Examples of illuminance
illuminance
The formal relationship of EV to luminance or illuminance has limitations.
From the en.wikipedia.org
When the moon is viewed at high altitude at tropical latitudes, the illuminance can reach 1 lux.
From the en.wikipedia.org
The SI unit of illuminance and luminous emittance, being the luminous power per area, is measured in Lux.
From the en.wikipedia.org
Exposure is a combination of the length of time and the illuminance at the photosensitive material.
From the en.wikipedia.org
It is commonly used in lighting applications that require minimal glare and uniform general illuminance levels.
From the en.wikipedia.org
Illuminance is measured with a flat receptor.
From the en.wikipedia.org
Bright sunlight provides illuminance of approximately 100,000 lux or lumens per square meter at the Earth's surface.
From the en.wikipedia.org
Exposure time is controlled in a camera by shutter speed and the illuminance by the lens aperture and the scene luminance.
From the en.wikipedia.org
Preference and motivation of laying hens to eat under different illuminances and the effect of illuminance on eating behaviour.

- The luminous flux incident on a unit area
- The measurement of light in lumens per square metre, the unit of which is the lux.
- The "density" of light (lumens/area) incident on a surface; i.e. the light level on a surface. Illuminance is measured in footcandles or lux.
- A photometric term that quantifies light incident on a surface or plane. Illuminance is commonly called light level. It is expressed as lumens per square foot (footcandles), or lumens per square meter (lux).
- Light arriving at a surface, expressed in lumens per unit area; 1 lumen per square foot equals 1 footcandle, while 1 lumen per square meter equals 1 lux.
- Is the quantity of light incident on (falling on) a surface area. In most environments there are many different surfaces in view, and they all receive different amounts of light; the average illuminance across all surfaces that are not in shadow is the light environment.
- Luminous flux incident on a surface per unit area. The SI of Illuminance is the Lux (lumen/m2), and the English unit of illuminance is the foot-candle (lumen/ft2). One lux = 0.0929 foot-candle, and reciprocally one foot-candle = 10.76 lux.
- Received luminous flux by unit area
