Halogen 12 V Bulbs

Sort by:
The halogen lamp is also known as a quartz halogen and tungsten halogen lamp. It is an advanced form of incandescent lamp.   The filament is composed of ductile tungsten and located in a gas filled bulb just like a standard tungsten bulb, however the gas           in a halogen bulb is at a higher pressure (7-8 ATM). The glass bulb is made of fused quartz, high-silica glass or aluminosilicate. This bulb is stronger than standard glass in order to contain the high pressure.           
 
Advantages:
          -
Halogen Lamps are small, lightweight
          -Low cost to produce
          -Does not use mercury like CFLs(fluorescent) or mercury vapor lights
          -Better color temperature than standard tungsten (2800-3400 Kelvin), it is closer to sunlight than the ordinary tungsten
          -Longer life than a conventional incandescent
          -Instant on to full brightness, no warm up time, and it is dimmable
 
Disadvantages:

          -Extremely hot (easily capable of causing severe burns if the lamp is touched).
          -The lamp is sensitive to oils left by the human skin, if you touch the bulb with your bare hands the oil left behind will heat up once  the bulb is activated, this oil may cause an imbalance and result in a rupture of the bulb.
          -Explosion, the bulb is capable of blowing and sending hot glass shards outward. A screen or layer of glass on the outside of the lamp can protect users.
          -Not as efficient as LED lamps Metal Halide and HPS lamps
