An update for my GFI. Yesterday I switched everything over to a new power strip. The program on my AC Jr. kicked in and all the lights came on at the same time and _bam_ the GFI tripped. I normally have them staggered at 1 hour intervals to simulate a surise/midday/sunset kind of thing. When I turned on the first two ballasts and then turned on my third an hour later everything worked fine. Today, with the lights back on the normal schedule, everything is fine. So this makes sense that is wasn't my bulb in the socket, but was the electronic ballasts and the RFI circuitry.
E-A-G-L-E-S, any update on your troubleshooting?
