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.

Pentane Candle (10 Candle Power)
pentane candle (10 candle power)
Definition
The Pentane Candle (10 Candle Power) is a unit of luminous intensity equal to ten times the standard pentane candle. It represents a higher intensity light source used for specific photometric applications requiring greater luminous output than the standard reference.
History/Origin
Developed as a higher-intensity reference standard for photometric measurements where the standard pentane candle was insufficient. It provided a reproducible standard for measuring brighter light sources and was used in specialized photometric applications.
Current Use
Primarily of historical interest, though may still be referenced in older photometric literature or specialized applications. It has been largely replaced by the international candle standard and its multiples for modern applications.
