The Wikipedia has the following information about this codepoint:
The lumen (symbol: lm) is the unit of luminous flux, a measure of the perceived power of visible light emitted by a source, in the International System of Units (SI). Luminous flux differs from power (radiant flux) in that radiant flux includes all electromagnetic waves emitted, while luminous flux is weighted according to a model (a "luminosity function") of the human eye's sensitivity to various wavelengths; this weighting is standardized by the CIE and ISO. One lux is one lumen per square metre; similarly, one foot-candle is one lumen per square foot.
The lumen is defined in relation to the candela as
- 1 lm = 1 cd·sr.
A full sphere has a solid angle of 4π steradians, so a light source that uniformly radiates one candela in all directions has a total luminous flux of
- 1 cd × 4π sr = 4π cd⋅sr = 4π lm ≈ 12.57 lm.
