After about 25 years my pool light seemed to be getting dimmer and dimmer. I removed the fixture and set it on the deck. Opened it up and could not believe what I found. It is loaded with a tar-like substance (extremely tacky...get it on your hands and it is hard to get off) that covers the inside of the fixture. Like someone painted it on. Seems to be about a cupful of it, covering the whole of the inside. The light was dim because it was beginning to cover the light bulb. I saw a 2009 thread where someone in Kingwood Tx found a similar thing, but there was no solution in the thread.
I attached a photo. Does anyone know what this is, how it got in there, and what I should do next?
