Description:
Two filaments are anchored at the bottom of the glass tube. They are connected at the top by wire semicircle, held in place by four wires radiating from top of glass tube. There are also four wires looped around semicircle, but not soldered -- presumably only for keeping filament in place. Glass tube is cylindrical on bottom segment, with inner tube; then flattens out in middle; then becomes smaller cylinder in top segment, finally flaring slightly at top. Filaments anchored into bottom and middle segments. Connections are screw and bottom of bulb, both of which are covered with solder. Box is orange and blue, with picture of sun, rising over earth, looking at the bulb.

FunctionThis bulb was designed to produce light similar to the sun's.
Solder at two connections may indicate that wires were connected to this bulb without using a screw-in connection. It is therefore possible that this bulb was used in experimental circuits.
