Use task lighting to target work and leisure activities. This lets you reduce your overall room lighting levels. |
 |
|
Use energy-efficient light bulbs (CFL's), especially in fixtures that operate more than two hours a day. They use up to 80 percent less electricity and last eight to ten times longer than conventional, incandescent bulbs. |
|
|
Select bulbs carefully. Look for the highest lumens at the lowest wattage. Wattage is the power needed to make a bulb work. Lumen indicates brightness. | |
|
Keep light fixtures clean to gain the most illumination. | |
|
Select light fittings with reflectors that direct light where you want it and do not absorb too much light—coloured glass can halve light output, creating a need for higher wattage lamps. | |
|
Install daylight and movement sensors so outdoor lights switch on when they’re needed but don’t waste electricity. | |
|
Modern dimmer controls reduce greenhouse gas emissions as they reduce light output. They also extend lamp life. Dimmer controls can now also be used with some energy saving light bulbs (CFLs), but check the label first. |
