Umzi-mveliso wokukhanyisa waseTshayina wakhokelela ekukhanyeni kwe900 lumens

Zingaphi iiwatts ze900 lumens ezikhokelela ekukhanyeni?

Kuya kuba yi-9-10w. Ukuba ukuphuma kwe-lumen ye-LED yi-120lm / w, i-CRI 80

I-80% yokutshatyalaliswa kokukhanya, ukugqiba ukukhanya kwe-lumen kuya kuba yi-120×80%=96 lm/w

Ngokusekwe kwi-96lm/w, amandla okukhanya okukhokelwayo aya kuba yi-9-10w.
