What does Lumen output mean?

When you are shopping for LED lights, you should always look for lumens to be sure you’re getting the level of brightness or amount of lights, you want. Usually, we’ve been shopping for LED lights based on how much watts they consumed - not on how much lights they produced.


Lumens are a measure of the total amount of light is produced from lights source or bulbs. Higher lumens means brighter the light, fewer lumens means dimmed light. In the given table below that shows typical luminous flux for common incandescent bulbs with their equivalents.

How many Lumens output needs?


There is no firm answer – it'll depend upon a variety of things including; space size, the height of ceilings, colour scheme, sort of lamps & fitting, task areas. A standard 100W incandescent LED bulb gives around 1500-1700 lumens output, this is about 15 lumens per watt (15 lm/w). Things to keep in mind while shopping for LED bulbs always think about lumens output, not the watts.
