Saving Money With LEDs

Saving Money With LEDs

With the economic crisis a few years ago, people have had to tighten their belts drastically, lowering their outgoing finances as much as possible. However, LED lighting has quite often been over looked as a money saving technique, due mainly to the fact that by purchasing more products, you can not possibly be saving more money. Whilst logical to a certain extent, when you look into every factor, and work out the costs a bit more in depth, it can actually be a very worthwhile investment.

It is also worth noting, that in recent years, the price of LEDs have lowered substantially, and although they still cost more than their halogen and compact fluorescent counterparts, they have become a more viable option.

The Maths:

(Please Note: Our calculations are based on an average price of 14.05p/kWh that has been taken from the energy saving trust’s website. This average was calculated during February 2015 based on households in England, Scotland and Wales.)

For this calculation, we are going assume a household has 10x 60w Incandescent globes as the only lighting source, and we will be replacing them with 10x 9w SMD LED Globes. We will also assume that the average amount of time the lights are switched on per day is 5 hours.

Comparison
60w Incandescent Globe:

5 hours x 365 days = 1825 hours (1 years hourly usage)

60W x 10 = 600W (Total lighting power)

600W / 1000W = 0.6 kWh (1 hours lighting usage)

14.05p/kWh x 0.6 kWh = 8.43p (The cost of all lights turned on for 1 hour)

1825 hours x 8.43p = £153.85 (Yearly lighting costs rounded up to the nearest pence)

9W SMD LED Globe:

5 hours x 365 days = 1825 hours (1 years hourly usage)

9W x 10 = 90W (Total lighting power)

90W / 1000W = 0.09 kWh (1 hours lighting usage)

14.05p/kWh x 0.09kWh = 1.2645p (The cost of all lights turned on for 1 hour)

1825 hours x 1.2645p = £23.08 (Yearly lighting costs rounded up to the nearest pence)

So by switching, you could save £130.77 each year. It is also worth pointing out that the average life of an incandescent is roughly 1200 hours, not enough to cover a year in this instance, whereas the 9W LED has an average life of 30,000 hours! Theoretically, this means they could last 16 years! That works out as £2092.32 worth of savings.

As you can see, the amount of electricity saved per year is quite substantial. Not only does this mean your saving money, it’ll also help reduce your carbon footprint!
