There's nothing beautiful about our flourescent battens. A grey metal top and a plain glass bottom, and 2 flourescent tubes.
There are some retro poles lights that look like the standard Dublin type, only a bit less ornate.
In 1924 the first electrical street lighting was installed. 44V/200W incandescent in series. In 1934 and 1935 first mercury vapor and sodium lights were tested.
In 1950 the first flourescents were installed. In 1956 the first regular Gas Discharge lights were installed. In 1962 the last gas light was extinguished.

Today Vienna has got the following lights:

105 incandescents
198.584 flourescents
1.371 sodium low-pressure
32.810 sodium high-pressure
7.140 mercury vapor

There's some type of lamp that gives off a bright white light, but while heating up the light is intensely green. Are these mercury vapor too? They give off a very intense light and were commonly used in school gyms about 10 years ago. Now they went back to flourescents, much nicer to the eyes.
