2. 1 lm ÷ 0.079577472 = 12.5664 cd
Unit Information
Lumen (lm)
The lumen is the SI unit of luminous flux, measuring the total quantity of visible light emitted by a source.
1 lm = 1/4π cd (for uniform point source)1 lm = 0.079577472 cd (for uniform point source)
Candela (cd)
The candela is the SI unit of luminous intensity, measuring the power emitted by a light source in a particular direction.
1 cd = 4π lm (for uniform point source)1 cd = 12.56637061 lm (for uniform point source)
Common Applications
