Yeah, i dont understand why it looked so terrible. It was really the first time i had seen the radion in person. I have seen plenty of radions in action on youtube and non of them had this effect. It was very disappointing. The colors were not mixing on the sand bed. I could see individual colors moving about on the sand bed, hence the disco ball effect. I did notice that the more surface water aggitation, the worse the effect their was. Also it was not that bad on the coral, it was horrible on the bottom of the tank and sand bed. On the small tank where the light was mounted like 4" from the waters surface, the disco effect was really pronounced and weird looking, kind of psychodelic looking. So if anyone has seen the shimmer of a kessil a350, well it was close to that shimmer but the colors were not blending, i could see the individual led colors bouncing around on the sand. Has anybody had this happen with the radions? I could not deal with that going on in my tank. Consequently the lfs had the older ai sols on display as well and they were even worse. When i pointed it out to the employees, they just said it was shimmer. I thought maybe i was seeing things until my wife and a few others commented on how bad the lights looked.
