LIHULA CULTURE HOUSE
Lihula, Estonia

There is a small screen on the lamphouse, where the xenon arc is projected. It is used to focus the lamp. If you set the arc right on the black lines, the screen should be properly illuminated. But quality control in the factory has been poor and you get better results if you don't follow it.
