Mukushomeka kwesimba kwemazuva ano, kushandiswa kwemagetsi kwave kutariswa kwakakosha kana vanhu vachitenga marambi nemarambi. Panyaya yekushandiswa kwemagetsi, magirobhu e LED anokunda matungsten ekare.
Kutanga, ma bulbs e LED anoshanda zvakanyanya kupfuura ekare tungsten bulbs. Magirobhu e LED anodarika 80% anowedzera simba-anoshanda kupfuura echinyakare incandescent bulbs uye 50% yakawanda-inoshanda simba kupfuura fluorescent bulbs, maererano neInternational Energy Agency. Izvi zvinoreva kuti magirobhu e LED anoshandisa simba rakaderera pane ekare tungsten bulbs pakupenya kwakafanana, izvo zvinogona kubatsira vanhu kuchengetedza mari pamagetsi nemagetsi mabhiri.
Chechipiri, mababu e LED anogara kwenguva refu. Ekare tungsten ma bulbs anongogara anenge 1,000 maawa chete, nepo ma LED bulbs anogona kugara anopfuura 20,000 maawa. Izvi zvinoreva kuti vanhu vanotsiva ma bulbs e LED zvishoma kazhinji pane ekare tungsten filament bulbs, kuderedza mutengo wekutenga uye kutsiva magirobhu.
Chekupedzisira, ma bulbs e LED ane zvirinani kuita kwezvakatipoteredza. Nepo magirobhu ekare etungsten anoshandisa zvinhu zvinokuvadza zvakaita semercury nemutobvu, magirobhu eLED haana iwo, zvichideredza kusvibiswa kwezvakatipoteredza.
Kupfupisa, ma bulbs e LED ari nani pane ekare tungsten bulbs maererano nekushandiswa kwesimba. Vanowedzera simba, vanogara kwenguva refu uye vane ushamwari hwezvakatipoteredza. Paunosarudza mwenje nemarambi, zvinokurudzirwa kusarudza ma bulbs e LED kuchengetedza simba uye mari yemagetsi, uye panguva imwechete kuti ubatsire kune zvakatipoteredza chikonzero.
