I have 20 year old track lights that I would like to replace. They are Lightolier brand which is now owned by Philips. The track heads have transformers in them that buzz loudly. New track heads are hard to come by and are about $100 each.
When they were installed, they were recessed to be flush with the ceiling. Can I replace the track without replacing the recessed fixture? I can't tell if the track and fixture are one piece, or if the track is a separated piece that fits inside the fixture.
The track part is 48 inches (4 feet) long and 1.25 inches wide. The recessed part is about 6 inches longer and wide enough that the track part appears to fit perfectly inside.
Here is one of the track heads that I took apart. It has a surprising amount of circuitry in it. I would have expected the wires to connect directly to the bulb without anything intervening.
