LED VS Halogen

What is Halogen?

Similar to incandescent bulbs, halogen bulbs contain tungsten filaments. But the difference is that a few halogen gasses from a halogen bulb mixes with the tungsten vapor and deposits it back into the filament rather than inside the bulb housing. This technology extends the lifespan and enables it to operate at higher temperatures than incandescent bulbs, increasing light output. Therefore, halogen bulbs often use quartz housings instead of glass.


More Detail about Halogen:

  • Halogen bulbs have a lifespan of up to 2,000 hours, but are still not as efficient as LED bulbs.
  • Halogen bulbs come in many shapes but are commonly used as MR, BR, AR and PAR, spotlights or floodlights.
  • They generate large amounts of infrared (IR) and ultraviolet (UV) radiation that can damage fabrics and artwork.
  • These bulbs require extremely high operating temperatures to emit light, which can cause burns if touched; high temperatures also prevent these bulbs from working properly in cold environments.
  • Because they operate at higher temperatures, halogen bulbs have a higher color temperature and produce brighter light.
  • Halogen bulbs are extremely sensitive to skin oils, which can cause them to malfunction or burst, so you need to wear gloves when putting them in the lamp
  • Halogen bulbs have frangible quartz shells and frangible filaments.
  • Halogen bulbs are fragile -- especially when they're near devices like fans, the thin filaments vibrate, shortening their lifespan.


    What is an LED Light Bulb?

    LED lamps refer to lamps that use light-emitting diodes as light sources and are generally made of semiconductor LEDs. The lifespan and luminous efficiency of LED lamps can reach several times that of incandescent and halogen lamps. Moreover, in recent years, with the improvement of diode technology, high-power, high-luminance light-emitting diodes have become more and more popular.


    More Detail about LED:

  • LEDs produce almost no infrared or ultraviolet radiation so it can be used to illuminate fabrics and artwork.
  • Power consumption is reduced by 75% compared to halogen bulbs.
  • Shatterproof bulbs are shock resistant and have no fragile filaments.
  • LEDs have low power consumption, which means they have low maintenance costs.
  • LEDs do not contain mercury, harmful gasses or toxins.
  • Due to their low power consumption, LEDs are an excellent alternative lighting solution for solar powered systems.
