A small change that adds up to a big difference
LED light bulbs use up to 85% less electricity than traditional incandescent or halogen bulbs and can last 15 times longer. They cost more upfront – but the long-term savings are worth it.
- Wide range of looks and styles
- Most bulbs cost less than $10, some just $3 or less
- Can save $100-$300 in running costs over the life of the bulb
- Good quality lighting
- Instant brightness
There’s an LED for every room in the house
LEDs come in different types including standard light bulbs, spotlights, candles and recessed downlights. You can choose dimmable or non-dimmable bulbs. Some can change their light colour or brightness even without a dimmer switch.
Choose the right LED bulb
BaseFor standard bulbs, check if you need a bayonet or screw fitting. To replace halogen spotlights, check if you need a low-voltage (12 V) MR16 (also called GU5.3) bulb with two sharp pins, or a mains-voltage (240 V) GU10 bulb with two studs.
BrightnessLED packaging shows light output in lumens, usually with the equivalent wattage of an incandescent bulb. Chances are the LED will actually appear brighter.
ColourWarm white is more comfortable in homes. Cool white works best where contrast is important, such as workshops and garages.
Points to watch
- LEDs shouldn't be used in enclosed fixtures where the bulb is fully encased in plastic or glass, such as some porch lights. LEDs need good ventilation for a long life – if they get too hot, they may fail.
- For recessed downlights, it’s best to replace the whole fitting rather than just the bulb.
- Hold onto your receipt. With LEDs costing a bit more to buy, keep your receipts in case you happen to buy a dud.
