Par numbers and leds also dont go hand in hand .. kessils are one of the most notorious for this. lets say a kessil 360N with both channels set to 100 would show around 70 only at the sand bed of a 20 inch tank ( personal experience) but leaving them at 100 on both channels pretty much kills any chalice in long term where as from t5s some chalices gladly take over 200 par.
not sure what you are running your orpheks whites at normally but anything more than 50% on radions whites i assume would bleach any acro.
im not saying one light is better than another but the way to compare leds is not by how bright they look or what par numbers they show. i personally wouldnt use any other led than radions ( one per 24 x 24 inch section, sps or lps or softies tank) but to each their own
