The Exo Terra Sun-Glo Halogen Neodymium Terrarium Lamp is a highly energy efficient broad-spectrum daylight bulb. Halogen emits higher amounts of UVA rays contributing to the physiological well-being of reptiles. The Exo Terra Sun-Glo Halogen Neodymium Terrarium Lamp also offers an increased level of infrared penetration for optimal thermo-regulation. Halogen bulbs are actually an advanced variation of incandescent bulb technology. One of the major factors that shorten an incandescent bulb s lifespan is the evaporation of the tungsten within the bulb. By adding a trace amount of a halogen gas inside the bulb a chemical reaction removes the tungsten from the wall of the glass and deposits it back onto the filament extending the life of the bulb. The higher temperatures of halogen lighting contribute to a whiter light a higher light output and a greater efficiency.
