Hi Adrian, The lamp in the Kodascope 50 is specified on the nameplate as a 115 volt 400 watt lamp. It's a very big lamp with an elaborate filament stack- a real work of art in itself. Curiously the filament array is not parallel to the plane of the gate but rotated at an angle of about 45 degrees. Maybe they did that to get more light concentration focussed into the gate aperture, or maybe its the wrong lamp type, which is a real possibility after 75 years! There is a heat blocking shutter in front of the lamp that swings into place to protect the film if the projector stops running. The speed of the projector is adjusted by a rheostat knob on the lamphouse. The projector has two sprockets and a single claw pin. I ran a 200 ft roll of film through it , and it projects a very steady picture up to about 30 ins wide. Anyway running this projector really makes you appreciate the efficiency of modern halogen lighting and wide aperture lenses. Even though the little Kodascope is burning up 400 watts of lamp power, it's light output does'nt even come close to a modern projector with a 12 volt 100 watt halogen lamp. Even more though, you really appreciate a projector design that runs as good today as it did in 1932! Show me any video hardware that will last that long!
