Ib qho teeb meem tseem ceeb tshaj plaws ntawm HID ncej teeb yog tias lawv xav tau kev saib xyuas zoo heev. Lub teeb muaj lub neej ntev ntawm 15,000-25,000 teev, uas qhia tias cov kws tshaj lij hluav taws xob yuav tsum tau hloov lawv ntau zaus - cov txheej txheem uas tuaj yeem ua haujlwm hnyav thiab siv sijhawm, xav txog yuav ua li cas siab lub teeb feem ntau yog.
Feem ntau, thaum HID teeb tau hloov pauv cov ballasts yuav tsum tau hloov, uas ntxiv rau tag nrho cov nqi kho.
HIDs kuj muaj qhov sib piv siab heev ntawm lumen devaluation nrog rau ntau ntawm lawv cov lumens ua ntej lawv ncav cuag lawv lub neej-ntev.
Raws li qhov tseeb, los ntawm lub sijhawm lawv ncav cuag tsib caug feem pua ntawm lawv lub neej, lawv yuav poob ib nrab ntawm lawv cov lumen. Lawv cov txheej txheem deterioration kuj tsis yog ib qho yooj yim thaum lawv pib hloov xim thaum lawv mus txog qhov kawg ntawm lawv lub neej.
Cov kws tshaj lij hluav taws xob ib txwm xav tau hloov qhov muag teev kom sai li sai tau thaum lawv qhov kev ua tau zoo qis dua li ntau qhov chaw sab nraud nrog lub teeb mast siab xav tau lub teeb pom kev zoo tshaj plaws.
LEDs muaj lub neej ntev (50,{1}} txog 100,000 teev), tuav 70 feem pua ntawm lawv cov lumens rau lawv lub neej tag nrho, tsis txhob siv cov ballasts, thiab tsis hloov xim raws li lawv muaj hnub nyoog. Lub teeb feem ntau tsis muaj kev saib xyuas, tsuas yog kev saib xyuas uas yuav tsum tau ua yog ntxuav cov khoom siv.
