Household lighting accounts for about 8% of our energy costs in Queensland homes. You can reduce your lighting energy costs by more than 80% just by choosing more efficient lighting options.
Installing sensors or timers will ensure lights are only on when you are using a particular area. Taking advantage of natural light and reducing your need for artificial lighting will save you energy and money.
- Choose energy efficient lighting.
- Install sensors or timers to ensure lights are only on when you are using the area.
- Turn lights off in areas of the home not being used.
- Take advantage of natural light to reduce your need for artificial light and save energy and money.
- Install a sky tube or solar tube. It's a cheap and effective alternative to a skylight and can brighten your home.
- Choose a light bulb colour between 2700-3300K for general areas and 3500-4100K for kitchen or work spaces.
Energy efficient lighting options
You can start saving energy and money instantly by replacing old light bulbs and fittings with newer, energy saving options such as Light Emitting Diodes (LEDS), Compact Fluorescent Lamps (CFLS), linear or circular fluorescents.
Light Emitting Diodes (LEDs)
- LED bulbs suited to standard fittings are increasing in variety. More options are expected to be available in the next couple of years.
- LEDs are more expensive to buy but have a life expectancy of up to 50,000 hours (that's 50 years for the average household light!) and can use up to 88% less energy than the standard incandescent.
Compact Fluorescent Lamps (CFLs)
- These use only about one fifth of the energy and last ten times longer than incandescent bulbs, due to the decreased wattage.
- They provide the same light level and are ideal for areas where lighting is needed for long periods of time.
- They produce less heat, which helps keep your home cooler in summer.
Linear and circular fluorescents
- These are also a good option to save power, with around the same efficiency as a CFL.
- Fluorescent lights use a small amount of power to start up. This phase lasts for only a few milliseconds, so it's best to turn off the light if you are leaving the room for a while.
