An Original Vintage Carbon Arc Light Reflector & 2 Carbon Arc Rods (see below for specifics) (Learn More) Carbon Arc Reflector and National Projector and Marble Double Eagle Carbon Arc Rods. Description from our consignor: "Before the development of high intensity lamps, motion picture projectors used carbon arc lighting. An electric current would be sent through a positive and negative rod. The rods are brought together which causes them to ignite. They are slowly separated until a steady (and extremely bright!) arc is formed. This light would be reflected off of a mirror like reflector through the film, lens, and onto the movie screen. As the carbon rods continued to burn, the gap would become farther apart causing the light to diminish. The projectionist constantly had to monitor the gap to keep the light from going out! Some projectors did this automatically. The tips of the carbon rods reach a temperature around 6500 degrees Fahrenheit!" If anyone knows more about this item, please e-mail us and we will post it here. Important Added Info: Note that this item contains two carbon arc rods (for the positive and negative sides), a carbon arc reflector, and an image of the system set up and another image with a diagram of the system in relation to the film and projection screen. Condition: good to very good. The carbon arc reflector is theater-used and is well worn due to the intense heat it was subjected to and there is a 2 1/2" crack near one of the edges. The carbon arc rods appear to have never been used and they are in very nice condition. Learn More about condition grades
