The lumen is a unit of measurement for the brightness of light. If a light bulb is blindingly bright, it produces a lot of lumens.
Lumens are a measure of the total amount of visible light emitted by a lamp or light source. They indicate the brightness of the light and are denoted by the symbol “lm”. Lumens provide a more accurate measure of light output compared to watts, which only indicate energy consumption.
What's a Lumen? Lumens measure how much light you are getting from a bulb. More lumens means it's a brighter light; fewer lumens means it's a dimmer light. Lumens are to light what. Pounds are to bananas; Gallons are to milk; Lumens let you buy the amount of light you want. So when buying light bulbs, think lumens, not watts.
The lumen is a measure of light defined by the International System of Units (SI). It describes the output of devices that emit light visible to the human eye. While lumens pertain to all light-emitting objects, ANSI lumens are a slightly different way of measuring light specific to projectors.
