A halogen lamp is an incandescent lamp that houses a tungsten filament contained with an inert gas and a small amount of a halogen such as iodine or bromine. Halogen and Zenon technologies allow you to get more light from fewer watts, but they are still rather energy-inefficient. Although a 100-watt Halogen provides about 250 watts of incandescent equivalent light, the bulb still requires 100 Watts -- whereas a fluorescent would only need to be about 60 -75 Watts (although such a high wattage CFL is not made.) The benefit to Halogens and Zenons are that they are small in size compared to incandescents or fluorescents. Zenon bulbs are also significantly more efficient than halogens, as they operate at a lower temperature and maintain a better quality of light. Halogen Energy Savers (from Philips) are uniquely designed to provide the same crisp, white halogen light as standard halogen bulbs, but they use much less energy. When using Halogen or Zenon bulbs, the best option is usually to choose low-voltage systems that operate at 12 volts as opposed to the standard 120 volts seen in regular incandescent light bulbs.
When it comes to energy efficiency, the easiest way to start cutting down your monthly bill is through your home’s lighting. By making simple changes to the types of bulbs you’re using, you can be more eco-friendly while saving yourself a pretty penny. Due to all the changes the green lighting industry has undergone in just the last few years, it’s easy to be overwhelmed with all the options that are available. But fear not – if you’re looking for some insight into the wealth of green lighting alternatives available today, this handy guide will give you the basic foundation you need to upgrade your bulbs and reap the financial and environmental benefits of energy-efficient lighting!
