A very common question that we are asked is what does lm mean in LED lighting terminology?

 

Lm stands for lumens. Lumens is the measurement of brightness that an LED product gives out as perceived by the human eye. So, essentially, how bright a light is. It is important to consider the lumen output when purchasing an LED product and think about where this light will be placed and what it will be used for. For example, if a light is going to be used as your main task light in a room such as the kitchen you will need to ensure it has a higher lumen output. If you are using a light to create ambience in a room then it can have a lower lumen output.

 

The symbol for lumens is: lm, for example: 260lm
