footcandle
A unit of illumination equal to 1 lumen ft-2 Full sunlight with zenith sun produces an illuminance of the order of 10,000 fc on a horizontal surface Full moonlight provides an illuminance of about 0 02 fc Adequate illumination for steady reading is about 10 fc Close machine work is required about 30 to 40 fc
footcandle
The unit of measure for the density of light as it reaches a surface One footcandle is equal to one lumen per square foot Measured footcandles are sensitive to the distance from the source to the surface of measure (inverse square law) and the angle at which the light reaches the surface (cosine law)
footcandle
-Standard unit of measure for illumination on a surface The Average footcandle level on a square surface is equal to the lumens striking the surface, divided by the area of the surface
footcandle
The illuminance on a surface 1 ft2 in area on which there is a uniformly distributed flux of 1 lm, or the illuminance produced on a surface all points of which are at a distance of 1 ft from a directionally uniform point source of 1 cd (For SI users, one footcandle equals 10 76 lux )
footcandle
A standard measurement of illuminance, representing the amount of illuminance on a surface one foot square on which there is a uniformly distributed flux of one lumen
footcandle
A measurement of light level It is equivalent to the light intensity made by one candle at a distance of one foot
