Kev tsis
Kev sib piv luminous efficiency: incandescent teeb nyhuv yog 10-15lm, halogen tungsten lub teeb nyhuv yog 12-24 lumens/watt, fluorescent teeb yog 50-90 lumens / watt, sodium teeb yog 90-140 lumens / watt, thiab feem ntau ntawm kev siv hluav taws xob ua cua sov poob.
LED teeb pom kev zoo: nws tuaj yeem tso tawm 50-200 lumens / watt, thiab muaj qhov zoo monochromaticity thiab nqaim spectrum. Nws tuaj yeem ncaj qha emit xim pom lub teeb yam tsis tau lim.
