Energy Efficient Lighting
Top tips for lighting your home
LED (light-emitting diode) globes generally use the least amount of electricity
Think lumens, not watts – they are the new measurement
You don't need high wattage to get a bright light
If you have CFL (compact fluorescent lamp) light bulbs in a room that's used frequently, change them to LEDs. Otherwise, wait for them to stop working then replace them with LEDs.
Choosing a bulb
Light bulb technology has changed quickly and, with so many options, it can be confusing.
Types of light bulbs
LED bulbs. These use the least amount of electricity. They are more expensive than CFLs but will last longer. They are suited to most lighting situations and you can buy them at supermarkets, hardware stores, and lighting shops.
Compact fluorescent lamps (CFLs). These are mini versions of fluorescent tubes and are usually swirly. They are reasonably inexpensive and are more energy-efficient than halogen and incandescent bulbs. They contain small amounts of mercury, so be careful when throwing them away.
Halogen lights. This type of incandescent bulb will be banned in Australia from September 2020. Changing halogen lights to led should be done quickly.
Incandescent bulbs. These bulbs create electric light with a wire filament heated until it glows. They have been mostly phased out since 2009 but are sold as a specialty.
