Oh, that is great! Here I installed all 34W T12 fixtures with magnetic ballasts in the utility spaces to avoid any X10 interference. There are at least a dozen fixtures in several storage rooms, the utility room, my workshop, and the garage. I doubt that most are on even 10 hours a year. The garage and workshop are probably on less than 100 hours a year. So now all of these fixtures will have to be replaced by new ones with noisemaking electronic ballasts? $$$!
