We have some can lights in our house that have been out since we purchased it. I finally took the time to replace them (they are on a vaulted ceiling). I found some exposed wire as I was going along and brittle wire insulation. I used electrical tape to patch it up, but I started getting worried as I went on and kept finding more.
The can says to use 50w bulbs. I found the exact same bulb that they had originally used here here on amazon. This is a 50w equivalent that apparently uses 39w.
I thought it wasn't worth it and cut out the socket, then taped up the ends of the wires. I showed this image to some co-workers and they think that the halogen is most likely causing too much heat.
I thought about replacing the lights with LED variants and trying to pull out the wire through the can to get a section that hasn't been fried. I don't know how much slack there is.
Is this a valid solution? Do I need to call a professional?
