Millilambert

Definition

The Millilambert is a unit of luminance equal to one-thousandth of a lambert (0.001 lambert). It provides a more convenient way to express moderate luminance values using the lambert system, making calculations and specifications more manageable.

History/Origin

This unit was developed as a practical alternative to the full lambert unit when dealing with moderate luminance values. The milli- prefix makes it easier to work with typical luminance levels without using very large or very small numbers in the lambert system.

Current Use

Used in specialized photometric applications where the lambert system is preferred. Common in certain technical contexts and applications where traditional photometric units are still used or required for compatibility with existing measurement systems.

Lumen per Square Foot Steradian

lm/(ft²·sr)

Definition

The Lumen per Square Foot Steradian is an imperial unit of luminance that shows the relationship between luminous flux, area, and solid angle using square feet. It is equivalent to 10.7639104167 candela per square meter.

History/Origin

This unit was developed for use in countries employing imperial measurements, providing a way to express luminance in terms of square feet while maintaining the relationship to luminous flux and solid angle. It bridges metric and imperial systems in lighting applications.

Current Use

Used in lighting design and engineering in countries using imperial units, particularly in architectural lighting and display specifications. Common in applications where square footage is the standard area measurement and precise luminance control is required.
