Changing our lights is currently one of the fastest and most convenient ways of reducing the energy demands of our buildings. Many years have passed since the light bulb was invented in 1879. The first alternative to it was the energy-saving alternating current tube invented by Nikola Tesla for the World Fair in Chicago in 1893.
The use of this technology was limited to tubes, to come back under Tesla in the form of compact fluorescent lamps (CFL). Compared with classic light bulbs, these promised savings in the initial phase of approximately 70% Apart from their less-than-ideal impact on human health, they suffer from strong degradation of light output as their electricity consumption increases. More recently, LED light sources have been introduced which give savings of up to an almost unbelievable 90% compared with classic light bulbs and 50% compared with energy-saving light bulbs.
A simple exchange of light bulbs can save you several thousand crowns a year, without any change in your comfort level.
LED lights have many advantages. Those most appreciated include:
