Candela per Square Foot

cd/ft²

Definition

The Candela per Square Foot is an imperial unit of luminance, representing the luminous intensity per unit area using the square foot as the area unit. It is commonly used in countries that employ imperial measurement systems for lighting applications.

History/Origin

Developed as part of the imperial system of measurements, this unit provides a practical way to measure surface brightness in contexts where square feet are the standard area unit. It bridges the gap between metric and imperial systems in lighting applications.

Current Use

Used in lighting design and engineering in countries using imperial units, particularly in the United States. Common in architectural lighting, display specifications, and lighting calculations where square footage is the standard area measurement.

Lambert

L

Definition

The Lambert is a non-SI unit of luminance named after Johann Heinrich Lambert, equal to 3183.0988618379 candela per square meter. It is used in some specialized applications and provides an alternative way to express luminance values in certain technical contexts.

History/Origin

Named after the Swiss mathematician and physicist Johann Heinrich Lambert, this unit was developed as part of early photometric systems. It has historical significance in the development of photometry and is still used in some specialized applications and older technical literature.

Current Use

Used in some specialized photometric applications and historical contexts. Occasionally found in older technical specifications and certain branches of lighting science where traditional units are still preferred or required for compatibility with existing systems.
