illuminance's Usage Examples:

In photometry, illuminance is the total luminous flux incident on a surface, per unit area.

The lux (symbol: lx) is the SI derived unit of illuminance, measuring luminous flux per unit area.

The Kruithof curve describes a region of illuminance levels and color temperatures that are often viewed as comfortable or pleasing to an observer.

luminous power is concentrated into a smaller area, meaning that the illuminance is higher at the image.

luminous/photometric exposure E is the image-plane illuminance t is the exposure time ("shutter speed") The illuminance E is controlled by the f-number but also.

daylight received in an internal space can be analyzed by measuring illuminance on a grid or undertaking a daylight factor calculation.

candle; abbreviated fc, lm/ft2, or sometimes ft-c) is a non-SI unit of illuminance or light intensity.

task lighting refers to increasing illuminance to better accomplish a specific activity.

However, the illuminance level is not the only factor governing.

A phot (ph) is a photometric unit of illuminance, or luminous flux through an area.

slightly revised definition of illuminance, measurements with a hemispherical receptor indicate “effective scene illuminance.

foot-lamberts is equal to the incident illuminance in foot-candles.

For real diffuse reflectors, the ratio of luminance to illuminance in these units is roughly equal.
