What is the lux?
Lux is a unit used to measure the intensity of light hitting a surface, typically a wall or floor in a lighting design. One lux is equivalent to one lumen per square meter. They differ from lumens, which measure the brightness of the light source.
1 LUX = 1 Lumen / m2
What does this actually mean for you? Well imagine you buy a 400 lumen led light and put it in a room with 10m2 of surface area inside. A little toilet or store room for example. Putting that into our equation, the room is therefore on average getting a light intensity of 40 lux. Put that same bulb into a larger room with say, 20m2 of surface area, and all of a sudden the lux level will drop to 20 lux. This kind of demonstrates the obvious in that the bigger the room, the more you will need to create the right light levels. That much is obvious, but when you factor in natural light, the dimensions of the room, the required use of the room and other factors, suddenly having a unit like lux to be able to compare light intensity is very useful.
You can use lux to create a standard that can be employed across different buildings and usages, suddenly allowing you to compare the quality of the lighting in one building to another, or assessing whether the led light is sufficient for the purpose it was designed for. If you get a lighting design carried out by an expert company like Fanguang Lighting, we can show you the brightest spots in a room and areas where you need more lighting, making sure that each area of the property is sufficiently and correctly lighted.
