What kind of Icon Lamp did I get from Free Cycle?

[Manix5]

I check Free Cycle from time to time and this week someone offered a lamp across town. I debated going to pick it up, but I'm glad I did. I expected an ordinary lava lamp, but I got this Icon Ceramic lamp instead. What is it called? Considering all it cost me was about $5.00 in gas I'm pretty happy. The globe is clear/yellow and has a Lava Lite bottle cap. The numbers are smeared so I can't read them. The base also has a built in dimmer.

The top cap has been broken and glued, but it is not noticeable if put towards the back. See photo below.

I am thrilled with my luck. Any info about the lamp would be appreciated. Anyone have a ball park value?
