Lumen per Square Meter Steradian

lm/(m²·sr)

Definition

The Lumen per Square Meter Steradian is a unit of luminance that explicitly shows the relationship between luminous flux, area, and solid angle. It is dimensionally equivalent to candela per square meter and provides insight into the geometric aspects of light measurement.

History/Origin

This unit was developed to emphasize the relationship between luminous flux, surface area, and solid angle in luminance measurements. It provides a more detailed understanding of how light is distributed and measured in three-dimensional space.

Current Use

Used in advanced photometry and lighting calculations where the relationship between flux, area, and solid angle is important. Common in research applications and detailed lighting analysis where understanding the geometric aspects of light distribution is crucial.

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.
