FOOT CANDLE Meaning and
Definition
-
A foot-candle, abbreviated as fc, is a unit of illuminance used to measure the amount of light falling onto a surface. It is defined as the illuminance produced by one lumen of light evenly distributed over an area of one square foot.
In simpler terms, a foot-candle measures the intensity of light that reaches a particular point on a surface per unit area. This unit is commonly used in architectural, engineering, and facility management fields to determine appropriate lighting levels for various applications.
To put it into perspective, one foot-candle is equivalent to the amount of light emitted by a standard candle, illuminating a surface positioned one foot away. Another way to understand this unit is to imagine a lux-to-foot-candle ratio, as one foot-candle is approximately equal to 10.764 lux.
Foot-candles are often used in lighting design to ensure that light levels are adequate for specific tasks or activities. For example, the recommended foot-candle levels for general office spaces are typically between 20 and 50 fc, while specialized environments such as surgical rooms may require considerably higher levels.
Understanding foot-candles allows professionals to assess and evaluate the quality and quantity of lighting in a space, ensuring optimal visibility, safety, and comfort. By measuring foot-candles, designers and engineers can achieve the desired lighting levels for a variety of applications, promoting productivity, efficiency, and overall well-being.
