A Brief History of Halogen Light Bulbs

The halogen lamp, also known as a quartz-halogen and tungsten-halogen lamp, is an advanced form of incandescent lamp which contains a small amount of halogen gas (hence the name). The first lamp of its kind, which contained the halogen chlorine, was patented in 1882. Subsequently, this pioneering lamp was followed by the first model to use iodine, which was produced and patented by the company General Electric in 1959.

Elmer Fridrich and Emmet Wiley, former General Electric employees, developed the halogen lamp back in 1955. Before them, a lot of people tried to build halogen lamps but weren’t successful, mainly because none of them had figured out how to stop the lamp from blackening.

Fridrich was the first one to consider that only a small amount of iodine is the solution. He proposed that the iodine could be used to surround the tungsten filament to allow it to burn at much higher temperatures without blackening the bulb. Back then, halogen lamps were mainly used to “bake” paint onto metal due to their high heat output.

After introducing more relevant improvements to the design, Fridrich and Emmitt began to test their lamps on aircraft wingtip lighting. By the ‘80s, lighter, more efficient halogens rolled off the production lines. The rest, they say, is history.
