Why switch to LED light bulbs?

An LED light bulb typically uses up to 90% less energy than regular incandescent or halogen light bulbs and lasts far longer. This opens up savings in two ways:

  1. On your electricity bill
  2. On having to change your light bulbs less often

In addition to saving you money, LED light bulbs also help you save the planet because they use less energy and are often recyclable. Read more about the benefits of swapping out your light bulbs for LED ones in our article, Why Now Is THE TIME To Switch To LED Light Bulbs.

The most common light bulb alternatives

Incandescent bulbs were the most common type of light bulb found in the home for many decades. Although they used to be the cheapest type of bulb to buy, they were not energy efficient and needed replacing far more often. It is for those reasons that incandescent bulbs have been phased out in many countries around the world.

Halogen bulbs are a variation on the incandescent bulb and are said to use between 20-30% less energy. They are now the cheapest light bulb you can buy, but have a shorter lifespan than CFL and LED bulbs.

CFL bulbs (compact fluorescent lamp) are a type of energy-saving bulb and are said to use between 60-80% less energy than a standard incandescent bulb. They also have a far longer lifespan.

Working out your CO2 saving

The LED Saving Calculator produces a calculation for CO2 emissions. In order to calculate this figure, we use the DECC conversion factor of 0.542 kg CO2 saved for each kWh (produced from a carbon-free source).
