Home Lighting

Lighting accounts for about 10% of the average household’s energy budget and is perhaps the best place to get started when making the effort to save electricity and money.

Energy-Efficient Lighting

Ways to Save

Ways to Save

  • Light Bulbs: If you’re still using traditional incandescent bulbs you can save simply by buying a different type of bulb. Traditional incandescent bulbs waste a lot of energy to produce light. Newer, energy-efficient light bulbs use up to 80% less energy while still providing the same amount of illumination, and they last a lot longer.
  • Lighting Controls: These offer convenience and help you save money by controlling the amount of wattage or reducing the time lights are on but not being used.
  • Decorating: Use loose-weave window curtains and decorate with lighter colors that reflect daylight.
  • Turn Your Lights Off: Take advantage of natural daylight and turn your lights off when they’re not being used.
Common Types

Common Types

Energy-Saving Halogen Incandescent
Energy-saving, halogen incandescent bulbs have a capsule inside that holds gas around a filament to increase bulb efficiency. This type of incandescent bulb is about 25% more efficient and can last up to three times longer than traditional incandescent bulbs.

LEDs
LEDs (light emitting diodes) are small in size, but can be grouped together for higher intensity applications. They’re better at casting light in a single direction than other forms of lighting. LEDs use up to 80% less energy and last about 25 times longer than incandescent lighting. LEDs emit very little heat. In comparison, incandescent bulbs release 90% of their energy as heat and CFLs release about 80% of their energy as heat. Common uses for LED lighting include industrial and commercial lights, under-cabinet lights, recessed-down lights, holiday lights, and to light outdoor areas such as gardens and walkways.

Sensors

Sensors

  • Motion Sensors: Automatically turn outdoor lights on when they detect motion and then off shortly after. They are most useful for outdoor security and utility lighting. Since they are only needed when it’s dark outside these are often used in combination with a photo sensor.
  • Occupancy Sensors: Detect indoor activity within a certain range and automatically turn the lights on when occupants enter a room and off when the room is no longer occupied; providing convenience and energy savings.
  • Photo Sensors: Prevent lights from turning on during daylight hours. Typically used outdoors, but many LED nightlights have this feature. They offer convenience and energy savings.
