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
