Mwenje we LED unosiyana kubva kune incandescent uye fluorescent munzira dzakawanda.Kana yakagadzirwa zvakanaka, mwenje we LED unoshanda zvakanyanya, unochinja-chinja, uye unogara kwenguva refu.
Ma LED ndiwo "directional" light sources, zvinoreva kuti anobudisa chiedza mune imwe nzira, kusiyana ne incandescent neCFL, iyo inobudisa chiedza nekupisa kumativi ose.Izvi zvinoreva kuti ma LED anokwanisa kushandisa chiedza uye simba zvakanyanya muhuwandu hwekushanda.Nekudaro, zvinoreva zvakare kuti huinjiniya hwakaoma hunodiwa kugadzira mwenje we LED unopenya mwenje munzira dzese.
Akajairika ma LED mavara anosanganisira amber, tsvuku, girini, uye bhuruu.Kuti ibudise chiedza chichena, ma LED akasiyana-siyana anosanganiswa kana kuvharwa ne phosphor zvinhu zvinoshandura ruvara rwechiedza kune rinozivikanwa "chena" chiedza chinoshandiswa mudzimba.Phosphor chinhu chine yellowish chinovhara mamwe ma LED.Ma LED ane mavara anoshandiswa zvakanyanya semarambi echiratidzo uye mwenje wechiratidzo, sebhatani remagetsi pakombuta.
MuCFL, magetsi anoyerera pakati pema electrode pamagumo echubhu ine magasi.Izvi zvinogadzira ultraviolet (UV) chiedza uye kupisa.Iyo UV mwenje inoshandurwa kuita mwenje unooneka painorova phosphor coating mukati me bulb.
Incandescent bulbs inogadzira chiedza uchishandisa magetsi kupisa simbi filament kusvika yave "chena" kupisa kana kunzi incandesce.Nekuda kweizvozvo, incandescent bulbs inoburitsa 90% yesimba ravo sekupisa.
