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 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.
