The PC's are 2x96w 10,000k and 2x96 true actinic. Both bulb types are CSL. For the first month or so the actinics are rather violet looking depending on day to day burn time but settle in to a very nice blue after that and the coral fluoresence has never been better.wseaton said:How are you mixing your PC lights BTW? 50/50 plus actinic? What brand are the actinics? I'm wondering since I'm trying different brands of the actinics and can't get quite happy, and I really like the looks of your lights.
