Potential LED Savings

The price of LED lightbulbs has fallen considerably since the technology was first introduced to the market a decade ago. While they are still more expensive to buy than traditional incandescent bulbs, they can save you a considerable amount of money over their lifetime.

The longer lifespans and energy-saving properties of LED bulbs mean that the upfront cost of buying them can be recouped in a matter of months. And, unlike traditional lightbulbs, once they're fitted, they won't need to be replaced for years.

To show you just how much money LED lightbulbs could save you, we have compared an LED product with a traditional incandescent equivalent. The LED bulb is a 5W GLS LED, costing £5.40 inc VAT, and the incandescent is a standard 40W GLS pearl, which costs £1.29.

The first cost to compare is for the bulbs themselves. The LED bulb has an average rated life of 20,000 hours, while the incandescent lasts for only 1,000. That means you would need to buy 20 of the incandescent bulbs to last the same amount of time as just one LED bulb. So while the LED bulb costs a lot more per unit, over its life it is incredibly cost effective.

Next to consider is the energy needed to power each bulb. One of the biggest benefits of the LED bulb is its energy efficiency; it produces the same light as an incandescent lightbulb with only a fraction of the power. In this case, the LED bulb uses only 5 watts of power, compared to the 40 watts that the incandescent bulb uses.

Thanks to the long life and the energy efficiency of the LED lightbulb, in this example it would take less than six months to recoup the upfront cost of buying it. In fact, the total cost of buying and running the LED bulb over its 20,000 hour life would be less than the cost alone of buying the equivalent 20 incandescent lightbulbs.

Over the life of the bulb, it amounts to an impressive saving of £153.40. Multiply that by the number of bulbs in your home and the potential savings are huge.
