Change to energy efficient light bulbs

Incandescent lighting is the most energy-inefficient and expensive to run of all household lighting options. Switching to a LED light from a standard globe can save you $30 per year* per globe. They also last much longer than standard bulbs. The Energy Rating website has more detailed information on lighting options, and a light bulb buyer’s guide includes a handy light globe conversion table to help you select the right lighting for your needs. *Based on three hours of use per day, 350 days per year at 32 cents/kWh.

The NSW Government has launched a lighting upgrade offer for households. The purpose of the offer is to help eligible households replace old lights with new LED lights. The cost of the LED lights and the fee for installation is subsidised. Currently, the offer targets the replacement of halogen downlights with LED downlights. If a household replaces 20 halogen downlights, they could save up to $210 off their bills every year. More information here.

Switch off your lights

Try installing motion sensing lights in areas such as bathrooms, corridors, entrances, laundry and kitchen. Doing this will take the effort out of energy saving.

Green your outdoor lighting

User timers, motion sensors or solar powered lighting for all garden and security lights. Make sure these lights are energy efficient LEDs.

Keep it simple - single lights

Switch to a single bright light instead of a multi-bulb fitting. Avoid using multiple-bulb fittings, as this is an inefficient form of lighting. Around six 25-watt bulbs are required to produce the equivalent light output of a single 100-watt bulb.

Helpful tips to keep your lighting costs down:

  • Avoid having several lights activated by one switch. Use separate switches for each light.
  • Use the lowest wattage light needed to adequately light an area.
  • Avoid using downlights, as several are needed to light an average-sized room. They can also lead to heat loss through the recessed holes where they sit in the ceiling. For recessed downlights you must remember to give at least 50mm clearance between the lights and bulk insulation material and 200mm clearance between the lights and any combustible building element.
