Not all light bulbs are created equal and considering lighting contributes to around 10% of the household power bill it is worthwhile thinking twice about which bulbs you buy.
There are three main types of light bulb: incandescent, Light Emitting Diode (LED) and Compact Fluorescent Lights (CFL). Halogen is also common, which is a modern incandescent light bulb.
LED bulbs don't have a filament like a traditional light bulb.
Energy saving bulbs
CFL bulbs contain a gas that when excited by electricity produces invisible ultraviolet light (UV), which turns into visible light when it hits a white coating inside the bulb. CFL's contain a small amount of mercury, so take extra care when handling and disposing of them.
Incandescent light bulbs are traditional light bulbs. They use a filament that is heated until it glows white hot producing light. They are less efficient as they produce more heat than light.
Electricity saving tips
- Appliances that use standby power can account for up to 7% of your power bill. TVs, stereos and DVD players don’t need to be on all the time. Plug them all into a multi-plug board so they can all be turned offproperly with one easy flick of the switch.
- To keep your towel warm and dry all year round AND save on power opt for a timer. You’ll avoid unnecessary heating and could save up to two thirds of the cost by not leaving it on continuously.
- Get into the habit of turning the light off once you leave the room.
