Title: Carbon arc lightning question
Post by: Andy.E on March 08, 2002, 01:42:00 pm: Hi out there,

I am sorry this is not about a BULB but about antique lighting. I have just got a very old looking cardboard box with

"CIELOR Charbons pour lampes a miroir"

carbon sticks, seems they were used for lighting by burning an arc between them. Manufacter is "Charbons Lorraine", Societe le charbon lorraine, 45 rue des Acacais, Paris VXII E

Sticks are about 8 inches long and 0,25 inches in diameter.

I will get webspace till tomorrow to upload a few pictures.
Just was interested if anyone could know how old these are and if theres a collectors worth?
pics will follow, thanks till then

It seems as those carbon electrodes would be used in 35mm movie projectors, because till early 70's most projector lanterns did make use of voltaic arc as light source.
After those days, all machines were being gradually changed to short arc Xenon lamps. By the way, all today's projectors are factory equipped with Xenon lamps too.

But 1/4" (6,3mm) seems as a bit thin for cinematographic projection purposes, because most movie projectors did make use of heavier carbon sticks for high-current arcs (as thick as twice such gauge and more for currents up to 70 Amp. or so).

Best regards,
