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.

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.
