Linked from

The 14 pages that link to Luminous flux, each with the reason it gives.

• LuminanceNarrower topic: It totals visible light across directions, while luminance specifies light in a direction and across an area.

• Stellar luminosityCompared with: Unlike luminosity, flux depends on distance from the star.

• IlluminanceRelated: Illuminance divides incident luminous flux by the receiving surface's area.

• Radiant fluxCompared with: Unlike radiant flux, it weights optical power by human visual sensitivity.

• IrradianceCompared with: It weights radiation by vision, whereas irradiance measures physical radiant power.

• Luminous efficacyRelated: It is the numerator of luminous efficacy, measured in lumens.

• RadiometryCompared with: It parallels radiant flux but weights each wavelength by visual sensitivity.

• Theatrical lightingRelated: It distinguishes a fixture's overall light output from the brightness of a lit surface.

• Luminous intensityRelated: Its distribution across directions determines luminous intensity.

• BrightnessCompared with: Total emitted light is a source property and does not by itself specify how bright a surface appears.

• CandelaNarrower topic: It is the photometric quantity from which luminous intensity is derived by direction.

• Stage lightingRelated: It describes a source's total visible output before beam direction is considered.

• CandlepowerCompared with: Unlike candlepower, it describes total output rather than intensity in one direction.

• FlashlightRelated: It describes the visible-light output of a flashlight independently of beam direction.
