I was wondering if anybody has experienced a problem with Sylvania Octron tubes ( FO32/841/ECO )installed in fixtures that run an Advance Centium ballast ( rapid start, RCN-2S32-SC) The lamps that originally came with the fixture are Phillips F32T8/TL841 Universal HI VISION. The local wholesaler says that the ECO lamps should work "no problem" The Octron ECO lamps glow orange like and give a weird light. I though this was just one fixture until a few other fixtures were tried, resulting in the same "awsome glow". Could it be that the low mercury content ECO tubes are not designed for your regular T8 ballast??? Any comments???
