Quote from: Ugly1 on September 03, 2023, 09:27:11 AM I can’t find my Sylvania catalog right now, but I seem to recall that ULX880 lamps were restricted to operation only on 480 volt reactor ballasts. Could have changed in later catalogs? I think the catalogs specifically mentioned the 480V series choke ballast compatibility was probably due to 1000W H36 mercury vapor HX autotransformer ballasts being discontinued early on. Even then, they could still be safely operated on the 120V 60Hz 1000W H36 mercury vapor HX autotransformer ballasts that I found in the GE I-line ballast compatibility brochure.
