About These Units
Watt at 555nm (W@555nm)
Watts at 555nm represents the peak luminous efficacy of radiation: exactly 683 lumens per watt at 555nm wavelength (green-yellow light where human eye is most sensitive). This fundamental constant links radiometric (watts) to photometric (lumens) measurements.
Hefnerkerze (HK)
The Hefnerkerze (HK) is a historical German unit based on the Hefner lamp flame (amyl acetate). One Hefnerkerze ≈ 0.903 international candelas. Mean Spherical HK × 4π ≈ lumens. Used in Germany until mid-20th century; now obsolete.
