Lumen per Steradian
lm/sr
Definition
The Lumen per Steradian is a unit of luminous intensity that is dimensionally equivalent to the candela. It represents the luminous flux emitted in a given direction per unit solid angle, providing an alternative way to express luminous intensity in terms of luminous flux.
History/Origin
Derived from the fundamental definition of the candela, which is one lumen per steradian. It provides an alternative perspective on luminous intensity by emphasizing the relationship between luminous flux and solid angle in photometric measurements.
Current Use
Widely used in theoretical photometry and in calculations where the luminous flux aspect of light is emphasized. It provides a direct link to the fundamental definitions of light measurement and is interchangeable with the candela in most practical applications.

Candle (UK)
c (UK)
Definition
The Candle (UK) is a historical unit of luminous intensity used in the United Kingdom, equivalent to approximately 1.0417 international candles. It was based on the light output of a specific type of candle used in British photometric standards before metrication.
History/Origin
Established in the United Kingdom as part of their imperial measurement system before the adoption of international standards. It was based on the light output of specific British-made candles and was used for photometric measurements in the UK and Commonwealth countries.
Current Use
Primarily of historical interest, though may still be encountered in older British technical specifications or historical documents. It has been largely replaced by the international candle standard for modern applications and scientific measurements.
