Luminous Flux

Where you want your light.

Luminous Flux is the flow of light measured in lumens. With light bulbs, it provides an estimate of the apparent amount of light the bulb will produce. Depending on the application, much of an incandescents light is wasted because it's emitted in every direction. LED bulbs, on the other hand, put out directional light, sending all of the light exactly where it's needed.

 

In practical application, when buying a light bulb, we should look for bulbs which produce more light but consumes less energy. Understanding lumens as a measure of brightness makes it easier to select the most efficient bulb for your application.
