radions are overglorified AI's plain and simple. The whole 4 AI's on a 120 is absurd, I've seen plenty of tanks w/ 2 and grow sps fine with that.
Radions have red and green lights yes, only time you see the red and green light is if you adjust it to those color and how often is that.
You barely ever use them. Then extra features? Extra features being using the computer that you use basixcally once to set them adn forget it or adjust them every few months...
Or the it interacts with the mpW, all it does is put them in night mode currently (great feature). OH MY BUT THE NATURAL MODE, the whole idea of natural mode is a new feature and just to add a bell and whistle. People have been growing corals under PC, MH, and T5 all in an unnatural light successfully for years.
Yes the Ecotech Radion concept is nice, but it is too new of a generation of light and for the cost NOT worth it at THIS POINT. In a year or two with new generations of lights absoluitely I think they'll be set.
But at this point save your money and get the AIs. They'll both grow your corals and both have good colors, but instead of spending $1700 (oh yeah $750 + $50 hanging kit (without the screws) You'll spend $1,000 and have plenty of coverage with a hanging kit (WITH SCREWS OMG!!!).
And I'm sure some people will say but but but my radion it it is so nice.
It is a nice light and good concept, not for the price or execution though.
i've personally owned MH, T5, and the radion. I'm thinking of going back to the T5 or even the AI Sol Blues and not afraid to admit it.
Lot of these radion folks don't want to/can't accept the fact they paid almost double for a light that does the same thing. BUT BUT THE FEATURES, NOPE
