What is illuminance?

Illuminance is a measure of how much light reaches a given surface. It is usually measured in lux or footcandles, but can also be expressed in lumens per square meter. Illuminance can be used to determine the amount of light needed for a task, as well as the best placement of lighting fixtures.

How to convert between units of illuminance?

There are many different units of illuminance, but the three most common are lux, lumen, and footcandles. To convert between these units, you need to know a few basic facts about each unit.

Lux is the SI unit of illuminance and is equal to one lumen per square meter. Lumen is the unit of luminous flux, the amount of light emitted by a source. Footcandles are an imperial unit of illuminance and are equal to one lumen per square foot.

To convert from lux to lumen, simply multiply the number of lux by the area in square meters.For example, if you have an illuminance of 100 lux over an area of ​​10 square meters, then the luminous flux is 1000 lumens.

To convert from lumens to footcandles, divide the number of lumens by the area in square feet. So if you have a lumen output of 1000 lumens over an area of ​​100 square feet, then the illuminance would be 10 foot candles.
