- On average, lighting can account for 7% of your energy usage^.
- Energy-saving light emitting diode (LED) lamps are the most efficient form of lighting. They may cost more up front but will cost a lot less to run. Quality LEDs should last at least 25,000 hours compared to 6-8,000 hours for a compact fluorescent lamp (CFL).
- Last to leave the room? Always switch off the lights.
- Dusty or dirty lights can dim lighting by up to half. Spend a little energy of your own to clean light globes, fittings, reflectors and lampshades.
- Halogen lights are some of the most expensive to run, so try using them as little as possible.
- Painting interior walls a lighter colour will reflect light better and reduce the need for additional lighting.
