Linked from

The 12 pages that link to Luminous efficacy, each with the reason it gives.

• IlluminanceRelated: It links the eye-weighted light used in illuminance to physical radiant power.

• Incandescent light bulbRelated: This measure captures the incandescent bulb’s central tradeoff: simple light production but low efficiency.

• Luminous fluxRelated: It quantifies how much visible output a given optical power produces.

• Photopic visionRelated: Its standard photopic weighting reflects human brightness sensitivity across wavelengths.

• RadiometryRelated: It quantifies how photometric output relates to radiometric power.

• Luminous intensityRelated: It links visually weighted light output to physical radiant power.

• CandelaRelated: The candela’s definition uses a fixed efficacy for monochromatic radiation at 540 terahertz.

• Solid-state lightingRelated: It compares how effectively electrical input becomes visually weighted light.

• White LEDRelated: It quantifies how efficiently a white LED converts electrical input into visually weighted light.

• Gas-discharge lampRelated: It compares how efficiently different discharge lamps convert electricity into visible light.

• Gas mantleRelated: Mantles extracted more visible light from fuel than a bare gas flame.

• Electric lightRelated: It compares how efficiently different electric sources turn power into visible light.
