Description

Footcandle (fc): Imperial Unit of Illuminance

The footcandle is a non-SI unit of illuminance used primarily in the United States. It is defined as the illuminance on a one-square-foot surface from a uniform source of light equivalent to one lumen. One footcandle equals approximately 10.764 lux. Despite the global shift towards SI units, the footcandle remains prevalent in certain industries and applications.

Understanding footcandles is important for professionals working in lighting design, architecture, and photography within regions that use imperial measurements. It allows for the assessment and specification of lighting requirements, ensuring that spaces are adequately illuminated according to established standards and practices.

Candela (cd): The SI Unit of Luminous Intensity

The candela is the SI base unit for measuring luminous intensity, representing the power emitted by a light source in a particular direction. Defined by the International System of Units, one candela corresponds to the luminous intensity of a source emitting monochromatic radiation at a frequency of 540 × 1012 hertz with a radiant intensity of 1/683 watt per steradian. This unit is fundamental in photometry, providing a standardized measure for the brightness of light sources as perceived by the human eye.

In practical applications, the candela is essential for designing lighting systems, ensuring consistent illumination levels in various environments such as workplaces, public spaces, and homes. Understanding and utilizing the candela allows engineers and designers to create lighting solutions that meet specific intensity requirements, enhancing visual comfort and energy efficiency.
