I would like to share some PAR readings for two lights.
They are mounted 7” above water line.
I was surprised at the intensity of the lights at 100% blue, 800-900 at the surface, 140-170, 24” down.

Visparspectra 165watt.
20% blue, 1% white
Surface 400-425
12” 175-250
24” 75-120

Nicrew Hypereef 150
30% blue, lowest white setting.
Surface 365-400
12” 146-170
24” 65-110

I would say you already know this, but the non-existent white is what is killing the PAR especially lower. That's quite a bit of PAR drop at 12 inches. Would be perfect for an LPS, Softie tank for sure.
