Svjetlosna učinkovitost ili luminacijska efektnost (oznaka η) je fotometrijska fizikalna veličina kojom se opisuje učinak određenih frekvencija elektromagnetskih valova na ljudski osjet vida; omjer je svjetlosnog toka Фs i toka zračenja Ф, to jest:
Najveća je svjetlosna učinkovitost (683 lm/W) žutozelene svjetlosti, valne duljine 555 nm. Mjerna jedinica svjetlosne učinkovitosti jest lumen po vatu (lm/W). [1]
Stupanj iskorištenja raznih izvora svjetlosti
Stupanj iskorištenja izvora svjetlosti, za umjetnu rasvjetu, je bezdimenzionalni odnos između svjetlosnog toka (sim. Φ; jed. lm) koje emitira svjetlo i ulazne električne snage (sim. P; jed. W), koje to svjetlo troši.
