An incandescent light bulb is an electric light with a wire filament heated until it glows. The filament is enclosed in a bulb to protect the filament from oxidation. Current is supplied to the filament by terminals or wires embedded in the glass. A bulb socket provides mechanical support and the electrical connection. Piece of cake!

Contrary to popular belief, Edison was not the only inventor to speculate on a bulb to emanate light. He was, however, the inventor of the best version of the lightbulb.

Incandescent bulbs are manufactured in a wide range of sizes, light output, and voltage ratings. volts. They require no external regulating equipment, have low...
