Now that Christmas is right around the corner, you may want to start putting up all the Christmas decorations and decorations. One of the most characteristic elements are Christmas lights, but taking into account the price of energy, you may have thought of spending this year with this light decoration.
Christmas lighting is not an excessive consumption, as long as LED or low consumption lights are used. You may still have thought that it is an expense that, although minor, is an expense that you cannot afford, but we are going to help you do the math so that you can verify that the amount of money you are going to spend is negligible.
LED lights cost little
Of course, if you want to save on your electricity bill this Christmas, you better control another series of expenses, since if you opt for LED lighting you won’t notice a big change in your usual bill.
The first thing to do is to know the voltage of our lights and how many watts (W) they consume. The next data to calculate is how long we would have them on. We can opt for a Solomonic measure such as 12 hours a day (after all, while you sleep or work you will not enjoy them).
Bearing in mind that a strip of 200 LEDs usually consumes about 6W per hour, we are going to use a couple of these strips as a reference (for example, for the tree and the nativity scene). Carrying out the relevant multiplications, the result that it gives us is 4,320 Wh, which must be converted to kilowatts (kW), dividing it by 1,000, since that is how the price comes from the electricity bill, they would give us 4.32 kWh .
Applied this figure to the cost for our pocket, with a rate figure of 0.19 euros per kWh, multiplying our consumption by the price (4.32 kWh x 0.19 euros per kWh) gives us 0.821 euros. Even adding taxes, the electricity tax which is currently 0.5% and VAT has been reduced to 5%. Therefore, 0.045 euros would have to be added. Which gives us a total of 0.866 euros. Yes, having the Christmas lights on 12 hours a day for 30 days will cost us about 86 cents.
Other advantages of LED Christmas lights
Although they are more expensive than incandescent bulbs, LED lights have a much longer life, are more efficient and ecological, since they reduce CO2 emissions by 80% and can also save up to 90% in electricity. electricity bill, as we have been able to verify in the previous calculation.
Another of its advantages in addition to the previous ones is that they illuminate, but do not heat. Not only do you not have to fear that the little ones in the house can touch them, but there is no danger of fire in case they come into contact with any surface by accident.
In addition, they burn out less easily than classic incandescent bulbs, and if one fails, the rest continue to work.
