About These Units
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.
Candela Steradian (cd·sr)
A candela steradian (cd·sr) is the defining relationship for lumens: 1 lumen = 1 candela × 1 steradian. Shows how luminous flux relates to luminous intensity (candelas) and solid angle (steradians). A sphere has 4π ≈ 12.57 steradians total solid angle.
