Illumination, английский
- Освещение; облучение (цели)
- Lighting minus craft. also, someone else`s setup.
- The amount or intensity of light striking an object.
- The luminous flux density incident on a surface, i.e., the luminous flux per unit area; usually expressed in lumens per square foot or footcandles, and lumens per square meter or lux.
- Act of illuminating or state of being illuminated. see also illuminate. compare illuminance.2,6
Illuminance, английский
- The amount of light, which falls onto a given surface area. measured in lux.
- The light density, or luminous flux per unit area, incident on a surface.
- The density of luminous power, also called “illumination.” one lumen of luminous flux, uniformly incident on 1 square foot of area, produces an illuminance of 1 footcandle; in si units, one lumen of luminous flux, uniformly incident on 1 square meter of area, produces an illuminance of 1 lux.
- Освещ
- Intensity of radiant energy (density of luminous flux) on a surface, in the visible light spectrum. illuminance is measured in lux.
- Intensity of visible light per unit area (density of luminous flux) on a surface. illuminance is measured in lumens per square meter (lm/m2) or lux. compare luminance.
- Intensity of radiant energy in the visible light spectrum. illuminance is measured in footcandles or lux.

Type of program (drama, documentary, newscast, interview, etc.).
Foo/foobar, английский
A sort of on-line algebraic place holder, for example if you want to know when another site is run by a for-profit company, look for an address in the form of foo@foobar.com.
