It's about 14 inches away. It does look more resinous now for sure. I'll leave it under this light for a few more days, if it gets too bad, I'll switch back to the cobs.
Even in an open room with no reflective walls i needed to keep it at 18”.
I think my sun system reflector hits max advertized par at 16”. Sunlight basically.
And i mean in the flower room. 18” over flowers.
