Description

Footlambert (fL): Imperial Unit of Luminance

The footlambert is a non-SI unit of luminance used primarily in the United States, particularly in the cinema and projection industries. One footlambert equals approximately 3.426 candelas per square meter. This unit measures the brightness of images projected onto screens, ensuring optimal viewing conditions in theaters and auditoriums.

Professionals in the film and display sectors rely on footlambert measurements to calibrate projection systems and maintain consistent image quality. Understanding and applying this unit is essential for achieving the desired visual experience in various viewing environments.

Phot (ph): CGS Unit of Illuminance

The phot is a unit of illuminance in the centimeter-gram-second (CGS) system, where one phot equals 10,000 lux. Although it is not commonly used in modern applications, the phot provides a historical reference point for high-intensity lighting measurements, particularly in scientific research and specialized fields.

While the SI unit lux has largely supplanted the phot, familiarity with this unit can be beneficial when interpreting older scientific literature or working within specific contexts where CGS units are still in use. Recognizing the conversion between phot and lux ensures accurate understanding and communication of illuminance values.
