Candle (Pentane)

candle (pentane)

Definition

The Candle (Pentane) is a unit of luminous intensity based on the light output of a pentane lamp burning at a specific rate. It was used as a standard reference for luminous intensity measurements before the adoption of more precise international standards.

History/Origin

Developed as a standardized reference for luminous intensity based on the light output of a pentane lamp burning at a controlled rate. It provided a reproducible standard for photometric measurements before the establishment of the international candle standard.

Current Use

Primarily of historical interest, though may still be referenced in older photometric literature or standards. It has been largely replaced by the international candle standard for modern applications and scientific measurements.

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.
