German Fat Lava lamp

I got this today from the bootsale and wondered if anyone can id it for me please.
A heavy floor/table lamp with no shade.
The mark on the bottom is just two numbers 9082/55
On the top is a paper label which says Herda MAX 1 x150 Wat... I take it that Herda is Electric or similar in German?
There is one bulb in the top but it will take another inside to light it up.
Thank You for looking

These used to be attributed to Soendgen , but they are not , there has also been a connection to Kera Keramik and that's a bit shaky as well , the company that made these made a very wide range and styles , some of it really nice stuff but attribution 100% can't be made yet .

There might be a connection to Herda lifestyle design

It would appear Herda worked in conjunction with the Keramik Company .

Looks like this company started in 1994

Thank you all for your help, I thought electric because it was next to the wattage on the label and also when I put Herda into a translation site it came up with Herdadaplatte - Electric ring cover!!!!!
