These would be just like the Radion when assembled and for a few hundred less. Only these will have 42 LEDs and the Radion only has 32. As for more juice...most run their LED's at a fraction of capacity, so I am not sure why people want more juice. Even our buddy Mr Saltwater only runs his Radions at around < 60% at 18\" above water level or something like that from his measuring PAR video.
As I read more about them while posting this, the fixtures are actually quite similar in watts used for the LED's, 5 watt whites and the rest all 3watts and they are pretty much all the same model of Cree LED. Personally I like the spectrum more from Rapid. Dammit, and I was all ready for some Onyx from them in a few months, now I am looking at these instead.
