Kutheni iiBhalbhu zokukhanya ezibubungqina bokudubula ziqhekeka ngokulula

1. Ngaba igesi yebhalbhu okanye i-incandescent? Iibhalbhu ze-incandescent azikho ixesha elide lokuphila, ngakumbi kwiindawo ezirhabaxa ze-oilfield-proof-proof light lights, apho bahlala besilela khona. Nangona kunjalo, ubude bobomi bee-bulbs bunokwandiswa ukuba i-metal halide okanye izibane ze-sodium ezinoxinzelelo oluphezulu zisetyenziswa. Ingakumbi, iiglowubhu ezivela ePhilips naseOsram zihlala ixesha elide, ngokubanzi ngaphezu kweminyaka emibini.

2. Ngaphaya kohlobo kunye nebhrendi yebhalbhu, ulwakhiwo loyilo ngokubanzi lubalulekile. Abanye abavelisi bavelisa izibane ezikumgangatho ophantsi wobungqina bokudubula ngaphandle kweenkqubo ezifanelekileyo zokulahla ubushushu, ekhokelela kwiibhalbhu ezivuthayo ngokukhawuleza.
