Difference Between Lux and Lumen

Lux and lumens, both units indicate a light intensity. ... “Lumen indicates the amount of light emitted by a light source, while lux gives the illuminance on a certain surface, for example a desk or workstation.” Lumen. The lumen (symbol: lm) is the unit for luminous flux.

How many lumens are in a 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).

Can you convert Lux to lumens?

Lux and lumen units represent different quantities, so you can't convert lux to lumens.

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 many lumens is a 10000 Lux light?

These lamps are rated for 5,000 to 10,000 lux (or 10,000 Lumens per square foot), with the majority of lamps favoring 10,000 for good measure. This is roughly equivalent to the intensity of sunlight during the afternoon.

How many Lux is too bright?

Earlier it was common with light levels in the range 100 - 300 lux for normal activities. Today the light level is more common in the range 500 - 1000 lux - depending on activity. For precision and detailed works, the light level may even approach 1500 - 2000 lux.

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 do you calculate Lux?

One lux is equal to one lumen per square metre: 1 lx = 1 lm/m² = 1 cd·sr/m². A flux of 1000 lumens, spread uniformly over an area of 1 square metre, lights up that square metre with an illuminance of 1000 lux. However, the same 1000 lumens spread out over 10 square metres produces a dimmer illuminance of only 100 lux.
