Released in 1945 by General
Released in 1945 by General Electric to promote the adoption of fluorescent lamps, "The Magic of Fluorescence" presents a short historical background of man's conquest over darkness, from the first time prehistoric man brought the flaming fagot into his cave, through the development of the taper, the candle, the kerosene lamp, gas, the incandescent bulb and finally the development of the fluorescent tube. The film shows how fluorescent lights (first introduced in 1938) are manufactured. The film combines live action and animation to show how fluorescent lights are manufactured, tested and packed, and shows how the lamp works in showing the role of electrons in the lighting device. The film was directed by Raphael G. Wolff with Frank Hemingway as narrator, and distributed by General Electric.

A fluorescent linear light bulb (00:54). A fire (01:03). A caveman using a torch (01:14). An oil lamp (01:30). Candles (01:41). A chimney lamp (01:52). A gas lamp (02:13). A chandelier (02:19). An incandescent electric light devised by Thomas Edison in 1879 (02:30). A carbon lamp (02:47). A tungsten lamp (02:51). A gas filled lamp (02:54). Nela Park, headquarters of GE Lighting (03:08).

The process of manufacturing and quality ensuring fluorescent linear light bulbs is displayed (10:28). The size and color is imprinted with ink (10:31). A phosphor coating is applied inside the tube (10:47). The coating is heat dried and inspected using a reflectometer (11:08). The exhaust tube, glass flare, and lead wires are assembled (11:31). The tubes go through a sealing machine (11:42). Air is exhausted from the tubes (12:14). An illustration of the heat facilities in the air exhaustion machine (12:29). The tube used to exhaust the air is sealed (13:08). The electrons are hermetically isolated (13:20). The base is sealed to the tube’s end with special cement (13:26). The lead wires are cut and soldered to the pins (13:42). The assembled light bulbs are inspected and tested (13:58). The bulbs are stabilized (14:07). The bulbs are operated under extreme conditions (14:17). The bulbs are packed for shipment to an outside concern for final inspections (14:39). Views of tests performed on the bulbs (15:37).

Motion picture films don't last forever; many have already been lost or destroyed. For almost two decades, we've worked to collect, scan and preserve the world as it was captured on 35mm, 16mm and 8mm movies -- including home movies, industrial films, and other non-fiction. If you have endangered films you'd like to have scanned, or wish to donate celluloid to Periscope Film so that we can share them with the world, we'd love to hear from you.
