thank you, but when windows arent light sources, but there is some light falling on them, can I simply add it up?

Thank you all so much, for help. Actually it has no physical significance, but if I can add it up normally, than it´´ s over the limit set by the law, which that is the meaning.

And when I have 1,5lx on one window and 0,5lx on another, smaller window, does it add up?

thank You for Your reply, I wasn´´ t sure, because one man told me that i can´ t add it up

Hello, I just found on google, that 1,5lx + 0,5lx=2lx. I wanted to check if it´ s true, but i couldn´´ t find anything on the internet. So was Google right or not?
