Qu'est ce qu'un Lumen ?

Qu'est ce qu'un Lumen ?

Le Lumen est tous simplement l'unité de mesure du flux lumineux dégagé par l'ampoule ou l'accessoire led.

 

Les produits en version High Lumens ou plus souvent appelé HIGH EFFICIENT, dispose d'un flux lumineux (lumen) supérieur de 20% à 30% par rapport à un produit led en version basic, pour la même consommation énergétique en Watts.

Les Produits led high lumens sont des leds SMD ou COB poussées au maximum de leur puissance et recouverte d'une lentille 2D ou 3D qui permet la concentration de la lumière.

Seuls défauts les leds HIGH EFFICIENT disposent généralement d'un angle d'éclairage plus faible, elles supportent aussi moins bien les différentes variations de tensions électrique.

    Going to graduate school was a positive decision for me. I enjoyed the coursework, the presentations, the fellow students, and the professors. And since my company reimbursed 100% of the tuition, the only cost that I had to pay on my own was for books and supplies. Otherwise, I received a free master’s degree. All that I had to invest was my time. https://www.treeservicebakersfield.co

    The main aim of allotting broadcasting rights to a maximum number of media outlets as possible is because the Olympic Charter states that “The IOC takes all necessary steps in order to ensure the fullest coverage by the different media and the widest possible audience in the world for the Olympic Games.” 2021 olympics

    If we are going to talk about murals, it is a harsh reality that there are people who do not appreciate artworks like this. Rip Wheeler Jacket I feel bad, but there is less that I can do; I want them to realize that murals are beautiful and worth appreciating. But I simply don't know where to start. Sometimes, I think of writing as my way to influence people to appraiser things that should be appreciated. I don't know if that is going to be effective, but I want to give it a try.
