What is lumen?
What is lumen and what is the difference with watt?
The definition of lumen is: ‘’a measure of the total "amount" of visible light in some defined beam or angle, or emitted from some source.’’ Or in short: Lumen equals brightness! And watts does not. Watts measure energy use and not the light output.
How do we translate wattage to lumens?
Lumens let you buy the amount of light you want. So when buying your new bulbs, think lumens, not watts.
