How to determine how bright a light is?

When we want to assess how bright a light is, we will refer to the lumens(lm) of the light source. Lumens are a measure of the total amount of visible light for a light source. The higher the number, the brighter the light. For traditional incandescent globes, the general rule is the higher the wattage the brighter the light. But with LED advancement in recent years being more energy efficient, the best way to assess the brightness of a light is to look at the lumens.
