The UV then hits a phosphor lining inside the tube, which excites the phosphor and creates light that we can see. The vapour gets excited by the charge and creates invisible ultraviolet (UV) light. Fluorescent lightsīoth CFL and fluorescent tubes work in the same way - by generating an electric charge inside a glass tube filled with mercury vapour.

Halogen gas speeds up the heating process, meaning the bulb can get brighter using less electricity and lasts longer (as the gas protects the filament). Halogen light bulbsĪ halogen light bulb lights up in the same way as an incandescent one does - through the heating up of the tungsten filament - however, a halogen bulb also contains halogen gas. However, the more energy used the more heat that is produced. The more energy, or watts that run through the tungsten filament, the more light (lumens) is produced.

Incandescent light bulbs create light by heating a wire, known as the tungsten filament to a high temperature by running an electric current through it until it glows brightly. One thing remains the same though - a bulb that produces more heat for the same light output is simply less efficient. This may seem like a simple question, but the answer depends on the type of light bulb, as each works slightly differently than another.

Light Emitting Diode, otherwise known as LED - This is the most energy-efficient, and cost-effective, option available.īOOK MELBOURNE'S LIGHTING SPECIALISTS How does a light bulb work?.

Compact Fluorescent Lamps, otherwise known as CFL - Are more energy efficient than both halogen and incandescent, and less costly to run.

Halogen - Produces light in a very similar way to incandescent lights, however, uses less energy to do it.

A phase-out of incandescent lights commenced in 2009.

Incandescent - The most common light for over 100 years, however, they use a lot of electricity and don't last very long.

There are four main types of light bulbs: What are the different types of light bulbs? If you would like any further information, give 1st Call Electrical a call on 1300 016 671 today. There are so many light bulbs to choose from, with differing colours, styles, brightness and sizes, so how do you know what to choose?īecause the simple task of choosing a light bulb just isn't simple anymore, we have put together some information regarding the different light bulb types, how they work and how to compare them against one another.

So you want to change a light bulb in your home or workplace, and it used to be easy.
