Over half of all Victorian homes have inefficient lighting installed. Lighting costs make up around 11% of the average Victorian household’s energy bill each year.
What is energy efficient lighting?
Light emitting diodes (LEDs) and compact fluorescent lamps (CFLs) are the most energy efficient forms of lighting.
Switching to CFLs and LEDs throughout your home, using natural light wherever possible, and turning lights off when not in use could make a big difference to your power bills.
The three main factors to consider with selecting energy efficient lighting are:
- The power of the light – the cost of running a light is directly related to the wattage of the light globe or lamp, so the higher the wattage, the higher the running cost; therefore, using low-energy CFLs or LEDs will result in significantly lower running costs compared to incandescent or halogen lighting.
- How long you use lighting for – the longer your lights are left on, the higher your running costs will be, so switch lights off when not in use to keep your lighting energy costs down.
- Light fittings – using downlights rather than pendant or fluorescent fittings will mean you have to install more lights, so your overall lighting energy use and running costs will be higher
What are the benefits of energy efficient lighting?
Although CFLs and LEDs can be more expensive to purchase initially, they use up to 80% less energy to produce the same amount of light and they also cost you less to run. This means that you’ll change them less often, so they will end up being more cost effective in the long run.
One of the main reasons they are so efficient is that most of their energy is used to solely create light, rather than creating light and heat, which is what less efficient forms of lighting do.
Halogen lighting is available in either low voltage (12V) or 240V models, but don't be fooled – low voltage doesn't mean low energy use!
