Halogen Light Bulbs

Best uses for halogen bulbs

Most people think of halogen light bulbs as being different from the run-of-the-mill incandescent bulb, but in reality they are really based on the same technology. Halogens have a tungsten filament like the old incandescent stand-by, but they also have a glass enclosure filled with halogen gas. The gas helps amplify the light output of the bulb, making them brighter than regular bulbs, and also helps carry evaporated tungsten particles back to the filament. This process helps extend the lifespan of the halogen bulb. They are best used in high output task or desk lamps, where bright light is needed for reading, artwork, or other activities. When installing a halogen bulb, remember not to touch them with your bare fingers. Doing so can leave oil deposits on the glass, which can shorten the lifespan of the bulb. Use a rag or a piece of plastic to handle the bulb when installing. Learn more about the different types of bulbs in our Light Bulb Identifier and Finder Guide.
