If its any consolation I've had a radion issue this week as well. Turns out one of the power supplies just up and died on me. Didn't take long to diagnose this problem but its still frustrating as all hell. For the price of these lights I'm a bit disappointed. The p/s worked great for the few months I've had it, no warning at all that something was wrong and when I came home for lunch one day the radion was blinking on and off.
Thankfully Dave from Concept came to the rescue for me and is shipping me a replacement/loaner. I'm just glad that it was only one of the lights and not all three at the same time. Your situation sounds far more frustrating, sorry
