Energy-Efficient Lighting Systems

Lighting in a typical home is extremely inefficient. Only a small amount of energy consumed actually becomes light, while most simply adds heat to the interior of your home. Then the air conditioner must work harder to remove that heat, which consumes even more energy. 

Energy used for lighting can be reduced by as much as 70 percent or more simply by replacing incandescent bulbs with compact fluorescent lamps (CFLs), or by upgrading your lighting system to ENERGY STAR qualified, pin-based fixtures.
  
Benefits of Energy-Efficient Lighting: High efficiency lighting such as CFLs or low voltage lighting options greatly reduce the total energy used for lighting. Savings can be 70 percent or more. New LED lighting options are also being developed that use even less energy for an equivalent quality and lighting output. High efficiency lights significantly reduce the heat added to living spaces, which saves even more energy by reducing air conditioning demands. Your home will be brighter, more comfortable, and stay cooler in summer.
