"Yuav Lumens, tsis yog watts"
Nyob rau 1 Cuaj hlis 2010,European Uniontxoj cai lij choj tuaj mus rau hauv lub zog ua cov khoom siv teeb pom kev yuav tsum muaj cov lus piav qhia zoo li qub (LM), es tsis txhob siv hluav taws xob fais fab (w) .[12]
Yog tias koj lub qhov muag pom yog 1800lm,
| Yam | Ua tau zoo | Hwjchim | Tag nrho cov lumens |
| Zoo nkauj zoo | 70 lm / w | 25 W | 70 * {25=1750 lm |
| Swin zoo | 100 lm / w | 18 W | 100 * {18=1800 lm |
Dab tsi yog qhov sib txawv loj!
Yog tias koj xaiv cov khoom zoo, koj xav tau yuav 25w .
Yog tias koj xaiv Swin Zoo, 18W yog txaus .
Raws li peb txhua tus paub, lub zog qis dua yuav muaj kev txuag ntau dua thiab txo cov nqi hluav taws xob {}}
Yog li swin zoo nrog lumens siab yog qhov kev xaiv zoo .
