I have three radions over my tank, all are in the same group and on a custom program. At the end of the day when lights are ramping down one light is much brighter than the other two and even has different colors on. I called tech support yesterday and they told me to calibrate all my lights. I did this but it did not fix the problem, I sent them an email last night but got no response. Anyone had this issue or know how to fix it.
