Halogen incandescent bulbs, compact fluorescent lamps and light emitting diodes are three types of energy-saving light bulbs. All of these three types are more energy-efficient than traditional incandescent bulbs.Continue Reading
Halogen incandescent bulbs have greater efficiency due to the gas that surrounds the filament in the bulb. Most bulbs meet the federal minimum energy efficiency standard. Compact fluorescent lamps are even better, since they use only one-third of the energy of a halogen incandescent bulb; however, most CFLs contain mercury, so they need proper handling and disposal.
Light emitting diodes are the most energy efficient lighting devices. They use only 25 to 30 percent of the energy of a halogen incandescent bulb, and they last eight to 25 times longer.Learn more about Lighting
