This question is primarily targeted towards those who have Integrating sphere setups.



How would you compare the relative light output percentage (between 2 lights) from measurements taken from an integrating sphere when compared to measurements taken by doing a ceiling bounce lux reading?



For example light A measures 200 lumens in the sphere, and light B measures 500 lumens.



Light A measures 50 lux when doing a ceiling bounce and light B measures 125 lux.



Just wanting to know roughly how accurate a ceiling bounce is for comparing relative light output between 2 lights.
