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 Second (lm·s): Measuring Luminous Energy

The lumen second, also known as the talbot, is a unit of luminous energy, representing the total amount of light emitted over a period of time. It is calculated by multiplying luminous flux (in lumens) by time (in seconds). This unit is useful in applications where the duration of light exposure is significant, such as in photography, lighting design, and vision science.

By quantifying the cumulative light output, the lumen second allows for the assessment of energy usage, exposure levels, and the effectiveness of lighting systems over time. This information is crucial for optimizing performance, ensuring safety, and enhancing energy efficiency in various contexts.
