• Consider using high-intensity discharge (also called HID) or low-pressure sodium lights.
  • Exterior lighting is one of the best places to use CFLs because of their long life.
  • Use outdoor lights with a photocell unit or a motion sensor so they will turn on only at night or when someone is present. A combined photocell and motion sensor will increase your energy savings even more.
  • If you have torchiere fixtures with halogen lamps, consider replacing them with compact fluorescent torchieres. Compact fluorescent torchieres use 60% to 80% less energy, can produce more light (lumens), and do not get as hot as the halogen torchieres. Halogen torchieres are a fire risk because of the high temperature of the halogen bulb.
  • Take advantage of daylight by using light-colored, loose-weave curtains on your windows to allow daylight to penetrate the room while preserving privacy. Also, decorate with lighter colors that reflect daylight.
  • Use CFLs in all the portable table and floor lamps in your home. Consider carefully the size and fit of these systems when you select them.
  • Consider using 4-watt minifluorescent or electro-luminescent night lights. Both lights are much more efficient than their incandescent counterparts. The luminescent lights are cool to the touch.
  • Use 4-foot fluorescent fixtures with reflective backing and electronic ballasts for your workroom, garage, and laundry areas.
  • Use task lighting; instead of brightly lighting an entire room, focus the light where you need it. For example, use fluorescent under-cabinet lighting for kitchen sinks and countertops under cabinets.
  • Turn off the lights in any room you're not using, or consider installing timers,  or occupancy sensors to reduce the amount of time your lights are on.
  • Install task lighting – such as under-counter kitchen lights or bathroom mirror lights – to reduce the need for ambient lighting of large spaces.
  • Use dimmers, motion sensors, or occupancy sensors to automatically turn on or off lighting as needed and prevent energy waste.
  • Install fluorescent light fixtures for all ceiling- and wall-mounted fixtures that will be on for more than 2 hours each day.
  • Consider light wall colors to minimize the need for artificial lighting.
  • Use compact fluorescent light bulbs (CFLs) in place of comparable incandescent bulbs to save about 50 percent on your lighting costs. CFLs use only one-fourth the energy and last up to 10 times longer.
  • Turn your lights off when you leave a room. Standard, incandescent light bulbs should be turned off whenever they are not needed. Fluorescent lights should be turned off whenever you'll be away for 15 minutes or more.
  • Installing a skylight can provide your home with daylight and warmth. When properly selected and installed, an energy-efficient skylight can help minimize your heating, cooling, and lighting costs.
