Gold Starlite Century(left) next to a Silver Aristocrat. Both lamps underwent goo-kit revision. Century has red liquid with a combo lava including florescent green & green coloring. Lava is translucent and creates a prism effect changing color as the light angle changes--it's a real trip! In the Aristocrat I used blue liquid with yellow lava. Both lamps are running on dimmers which regulate the flow rate and size of the lava balls. Max heat creates faster, smaller lava balls.
