The unit of illumination when the foot is taken as the unit of length. It is the illumination on a surface one square foot in area on which there is a uniformly distributed flux of one lumen or the illumination produced on a surface all points of which are at a distance of one foot from a point source of one candela.
A unit of measurement indicating how much illumination is reaching a surface.
A unit of illuminates, incident light, or illumination equal to 1 lumen per square foot. This is the illuminants provided by a light source of one candle at a distance of 1 foot, hence the name.
a measurement of the illumination of one candle falling on an object one foot away, while wattage is the amount of light emanating from a source
Measurement of light falling on an object. Abbreviated fc.
Abbreviated as fc, the foot-candle is a measurement of the amount of light falling upon an object at any given moment (illumination), called such as it refers to the amount of light falling on a square foot area located one foot away from a candle.
A unit of measurement of the intensity of light. 1 FC = 10 lux
The Foot-candle is the measurement of light output in candela per square foot. The Foot-candle is used frequently to quantify the amount of light present in a given area. In the B&H Web Site, many of the lights will list the photometric data next to the light. The unit the light is measured by is in foot-candles. The photometric data will enable you to compare the performance of the products you may be interested in. The Foot-candle is a standard reference unit used to measure the illuminance on a surface that is everywhere one foot from a uniform point source of light of one candle and equal to one lumen per square foot.
The amount of light generated by 1 candle 1 foot away.
the amount of light falling on one square foot from a distance one foot away.
A measure of light useful in determining intensity of light for growing orchids; the illumination produced by a candle at a distance of one foot.
A unit of illuminance or illumination equal to one lumen per square foot. This is the illuminance provided by a light source of one candle at a distance of one foot.
It is the light intensity (illumination) of a surface one foot distant from a source of one candela. It is equal to one lumen per square foot. (1FC = 1 lm ft2). The foot-candle is the unit used to measure incident light.
The amount of light reflected by a surface one foot from a lighted candle. Metric equivalent is one lumen or one foot candle of light over a one square foot surface.
The unit of illumination equal to one lumen per square foot. Formative Evaluation An evaluation performed at a late development stage, used to revise and improve an training program before launch.
A unit of illuminance, or how much total light is reach onto a surface, such as a wall or table. One lumen falling on one square foot of surface produces illumination of one foot-candle. One foot-candle is equal to 1 lumen per square foot.
The light intensity (illumination) of a surface one foot distant from a source of one candle. It is equal to one lumen per square foot. (1 FC = 1 lm/sq. ft.). The foot-candle is the unit used to measure incident light.
A foot-candle is equivalent to one lumen per square foot (where a lumen is a measure of the luminous flux, or quantity of light). A wax candle flame has a luminous intensity (or equivalently, candlepower) of approximately one candela. If you hold the candle one foot away from a surface, the illuminance of the surface at this distance due to the light from the candle will be approximately one foot-candle. It will be 1/4 fc at two feet, 1/9 fc at three feet, and so on in accordance with the inverse square law for point light sources.
The unit of illumination on a surface one square foot in area on which is uniformly distributed a flux of one lumen. Equal to 10.76 Lux (ASAE EP344.2 Dec99)
A unit of illumination equal to the intensity of one candle at a distance of one foot. Foot-candles are usually used as a measure of light received.
This is the common measurement of luminance (level of light) used in the United States. One foot-candle is one lumen on one square-foot of a surface. (See also Lumen and Lux).
A foot-candle (sometimes footcandle; abbreviated fc, lm/ft², or sometimes ft-c) is a non-SI unit of illuminance or light intensity widely used in photography, film, television, and the lighting industry.
