I have two 4’x4’ tents and one has a Timber 48SAM which is 4 QB 288s at 480w. I have that one a light rail mover that moves the light back and forth every minute or so pausing for 15 seconds at each end. So they don’t get the full light all the time. Some of these plants are within 6”. The other tent I have 3 QB 288s at 320w and 4 QB 132s at 200w. Some of these are within 10”.
I’ll raise the lights tomorrow and see how they react. I have a par meter but I haven’t really pulled it out since I added plants. I’ve been meaning too, glad I read this. I’m at 30w and 32.5w per sqft so it’s probably not so bad.

better rethink
I have to keep my canopy at least 20 inches from the panels, 24 is better. They don't get burnt - they just get too much light. 
The 304s are pretty intense. I also have 120s for veg, with the same board size, and I can get within a foot of those.
It's just a buncha numbers added up. The COBs probably have a limit of 300 watts each before they burn up. 
just kidding. This shows me I have a lot more to learn about lights.
She has the same buds her mother had - purple inner buds and purple veins in the sugar leaves.
