1. Go through your house and make a list of which lights are on the most. The most-used lights are the best candidates for replacement with compact fluorescent light or with LED LIghting.
2. For situations where you need the highest quality light focused on a very specific area, consider tungsten halogen lights – either standard or low-voltage. Avoid using halogen lights in torchiere floor lamps – they can be a fire hazard.
3. Make use of natural daylighting whenever possible, especially in rooms that are used a lot during the daytime. In some situations you may need to rearrange your furniture to position your work-space by a window or under a skylight. In an upstairs room, you might want to consider putting in a skylight.
5. If you choose to continue using incandescent bulbs, use one high-wattage bulb in place of multiple low wattage bulbs wherever possible. A 100-watt light bulb produces as much light as two 60-watt bulbs.
6. If you tend to keep outdoor lights on all the time, buy and install a photo-sensor or motion-detector.
7. Utilize lighting controls and install timers, dimmers, and occupancy sensors in appropriate rooms.
8. If you need a lot of outside illumination (for a tennis court or swimming pool, for example), consider replacing incandescent lights with HID lights (either high-pressure sodium or metal halide).
9. Use task lighting, which is focusing light on the area that you need light and avoid lighting up the entire room.
10. Turn off lights when not in use.
11. Clean fixtures, lamps, and lenses annually to remove dust and dirt that is preventing proper illumination and minimizing lighting efficiency.
12. Dispose of all fluorescent light bulbs properly.
13. Always Look for the Energy Star label when purchasing new lighting products.
