Alternative symbols sometimes seen: W for luminous energy, P or F for luminous flux, and ρ for luminous efficacy of a source.

It is the ratio of luminous flux to power, measured in lumens per watt in the International System of Units (SI).

\theta _{\Sigma }}}} where Lv is the luminance (cd/m2), d2Φv is the luminous flux (lm) leaving the area dΣ in any direction contained inside the solid.

Luminous energy is the integrated luminous flux in a given period of time: Q v ∫ 0 T Φ v ( t ) d t {\displaystyle.

Luminous intensity should not be confused with another photometric unit, luminous flux, which is the total perceived power emitted in all directions.

Lumen can refer to: Lumen (unit), the SI unit of luminous flux Lumen (anatomy), the cavity or channel within a tubular structure Lumen (band), a Russian.

A phot (ph) is a photometric unit of illuminance, or luminous flux through an area.

The CU is the ratio of luminous flux from a luminaire incident.

It is based on the lumen, the SI unit of luminous flux, and the second, the SI base unit of time.

on light bulb packages, brightness means luminous flux, while in other contexts it means luminance.

The lumen (symbol: lm) is the SI derived unit of luminous flux, a measure of the total quantity of visible light emitted by a source per unit of time.
