Hefner Candle

hefner candle

Definition

The Hefner Candle is a unit of luminous intensity based on the light output of a Hefner lamp burning amyl acetate. It was developed as a standardized reference for luminous intensity measurements and was widely used in German-speaking countries before the adoption of international standards.

History/Origin

Named after Friedrich von Hefner-Alteneck, who developed this standard in 1884. It was based on the light output of a specific lamp burning amyl acetate and provided a reproducible standard for photometric measurements in Germany and other German-speaking regions.

Current Use

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

Bougie Decimal

bougie decimal

Definition

The Bougie Decimal is a unit of luminous intensity that is numerically equivalent to one international candle. It represents a decimal-based approach to luminous intensity measurement and provides a convenient reference point for calculations in photometric applications.

History/Origin

Developed as part of the decimal system of measurements, providing a standardized unit for luminous intensity that aligns with metric principles. It was designed to simplify calculations and provide a consistent reference for light measurement across different applications.

Current Use

Used in various photometric applications where decimal-based calculations are preferred. It provides a convenient reference for scientific measurements and is often used in educational contexts to explain luminous intensity concepts.
