Hefner CandleHef
Target UnitThe Hefner candle is a unit of luminous intensity, specifically defined as the light produced by a standard Hefner candle, which emits a luminous intensity of approximately 1.0 candela. The Hefner candle is based on the illumination produced by a specific type of wax candle, which serves as a reference standard for measuring luminous intensity. This unit is particularly important in the fields of lighting design and photometry, as it provides a consistent measure for comparing the light output of various sources. The Hefner candle is not commonly used today but played a significant role in the historical development of photometric measurement standards.
Current Use
While the Hefner candle is not widely used in contemporary scientific and industrial applications, its historical significance remains relevant in understanding the evolution of luminous intensity measurement. Today, the candela is the preferred unit for measuring light intensity, and industries such as photography, theater production, and architectural lighting rely on precise measurements of luminous intensity. Countries such as Germany, Italy, and the United States, which have a rich history in lighting technology, reference the Hefner candle when discussing the historical context of light measurement standards. Although modern devices and technologies have overshadowed the Hefner candle, its legacy lives on in the principles of photometry and lighting design.
Fun Fact
The Hefner candle was one of the first attempts to standardize light measurement before the introduction of the candela.

The Hefner candle is not commonly used today but played a significant role in the historical development of photometric measurement standards.
History & Origin
The Hefner candle originated in the late 19th century, named after the German physicist Friedrich Hefner, who contributed significantly to the standardization of light measurement. Hefner's work aimed to establish a reliable basis for measuring light output from candles, which were the primary light sources of that era. By defining a standard candle, Hefner provided a method for ensuring consistency across various lighting applications, which was crucial for industries relying on accurate light measurements. The need for a standardized unit arose as the demand for artificial lighting increased, and the variability of candles made comparisons difficult.
Etymology: The term 'Hefner' derives from the name of its inventor, Friedrich Hefner, reflecting his contributions to the field of photometry.
