Whats up guys N Gals. I was wondering a few things about Radion lights from those who use them. First would be natural growth patterns of SPS, are you seeing this ?? Are you using just the radions OR supplementing with T5 ?? Finally is there anyone who has run these lights for more than one or two years and would have measured Par output when new VS after some long run time. Are the lights Loosing Par after a year or two of use and needing new LED pucks installed. I know that not many would measure this so it may be a long shot question.
