I just converted my set up to vertical this round to try it out and WOW is it bright in there, TOO BRIGHT! I am running 600s right now and don't see how anyone could possibly work in the room with the lights on. How do you do it? I definitely don't want to compromise my vision. I am going to re read the sticky above for some tips I guess, but with that intensity I don't see myself rocking vertical for more this one round.
