Tej zaum koj yuav xav paub ntau npaum li cas wattage koj xav tau kom tau txais qhov tseeb ci yog tias koj tab tom yuav khoom rau lub teeb tshiab. Tshwj xeeb, koj tuaj yeem xav paub txog tus naj npawb ntawm watts xav tau los muab 3,000 lumens ntawm lub teeb. Cia peb tshuaj xyuas cov ncauj lus no thiab nws qhov cuam tshuam rau koj cov teeb pom kev zoo kom ntxaws ntxiv.
Cia peb pib los ntawm kev txhais cov lumens. Tag nrho cov teeb pom kev zoo uas tsim los ntawm lub teeb yog ntsuas hauv lumens. Lub teeb yuav tshwm ci dua qhov ntau lumens nws tsim. Conversely, wattage yog ib qho kev ntsuas ntawm lub hwj chim npaum li cas lub teeb siv. Feem ntau, lub teeb yuav tsum muaj zog ntau dua nws cov wattage.
Tom qab ntawd, pes tsawg watts xav tau los tsim 30,000 lumens ntawm lub teeb? Hom teeb uas koj siv yuav txiav txim qhov kev daws teeb meem. Feem ntau ua tau ib ncig ntawm 15 lumens ib wat, incandescent qhov muag teev tau phased tawm nyob rau hauv ntau lub teb chaws vim lawv inefficiency. Qhov no qhia tau hais tias ib lub teeb ci incandescent nrog wattage ntawm kwv yees li 20 (300 lumens / 15 lumens ib watt) yuav tsum tsim kom muaj 300 lumens ntawm lub teeb.
Txawm li cas los xij, wattage yuav tsum tau ua kom muaj 30o lumens yuav qis dua yog tias koj siv lub teeb pom kev zoo dua, xws li LED lossis CFL qhov muag teev. Piv txwv li, LED teeb yuav muab txog li 100 lumens ib watt, txhais tau tias a300 lumen LED teebtsuas yog yuav tsum tau kwv yees li ntawm 3 watts ntawm lub zog (300 lumens / 100 lumens ib watt). CFL qhov muag teev, uas kuj muaj txiaj ntsig zoo, feem ntau tawm ntawm 60 thiab 80 lumens ib watt, yog li ntawd 30-lumen CFL noob yuav xav tau kwv yees li 4 mus rau 5 watts ntawm lub zog.
Txhawm rau muab nws luv luv, cov teeb pom kev zoo uas koj siv los txiav txim siab yuav tsum muaj pes tsawg watts los tsim peb caug lumens ntawm lub teeb. Yuav kom tsim tau 300 lumens, ib lub teeb ci incandescent yuav tsum kwv yees li 20 watts. Txawm li cas los xij, koj tsuas yog xav tau ib feem me me ntawm qhov ntawd - kwv yees li peb mus rau tsib watts - yog tias koj siv lub teeb ci LED lossis CFL. Thaum muas lub teeb, nco ntsoov saib cov lumens thiab watts kom paub tseeb tias koj tau txais lub zog- teeb pom kev zoo uas ua tau raws li koj xav tau.
