How much more efficient are LED light bulbs?

04 Jan How much more efficient are LED light bulbs?

LED light bulbs are available in all sizes, from A15 to GU10. They are the most energy efficient light bulbs on the market, however they do face stiff competition from low-energy halogen light bulbs, as well as Compact Fluorescent Lights (CFL).

LED light bulbs have gained in popularity these last ten years because they boast a lifespan in excess of 25 years. Compare that to a standard halogen light, which will last around 3 years if you are lucky, and you can see that the total cost of ownership is lower with LEDs.

But how much more energy efficient are they?

For the sake of comparison, let’s pit an ECO Halogen 50W GU10 against an LED 50W GU10:

ECO Halogen 50W GU10 vs. LED 50W GU10

A halogen 50W GU10 light bulb has an energy rating of D and will consume around 1,200 kWh of electricity over 24,000 hours. The cost of electricity per kWh is £180.00 and you will have to replace the bulb 12 times over 24,000 hours. This will cost around £18.00.

An LED 50W GU10 light bulb has an energy rating of A or A+ and will consume around 120 kWh of electricity over 24,000 hours. The cost of electricity per kWh is £18.00. Because of its reliability, you don’t have to replace the bulb at all, saving you £18.00.

This comparison shows that over its lifetime, an LED light bulb will save you £175. That’s despite the higher purchase cost of the LED bulb.

However, it’s also important to remember that LED light bulbs have dropped in price over the last few years. You can pick up a pack of 6 GU10 bulbs from ASDA now for £18, or grab Philips LED bulbs for around £3 each online. And unless you are unfortunate enough to buy a faulty unit, you won’t have to buy anymore for over 25 years.

Another benefit to LED lighting is the colour spectrum on offer. While halogen bulbs are always on the warmer end of the scale, LED bulbs can be either warm or cool all the way up to 8000k (that’s bright white light). A cooler light source is ideal for office environments and for environments that don’t have a great source of natural light. LED light bulbs also give off very little heat, so they are a better choice of lighting near sources of ignition.

Overall, LED light bulbs can save you a lot of money and for the best savings, professional installation is recommended. We offer these services, so give us a call on Freephone 0800 9788 168 or 0113 8941968 today to find out more.
