What is difference between lux and lumens?

The difference between the units lumen and lux is that the lux takes into account the area over which the luminous flux is spread.

How bright is 1000 lumens?

The Brightness of a 1000 Lumen Flashlight A 1000 lumen flashlight is quite bright and, depending on the lens or reflector design, powerful enough to reach a distance of 200 meters or more. This type of flashlight allows you to see objects from a far distance.

How bright is 400 lumen?

A lumen measures the amount of light that comes from a bulb. It refers to a light bulb’s brightness, intensity of light and visible light emitted. A standard 40-watt (40W) bulb is equal to 400+ lumens.

How bright is 800 lumens?

That takes lumens. Lumens measure brightness. A standard 60-watt incandescent bulb, for example, produces about 800 lumens of light.

How many lumens is 1 lux?

Lumens: The total output of visible light from a light source is measured in lumens. Typically, the more lumens a light fixture provides, the brighter it is. One lux is equal to one lumen per square meter (lux = lumens/m2).
