Thanks so much. Sound like I have something unique then, or at least because it was a second hand lamp, someone combined two lamps. Maybe the original cap got damaged. Though I've seen the same lamp in Youtube videos, but no one ever said what it was exactly. As I've mentioned though, it's gotten to the point where I've considered retiring it, to simply a show piece. While all the new ones are on a 6 hour cycle and then turn off for at least 4 to 8 hours in between use to rest. This old one takes maybe about 3 hours and then really starts to have the wax separate until it becomes one big mess of blobs. Sometimes little ones will continue to move around but then it gets to the point where it just sits there and hardly moves until cooled down.
That's why I pulled it out of the main display in the living room, it just can't seem to handle the same runtime the new ones can anymore. Sure it works, and heats up, moves around , etc. However, it doesn't seem to keep consistency after it's been on a while as the other do. Since I'm just now learning more about these lamps, when should Consider one at end of life? Like I said, it was manufactured in 96, I got it over 20 years from a thrift store so I don't know it's history prior to that. I know for me, I've used it randomly e.g. I used it regularly for a few years, then it sat for years just as a visual attraction, but off. Now in the last year or so, I've started using it more, and have since noticed declining health.
Anyway thanks for helping me at least partially identify it
By the way, with today's tech, I was hoping to see more smart Lava Lamps available. As it is, I have my main display connected to an Amazon smart plug, and a 6 outlet power strip connected to said plug so, at least I can automate them to turn off and on, on a schedule, or use voice control to turn them off, or on. Just would be nice to see a model with the smarts built into the lamp. Have a good night, and thanks again.
