Unit of light intensity, measured in lumens per square foot. The brightness of one candle at a distance of one foot. Approximately 10.7639 lux.Lumen (lm) Unit of light flow or luminous flux. The output of artificial lights can be measured in lumens.Lux...
Lux, unit of illumination (see luminous intensity) in the International System of Units (SI). One lux (Latin for “light”) is the amount of illumination provided when one lumen is evenly distributed over an area of one square metre. This is also equival
< Back to All Light Measurement Resources Q. What is the difference between foot-candles (fc) and foot-lamberts (fL) or lux and candela/m² (cd/m²)? A. Fc and lux are illuminance measurements (photometric flux per unit area) typically taken using a cosine corrector or a detector ...
The inverse square law defines the relationship between irradiance from a point source and the distance to the measurement surface. It states that the intensity per unit area varies in inverse proportion to the square of the distance between the source and surface. ...

The metric system illumination unit is lux (lx) and is equal to a meter candle. It means, illuminance on a surface is one candela source per meter. Foot candle (lumen per square foot) is a non-SI unit of illumination. 1 foot candle (fc) is equal to 10.76 lux. ...
