I took some lux readings from the Finnex Planted+ 24/7 CRV,
the highest factory setting was 3pm at 1450 lux divided buy 70 = 20.7 PAR at the bottom of a 55 gallon full of watter.
I think 70 is what you are supposed to divide lux buy.
Something that is probably effecting the lighting is,,,
I do have a large piece of driftwood in the tank, and the water is slightly stained from the tannins.
I will test again once the water clears up.
