In use
Set the Cosmic Wave on a flat surface out of direct sunlight, in a room of 68 to 75°F, and switch it on. The wax flows after 2 to 3 hours. Switch the lamp off after 10 hours at most and give it 2 to 3 hours to cool before you move it.
Check before you buy
- Your spot has 4 inches of flat space and 14.5 inches of height, on a desk, a nightstand or a dorm shelf
- An outlet is within reach of the cord and its on/off switch
- Small children and pets cannot reach the lamp while it is on: the globe gets hot
Pick another one if
You want motion without a wait. A glitter lamp or a battery mini moves from the first minute.
From buyers
What buyers say about the Cosmic Wave
Visually Beautiful and Soothing
I missed getting one of these when they were all the rage in the 70's, always wanted one, and finally saw this and bought it ! Good quality, nicely designed and made (and just as I remember them from long ago!). Glad I finally found and got one. Very soothing and calming to watch the wax blobs rise and all. Got the pink/Orange one, going back for the blue.
Cosmic Wave or Deep Ocean: which 14.5 inch lamp?
Same 14.5 inch size, same 20 oz globe, same 25 W bulb: the look decides. The Cosmic Wave has purple wax in blue liquid, on a painted silver base, and the Deep Ocean has green wax in blue liquid, on a painted silver base.
