How much you really save by switching to LED lights

Will LED Lights Save Money?

The most frequently asked question in lighting solutions is, “Will LED lights save money?” The answer is that LED lights consume around £80.00 of power over a 20+ year lifespan. CFL bulbs consume in excess of £120.00 over the same period and must be replaced every 5,000 hours. This gives LED lights the edge when it comes to net savings on both energy and lifespan.

How LED light bulbs save you money

The cost saving provided by LED lighting is due to two factors:

  1. LEDs require much less electricity to power than both traditional incandescent and halogen light bulbs, and energy efficient light bulbs (CFLs).
  2. They last much longer than their incandescent, halogen and CFL equivalents.

For example, a 60W halogen light bulb would be replaced with a 9W LED. That’s a reduction of 85% in electricity consumption. The LED bulb will also last for over 20,000 hours, as opposed to 2,000 hours for the halogen – ten times longer!

What about CFL bulbs? Using the same example, a 60W halogen equivalent would be an 11W CFL bulb, so the reduction in electricity consumption from CFL to LED would be 18%. A good quality CFL should last for around 8,000 hours, which is still less than half of the LED equivalent.

Calculate the cost savings of LED light bulbs

Now that we know why LED light bulbs are cheaper to run, we can now look at how you can calculate the amount of money you can expect to save by switching to LEDs.

The information you need to work this out is:

1. The wattage of your current light bulbs and spotlights.
2. The average length of time each light bulb is in use for per day.
3. Your current electricity rate per kilowatt hour (kWh, kW-h or kW h). The UK average at the time of writing is 14.71 pence p/kWh if paying by direct debit.
4. The cost of replacing each bulb with an LED equivalent.

Testimonial Fairhaven Golf Club

Following several recommendations, we engaged with Airis to deliver a solar project here at Fairhaven Golf Club. As an organisation, we prioritise sustainability throughout our working practices and to partner with a company that shared these values was most beneficial to the process. The project will see our annual grid consumption reduce by over 12% resulting in around 21,000 kWh of energy each year being generated. During the planning stages, we encountered several issues which the team at Airis helped to resolve. Their understanding, flexibility and practice applications made the whole process seamless. We could not recommend Airis more highly.

The change to LED has been a switch we’ve been considering for a few years. It was just a matter of finding the right partner with the expertise to deliver it across all our sites. Airis Energy Solutions not only made it happen, but they upgraded 29 of our sites simultaneously with upfront costs kept to a bare minimum. The results speak for themselves.

We sourced Airis Energy Solutions alongside the Green Business Fund / Carbon Trust to install a full school LED Smart Lighting system. All our lighting was extremely outdated and was failing more frequently, at a significant cost each time. There is no capital outlay and the installation of new lights was a very efficient process, with all the old lighting being taken off-site afterwards. It has significantly improved the appearance around school, has reduced our maintenance costs to zero, reduced our CO2 emissions and will reduce our energy consumption over time.

From start to finish Dave and his colleagues were fantastic to deal with. Very straight forward and completely transparent about the service. We are extremely pleased with the outcome and would happily recommend Airis to anyone who is interested. We had no disruption to our very busy factory and the fitters could not do enough. All in all, an excellent job!
