Choosing the right light bulb is just as important as choosing your light fixture or shade as they can give your room ambience and character. This guide highlights the key things to consider to help you choose the perfect bulbs for your home.

Selecting the shape

Pick a bulb shape that gives you both the look and light spread that works best in your room.

Choosing the technology

The three main technologies for light bulbs are Halogen, Energy Saving (CFL) and LED. They all have different lifespans and energy saving abilities, so here’s a short guide on the differences between them.

Select the brightness level

Lumens vs Wattage

Wattage is the amount of power needed to light a bulb. Lumens refer to the level of brightness that the bulb produces.

Traditionally, a higher wattage always meant a brighter bulb. However, due to the introduction of newer technologies (Halogen, Energy Savers (CFL) and LED), you can now produce the same amount of light using far less energy (wattage) and money. To know how much light a bulb produces, we now use lumens to measure brightness.

Although lumens and wattage do not directly correlate, the below table will give you a good indication of which bulb you need. 

A helpful example:

To find a bulb that produces the same amount of light as an old 60W bulb, you will need any one of the below:

  • LED 10W bulb
  • Energy Saving (CFL) 15W bulb
  • Halogen 42W bulb
