LED Intensity

[Cal_stir]

I have a DIY LED , it's a 72 led unit, 36 XPG white, 36 XPE blue and royal blue, spread out on a 4' x 1' heatsink 3 inches above the water on my 90 gal 48x18x24, no optics, my white drivers are set at 1.3 amp and my blue drivers are set at 1 amp, I run my whites at 85% and my blues at 100% it looks about 50% brighter than my 4 bulb t5 ho, I am LPS Zoa dominate and all growing well.
I think part of the problem with the AI and Radion units is the concentration of the LEDs
