Carcel Unit

carcel unit

Definition

The Carcel Unit is a unit of luminous intensity based on the light output of a Carcel lamp burning colza oil. It was developed as a standardized reference for luminous intensity measurements and was widely used in France before the adoption of international standards.

History/Origin

Developed in France as a standardized reference for luminous intensity based on the light output of a specific lamp burning colza oil. It was named after the Carcel lamp and provided a reproducible standard for photometric measurements in French-speaking regions.

Current Use

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

Candle (International)

Definition

The Candle (International) is the SI base unit of luminous intensity, defined as the luminous intensity in a given direction of a source that emits monochromatic radiation of frequency 540×10¹² hertz and has a radiant intensity in that direction of 1/683 watt per steradian.

History/Origin

The international candle was established in 1948 as part of the International System of Units (SI). It replaced earlier candle standards and provides a precise, reproducible definition based on fundamental physical constants, ensuring consistency in light measurement worldwide.

Current Use

Widely used as the standard unit for measuring luminous intensity in scientific research, lighting design, and photometric applications. It is essential for calibrating light sources, designing lighting systems, and ensuring accurate light measurements in various industries.
