Lumen (lm)
| CCTV glossary (глоссарий терминов по видеонаблюдению) |
The unit of luminous flux. it is equal to the flux through a unit solid angle (steradian) from a uniform point source of one candela or to the flux on a unit surface of which all points are at a unit distance from a uniform point source of one candela.
