Based on the PAR charts posted on this forum...
Finnex Ray II is 70 PAR (at 20")
My PC is unknown... it is a 48" 4x 65.
I am guessing it is somewhere in the 40-60 PAR range (at 20")
Seems like trading the bulb replacements as well as reducing my wattage from 260 to 39 is a great savings. The new fixture would pay for itself in less than 1 year!
I would love to switch as long as it will support my plants.
Am I totally off base here?
