Rollei LV-Source (05)
The light is generated by the 100W lamp in this casing.
Strange enough (for a 230Vac country) the Lamptension is 110V. There is a big power-resistor just alongside the lamp. Probably used as a voltage-divider.
The tube protruding from the right holds a lightsensor. This sensor is connected to a meter and with this you could check the lightoutput of the lamp.
