To choose the right LED lamp for your home, it is recommended to consider some essential points, such as light output or color temperature. These are important and useful criteria before buying.

Choose the light taking into account the light output:

Incandescent light if the light output and power consumption of light and a spot were previously associated, it is now possible to consume only 4.5W / h with an LED light. A 40W standard produces 40W of light. It is, therefore, possible to save money by choosing the right lamp. The luminous power is expressed in luminous flux, itself in Lumens (LM) which means that The quantity of light emitted is defined by this flux.

To help know the equivalence of Lumen (LED lights) in Watt (conventional lights), there is a European standard on the connections lm and W. Here are some correspondences:

Choose the light considering the color temperature:

Formerly, lights and incandescent spots were presented in one shade: warm white tending towards yellow. Today, it is possible to find LED lights and spotlights of various colors.

Daylight is called "cold light" and is called "warm" when it turns yellow in the morning or evening. For lamps, we can know if the light is cold or hot thanks to the inscriptions on the packaging.

As for the temperature, it is expressed in ° K (degrees Kelvin). The daylight is therefore 6500 ° K and the one tending towards the blue is about 10000 ° K. This one will be cold. As for white, it projects a color temperature of 4000 ° K if the cold white emits up to 5000 ° K and the industrial white more than 6000 ° K. Otherwise, when a light turns yellow-orange, the temperature is 0 ° K.

To give a room a touch of warmth, it is advisable to opt for the warm white, with a color temperature that can go to 2200 ° K and more. To illuminate the corridors, the stairs and other places of passage, the cold white will be more adapted.
