02/09, 08:53

Hello,

I've been researching the official light test conditions for some time. I saw at this address (https://www.econologie.com/forums/comparatif ... t4009.html) tests on the measurement of luminosity. I would like to know if those are the official conditions or not.

Thank you in advance for your help.
