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.

Lumen (lm): Measuring Luminous Flux

The lumen is the SI unit of luminous flux, quantifying the total amount of visible light emitted by a source per unit of time. One lumen is defined as the luminous flux emitted within a unit solid angle (one steradian) by a point source with a uniform luminous intensity of one candela. This unit is crucial for evaluating the overall brightness of light sources, such as bulbs and LEDs.

In practical terms, lumens provide a direct measure of a light source's output, enabling consumers and professionals to assess and compare the brightness of different lighting products. Higher lumen values indicate greater light output, which is essential for applications requiring specific illumination levels, from residential lighting to commercial and industrial settings.
