Energy saving light bulb facts

As a rule of thumb, a 20-watt energy saving bulb should produce about as much light output as a 100-watt standard bulb – good models produce more.

That means if you replace an ordinary bulb with a quality energy saving bulb, you’ll only use about one-fifth as much electricity – and still have at least as much light as before.

For each ordinary bulb you replace with an energy saving bulb, at current electricity prices it has been estimated you’ll save around $120 over the life of the bulb (8000 hours).

How long do energy saving bulbs last?
An energy saving bulb should last about 5000 to 10,000 hours, whereas an ordinary bulb will generally burn out at around 1000 hours. Used for 3 hours a day, an energy saving bulb should last about 10 years.

Don’t energy saving bulbs produce harsh light?
Not necessarily. Unlike ordinary bulbs, energy saving bulbs come in a range of whites.

If you want lighting that’s similar to an ordinary bulb, say for places where people relax – like lounges – look for “warm white” on the packaging.

In kitchens, bathrooms, laundries and work areas, some people like a ‘cooler bluish-white’ light. If you want this colour, look for “cool white” or “cool daylight” on the packaging.

Don’t energy saving bulbs cost more than ordinary bulbs?
Energy saving bulbs cost more to buy than ordinary bulbs. But a $6 high quality energy saving bulb should last longer than six $1 ordinary bulbs – and you won’t have the hassle of changing bulbs as often.

Buying energy saving bulbs will work out cheaper in the long run. And, energy saving bulbs use 80 percent less power over their life so you’ll save money on electricity use.

From time to time the Electricity Commission subsidises high quality energy saving bulbs. During those times, the subsidised bulbs can be purchased for substantially less than their normal price.

Do they flicker like fluorescent tubes do?
No. Good-quality energy saving bulbs don’t flicker.

Are there any other advantages of energy saving bulbs?
They run cooler than ordinary bulbs, so light fittings don’t get as hot. They are available in a variety of shapes and sizes.
