Definition: LUX

What is lux?

You have probably come across the term a few times when looking for information on lighting - lux. But what is it exactly? Lux literally means light in the Latin language. The term indicates the illuminance. This means that it represents how much light a particular lamp actually provides in the desired location. This is not to be confused with the brightness of the light or the density of the light beam. The density, for example, is indicated by the term candela and the amount of light emitted by a lamp is indicated by the number of lumen.

Lux and lumen, what is the connection?

As mentioned earlier, the two terms are slightly different but they are closely related. The number of lux depends on the number of lumens; they are related. When a beam of light with a strength of one lumen shines on a surface that is exactly one square metre, it has a strength of one lux. In other words, one lux is equal to one lumen per square metre. If the lighting therefore has fewer lumens, this will certainly have an effect on the number of lux. So the terms do not mean the same thing, but they do influence each other.

What is the best thing to look for?

In addition to lumen and candela, there are of course terms such as wattage and ampere. But also the word volt you have probably already come across several times. All these terms are very important in the search for the best fitting LED lights. But what is the best thing to look for? The answer to that question is not so simple. It depends very much on the situation and the desired purpose of the lamp. The most important thing is not to focus on just one of the terms. They all say something different and one is more important than the other in a particular situation.
