## Convert candela to lumens using this calculator – I (cd) to ϕ (lm)

Lumens and candela are units of measurement for lighting, but they measure different aspects of a lighting fixture. Lumens refers to the total amount of light that a lighting fixture emits, while candela refers to the amount of light emitted by a lighting fixture in a particular direction. In this article you will find the …
