The classic incandescent lamp, invented in 1879 by Joseph Swan and improved by the work of Thomas Edison, produces light by carrying an incandescent filament of tungsten. If it is still present today in the DIY department stores, it will disappear in the coming years. Indeed, with the arrival of its much more ecological and sustainable competitors, the incandescent lamp is pointed out as being very energy-consuming, and it is gradually becoming obsolete. In France, the switch to low-consumption lamps has saved some 8 billion kWh, or 1.5% of national electricity consumption in recent years. Significant energy savings for both households and the environment.

New generation lamps

There are 3 families of lamps: incandescent lamps (so-called "classic" filament lamps), discharge lamps (fluorescent or commonly called "low consumption") and LED (electroluminescent or more commonly LED lamp). The latter is a type of electric lamp that uses light emitting diodes. Today, the lamp has become a decorative element in its own right, in addition to its practical function. It not only contributes to the style of a room, but its arrangement and the distribution of light sources also create an atmosphere while playing with the interior architecture.

Low consumption lamps

Ecological par excellence, compact fluorescent lamps - or low consumption - are much more efficient than incandescent lamps. In summary, they are a miniature adaptation of the famous fluorescent tube, which had its heyday in household kitchens and bathrooms during the 1980s. Having no need to produce heat to light, compact fluorescents have a lifespan of 9000 hours on average, 13 times more than a conventional lamp. Although a little more expensive to buy than their incandescent rivals, they prove to be more profitable in the long term thanks to their service life and their excellent lighting performance.

LED lamps

LED lamps have been on the consumer market for about 4 years. They reach their maximum lighting power in 0.5 seconds (heating time of internal components), which places their performance high above compact fluorescent lamps and remains almost invisible to the user. With low power consumption and a longer life than incandescent and compact fluorescent lamps (more than 50,000 hours!), The LED lamp is the ecological champion of lighting. Its end of life is characterized by a gradual decrease in its brightness, and not by a sudden breakdown like its rivals. However, with a purchase price 2 to 3 times higher than for a conventional lamp and a high sensitivity to high temperatures, the LED lamp does not only have advantages.

    I apologise, but, in my opinion, you commit an error. I can defend the position. Write to me in PM, we will talk.
