KnowraLuminous fluxLinked fromLinked fromThe 14 pages that link to Luminous flux, each with the reason it gives.All 14Related 6Narrower topic 2Compared with 6Stellar luminosityCompared with: Unlike luminosity, flux depends on distance from the star.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.RadiometryCompared with: It parallels radiant flux but weights each wavelength by visual sensitivity.BrightnessCompared with: Total emitted light is a source property and does not by itself specify how bright a surface appears.CandlepowerCompared with: Unlike candlepower, it describes total output rather than intensity in one direction.
