What is a Lumen? What’s the Difference Between it and a Watt?

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? 

lumens is now THE way to find out how bright a lighted bulb or integrated LED lighting fixture is. And if you want a fixture with bright, luminous , it's the key to choosing the perfect piece for your lighting .

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!

And watts do not. Not that watts are bad, but they measure energy use, not light output. With new, energy-efficient LED technology, we can no longer rely upon wattage to indicate how bright a bulb is . See how to measure lumens below:


HOW MANY LUMENS DO YOU NEED?
MORE LUMENS = MORE LIGHT



Use the chart above to determine exactly how many lumens are in a watt and vice versa. This should provide you with a good understanding of how bright 450 lumens is vs. a fixture with 5800 lumens
