I've got a couple of 4' fluoro tube fixtures in which only one bulb lights. I thought I might be able to combine them into one fully working fixture, and pulled them apart. Neither has the old electronic ballasts, but they are different. Can't find much on the net to explain to me the theory of how these newer styles work.
The first is extremely simple and I've drawn the schematic below. The transformer and cap on one end have considerably different values than those on the other, so I wonder if that is likely the problem? I also have no idea what's in the white 'box' (current limiter?) noted on the schematic and in the pic.
The other fixture is very similar to the first with regards to transformers and caps, but in addition has PCBs--which I presume limit current. Maybe they are taking the place of the white 'boxes' in the first fixtures? This fixture has a transformer that measures open, so I'd guess that's the problem here.
Thoughts? I think/hope I've drawn the schematics correctly!
Thanks.
