They are easily identified by the long and complicated windings of their internal filaments, and by the very warm-yellow glow of the light they produce (many of the bulbs emit light at a ...
In 1878, Edison began working on a system of electrical illumination, something he hoped could compete with gas and oil-based lighting.

Companies simply ran different lines for the different classes of loads their inventions required. For example, Charles Brush 's New York arc lamp systems required up to 10 kV for many lamps in a series circuit, Edison's incandescent lights used 110 V, streetcars built by Siemens or Sprague required large motors in the 500 volt range, [ 2 ...
