What is a Lumen?
Lighting—it’s all about lumens. But what are lumens, exactly? And how do you understand what are lumens in light bulbs and light fixtures? In addition to being the Internet’s premier modern lighting and design store (hey, that’s us!), lumens is now THE way to find out how bright a lighted bulb or an LED lighting fixture is.

The Lumens definition is: “a unit of luminous flux in the International System of Units, that is equal to the amount of light given out through a solid angle by a source of one candela intensity radiating equally in all directions”

In short…

Lumens equals brightness!
