The symbol for lumens is lm.
Lumens (lm) represent the SI derived unit of luminous flux. Luminous flux is a measure of the total amount of visible light emitted by a light source. It quantifies the "brightness" of the light source as perceived by the human eye.
Here's a breakdown:
- Lumen (lm): The unit of measurement for luminous flux.
- Luminous Flux: The total amount of visible light emitted by a source. A higher lumen value indicates a brighter light source.
Essentially, the 'lm' symbol helps us quickly and easily communicate the amount of light a bulb or fixture produces, making it simple to compare different lighting options.
