Candela to Lumens Converter
Note: Assumes isotropic source (4π steradians).
Definition
The candela (cd) is the SI unit of luminous intensity, measuring light emitted in a specific direction, equal to 1 lumen per steradian for an isotropic source. A lumen (lm) is the SI unit of luminous flux, representing total visible light output, where 1 cd emits 4π lumens (≈12.57 lm) over a full sphere.
History
The candela evolved from the candlepower standard in the 19th century, formalized in 1948 and refined in 1979 by the SI system based on a monochromatic light source. The lumen, also SI-defined, traces back to early photometry in the 1800s, standardized alongside candela to measure lighting efficiency.
