• Pros and cons of different light bulbs

What you should look for when buying light bulbs and the pros and cons of different types. Many people choose light bulbs according to the selection available in their local supermarket. We'd like to change that, because choosing the right light bulbs for your home can save you money, create visual pleasure and preserve energy. To help you select the right ones, we have outlined light bulb features you should consider as well as the pros and cons of different types.

Features to consider

Energy efficiency

Larger houses, with more rooms and more light fittings, have led to an increase in energy consumption across Australia. The most energy-efficient solution is to make better use of natural light through the effective placement of north-facing windows, skylights and the creation of a light, reflective colour scheme. Before purchasing light bulbs, consider where they will be used, how frequently and for what kind of duration.

Watts

The standard measurement for electricity is watts. When buying a light bulb it is best to select one with the same number of watts as the bulb you are replacing. A light bulb with fewer watts than your existing globe will produce a weaker light.

Life

This describes the number of hours a light bulb will last. Make sure you check this before you buy – especially for light fittings in hard-to-reach places that you won't want to replace regularly.

Existing light fitting

Not all light fittings are the same. Take your old light bulb with you to the shop to ensure an exact match.

Clear or frosted glass

Choosing clear rather than frosted glass will change how the light looks in a room. It's your personal choice.

Different types of light bulbs

Incandescent

Incandescent light bulbs are the most popular – you probably use them in your home now. These lights have a filament that's heated until it glows. This glow is what provides the light.

Halogen

Halogen light bulbs use the same technology as incandescent light bulbs, however it uses halogen gas, ignited by electricity to create the light.

Fluorescent

A phosphor coating that glows inside the tube of fluorescent lights is what makes them work. There are two main types: tubular lamps – these are the long traditional type that require a special fitting; and compact fluorescent lamps (CFLs) – these are designed to fit into conventional fittings.

LED

LED stands for light omitting diode. They generate light not through heat but the electronic movement of particles. LEDs are also used for many other applications including stereo lights, microwave ovens, digital watches and calculators
