Unit Information

Lumen (lm)

Definition: The SI unit of luminous flux.

History: From Latin "lumen" meaning light.

Current Use: Used for measuring light output of bulbs and fixtures.

Candela (cd)

Definition: The SI base unit of luminous intensity, representing luminous flux per unit solid angle (lumens per steradian).

History: Adopted as the SI base unit for luminous intensity; modern definition ties to monochromatic radiation of frequency 540 THz.

Current Use: Fundamental unit to specify brightness (luminous intensity) of light sources.

Kilolumen (klm)

Definition: A unit of luminous flux equal to 1,000 lumens.

History: A multiple of the lumen used for high‑output light sources.

Current Use: Common in specifications for projectors and architectural lighting.
