Electricity shortage: what do LED bulbs really consume and really reduce your bill?

With the energy crisis looming this winter, it is advisable to prefer LED bulbs to conventional bulbs. But are they really cheaper?

With the sobriety efforts required of the French in the face of the energy crisis expected this winter, it is important to know whether the use of LED bulbs over conventional bulbs really changes the situation.

To find out, you already need to understand how the two types of light bulbs differ. The classic light bulbs they work with incandescence so that they warm up. The 90% electricity used is for heat and 10% for lighting. So that’s a lot of wasted energy.

LEDs, on the other hand, consume only to produce light, so it is preferable to use LED bulbs which are much cheaper to use.

Indicative labeling

On the packaging of the LED bulbs it is indicated the number of watts that the LED bulb consumes and its equivalence from the point of view of performance with a conventional bulb.

That is to say that the indication on the label of “9 W = 60 W” for example, shows that the power consumed is only 9 watts for the LED bulb for a restored power of 60 watts. A conventional light bulb would then have consumed 60 watts for the same efficiency.

A comparative calculation

To calculate how much a light bulb consumes, the calculation is simple. It is necessary to calculate with the average price of Kwh estimated in France a € 0.174 in 2022 for EDF’s basic regulated tariff according to the electricity supplier website.

It is therefore sufficient to make the following calculation to estimate the electrical consumption: the number of hours of operation x the number of days of operation x the power of the device in watts / 1,000, as provided by the Engie website.

That gives for an average number of hours of use for LED bulb of 3 hours per year a consumption of 9,855 Kwh, which is equivalent to an average price from 2 € for one LED bulb used for three hours a day.

On the other hand, for a classic light bulb equivalent to the same performance, so 60 watts, the price amounts to almost 12 €.

An LED bulb is therefore more economical in terms of consumption than a conventional bulb.

With multiple bulbs working in the house, it is therefore preferable to have LEDs. The bill can thus easily be reduced by one hundred euros per year …

And even if their price is a bit higher, they work for a longer period of time.

Of course, the price varies according to the subscription and options of the energy supplier.
