Has anyone seen a lava lamp do this?

[Cheylynn Marie Owen]

When I first got this lamp It had the coil embedded vertically in the lava. I plugged it in and t worked fine then started acting up. I got this lamp from Goodwill and I am trying to figure out why this lamp is doing this

it might be over heating try a frosted bulb or a dimmer.

Is it a normal sized 20 oz. lamp? What wattage bulb are you using?

[Gwen Williams]

what bulb are you using in it, it appears to be overheating

[Erin]

How long are you running it? What bulb? Oftentimes, these issues will resolve with running the lamp several times. 

[Cheylynn Marie Owen]

A clear 40w and I think at most I have ran 8 hrs, most of the time though its about 5 or 6hrs. It started working like normal last night but I don't know if that is a one time thing or not yet as I have not turned it on tonight

[Scott Campbell]

If its a 20 oz, a 40 watt is WAY too ho. Try a 25 watt instead

[Gwen Williams]

what size globe is it 20oz, 32oz.  If you are not sure, post a picture of it next to a pop can and someone can tell you. Or measure the height

Thats a wizard. 32oz. Use a clear 40 watt bulb. Bend the bulbs arm as high as you can and sit the globe on top. That may help.

[Dr. WHAT?!]

Yeah thats what I was thinking, it looks like its under heated not over.
