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.

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.
