Deco fluorescent stick lamp

Deco fluorescent stick lamp

A neighbour of my parents gave them this funny deco lamp for me as he knows I collect such stuff ;-)

There is a quite old looking Lindner 18 watts "universal white" tube inside. I don't know how old this and what kind of ballast it uses. The tube looks like it runs underdriven and the top of it is connected with a tiny wire twisted around the tube.

I have something that looks similar that uses a 15 watt T8 tube and preheat/switchstart system. The ballast and starter are in the covered up section.

Preheat Fluorescents forever!
I love diesel engines, rural/farm life and vintage lighting!

Have you tried it?
The single thin wire suggest an instant start ballast - I would guess the capacitive multiplier ignition/rectifier run style, running the lamp DC.

No more selfballasted c***

Yes I've tried it and it starts instantly. Not the brightness a 18 watt T8 tube should have. It is also flickering slightly. The ballast might be crappy...

I've seen quite a lot lightweight ballasts made as the capacitor plus multiplier. To stabilize the arc they use a series resistor, in order to really stabilize the circuit, it have to drop about 10..15V.
And for DC operation art equivalent cathode load, the current could be about 1/2 of the rated current, what is frequently used - these sticks would be too bright and glary on full current...
