How much You can save when You Switch to LED light
If you think how to reduce the cost of electricity, one of the interesting options could be replacing typical incandescent lamps with LED technology.
Led bulbs are still more expensive than traditional lights but because LED bulbs consume less electricity to produce the same level of lights, that can make savings on electricity cost.
When we compare LED to other types of bulbs we can save around:
- 90% in comparison with traditional bulbs
- 60% in comparison with halogen light bulbs
So how much you can save in one year after you switch to LED technology?
After what time you will pay back the expenses incurred to replace the traditional LED bulbs?
LED bulbs are a few times more expensive than traditional ones but alerage lifetime LED bulb is 15000 hours (for example OSRAM E27 10W LED bulb) – traditional one is 1200 hours, that is 12.5 times more.
If we look at bulbs lifetime we will see that if you buy one LED bulb and you spent €4 – €5 you dont have to buy 12 traditional bulbs. (Some LED bulb lifetime is even more than 35000 hours)
To count the savings we use bellow example:
- 100 m2 flat with 3 bedrooms, 2 bathrooms, living room, kitchen, and hall
- 4-person family and period of 1 calendar year
- electricity price – €0.155
- traditional 75W bulbs
- OSRAM – LED bulb 10W, 1060 Lumens
In this example yearly savings is €139.74. If we count the cost of bulbs on lights.ie you can buy set of 3 OSRAM LED bulb E27 10W warm white 1060 for €12.9 (08/12/0218) so cost all new LED bulbs will be around €60 – that’s less than 6 first months savings.
This example shows that if you have a similar situation you can save around €80 in the first year and €140 on next years. Total hours of lights on per year is 7300 so new LED lamps should works from 8 to 40 years depens on room in this example, if average lifetime will be 10 years savings in total will be more than €1300.
So I think that this is something that we should think about, it is also a relatively small investment that can bring savings very quickly and for a long time.
