About Microcandelas
The microcandela (µcd) equals 10⁻⁶ cd. LED indicators in standby or low-power mode: many SMD status LEDs operate at 1-100 µcd when current-limited to 10-100 µA. Also the typical sensitivity threshold of modern photomultiplier tube assemblies. 1 µcd = 10⁻⁶ cd.
About Hefnerkerzen
The Hefnerkerze (HK) equals 0.920 cd (DIN 5031 conventional value). The German photometric standard unit from 1884 to 1942, defined by the luminous intensity of a Hefner lamp burning amyl acetate. Used as the official German standard before the adoption of the international candela. 1 HK = 0.920 cd.
