Do you still use old electric candles? It might not be worth it

Do they shine still have ancient lightbulb candles on your window or Christmas tree? Old, high-quality light sets may last for decades and may already have sentimental value.

Still, it might be worth replacing them with new ones, where the light is produced by LEDs.

Light bulbs or halogen bulbs often use about ten times more electricity compared to LEDs that produce a similar amount of light. It is due to the fact that in light bulbs, the vast majority of electricity is converted into heat and only a small part of the energy is emitted as light.

In LEDs, on the other hand, the vast majority of energy is radiated as light and only a small amount of waste heat is generated.

Helsinki the city’s energy company Helen’s calculation According to A light bulb candle, on the other hand, consumes electricity for 3.02 euros.

You can get a window candlestick for 15–20 euros, which means you can save the price of a new candlestick after using it for about six months.

In general, the use of decorative lights with LEDs puts quite a small burden on the electricity bill. According to Helen’s calculation, the whole, which includes a 12-meter light set, a window candle and Christmas tree lights, consumes 3.5 kilowatt hours of electricity per month, which would cost 1.75 euros, according to Helen.

Energy use promoting efficiency According to Motiva in outdoor light sets, the energy consumption of LEDs was less than a tenth of the consumption of a similar type of light bulb set. Motiva measured the actual consumption of the light sets.

When using a long series of outdoor lights, LED lights quickly save a considerable amount. According to Motiva, the electricity used by the light bulb light cable (price 0.20 euros/kWh) would cost about 45 euros in 100 days. The electricity consumed by a similar type of LED lighting set would cost only 3.70 euros.

The value of the electricity used by the decorative lights depends on the own price of electricity and electricity transmission. The consumption of lights can be reduced by timing the lights to be on only part of the day.
