My light was at 40-50 cm from the canopy, higher tops being around 30. I placed a few bricks under my airpot and now the distance is 30-40cm. Is this too much light or not?
Well yeah I use both switches but 18" and higher seems like a pretty big waste to me. I know they're fine at 15" but I'm curious if 12" could cause stress

Those par stats are always higher than what the light actually produces but according it, you should probably keep it at least 18 inches from the canopy. Assuming the actual par is 75% of those stats, 14-16 inches would be minimum distance from the canopy.
