Help identifying these lamps

[Audrey Dunlow]

I just scored all of this for $15, but I don’t know much about them. Can anyone give me some info on them (when they were made, what they’re worth, etc.)? Thanks in advance!

The two tubular ones look like Hot Rock Lamps by Lite F/X. The cone shape one is a Wizard by Lava Lite

Do you know how old they would be?

Hard to tell wizards, the varied in production standards over time

most are late 90s

Yep, 90s Lava brand Wizard and the "Hot Rock Lite." They couldn't sell a LAVA lamp since "Lava" was trademarked, so they cheekily skirted it by referred to "hot rock" and "liquid earth." The lava versions had boring flow, but the glitter Hot Rocks were nice and sparkly.
