Use lighting efficiently

Last updated: 6 September 2022

Choosing the right light bulbs, light fittings and then using your lighting correctly – by turning lights off when you're not using them and using natural light wherever possible – will make your home more comfortable, energy efficient and save you money on energy bills.

Choose the right lights

LEDs and CFLS are the most efficient forms of lighting

Light emitting diodes (LEDs) and compact fluorescent lamps (CFLs) will cost you far less to run than halogen and other incandescent lights. A new bulb can produce the same amount of brightness (measured in lumens) as a traditional bulb using far less electricity (Watts).

Visit the Victorian Energy Saver website for information about lighting programs that can help you be more energy efficient.

The cost of running a light is directly related to the wattage of the light globe or lamp

The higher the wattage, the higher the running cost. Reduce your power bills by switching to LEDs and CFLs throughout your home, replacing halogen lights. Use the Light Bulb Saver app to identify the best light bulbs to replace incandescent and halogen bulbs.

Choose the right light fittings

Using downlights rather than pendant or fluorescent fittings will mean you need to install more lights, resulting in higher energy use and running costs. Plan energy efficient lighting to save energy and money.

Turn lights off when they're not in use

The longer your lights are left on, the higher your running costs will be. Switch lights off when they're not in use, to keep your lighting energy costs down.

Use natural light wherever possible

The size and orientation of your windows will affect the amount of sunlight entering your home. West, east and north-facing windows tend to be exposed to sunlight, while south-facing windows receive almost no direct sunlight. If you are planning a renovation, consider orienting your living areas and windows to the north, and rooms where you spend less time to the south. This will take advantage of the sun, keeping these rooms warm, light and bright.

Benefits of energy efficient lighting

Although CFLs and LEDs can be more expensive to purchase initially, they will save you money because:

  • they use up to 80% less energy to produce the same amount of light
  • you won’t need to change them as often.
