{0}Amalambu e-pressure mercury aphezulu ayigesi-amalambu akhiphayo akhipha ukukhanya ngokusekelwe ekuphumeni komhwamuko we-mercury. Isimiso sabo sokusebenza siwukuthi indawo kagesi-ephakeme kakhulu ijabulisa umhwamuko we-mercury ukuze ukhiqize ukukhanya kwe-ultraviolet, okube sekuguqulelwa ekukhanyeni okubonakalayo ngama-phosphor ngaphakathi kweshubhu lesibani. Kusukela ekuthuthukisweni kwawo maphakathi nekhulu lama-20, lobu buchwepheshe bubambe isikhundla esibalulekile ekukhanyisweni kwezimboni, ezentengiselwano, nangaphandle ngenxa yezindawo zabo ezihlukile zokubona kanye nokusebenza kahle kwamandla okuphezulu.
Izici zobuchwepheshe eziyinhloko-zezibani ze-pressure mercury eziphezulu ukusebenza kahle kwazo kokukhanya nempilo ende. Uma kuqhathaniswa nezibani zendabuko ze-incandescent, zingafinyelela ama-lumens angu-50-60 nge-watt ngayinye, okunciphisa kakhulu ukusetshenziswa kwamandla. Ngaphezu kwalokho, ngenxa yokuthi umhwamuko we-mercury uphuma ngaphansi kwengcindezi ephezulu, kwakheka i-plasma ezinzile ngaphakathi kweshubhu lesibani, okuholela ekuphileni kwesibani ngokuvamile esingaphezu kwamahora angu-10,000. Lezi zibani zilungele izinhlelo zokusebenza ezidinga ukusebenza okuqhubekayo kwesikhathi eside, njengokukhanyisa umgwaqo, izindawo zokusebenzela zasefekthri, nezinkundla zemidlalo.
Ngokuya ngezici ze-spectral, ukukhanya okukhiphayo{0}}izibani ze-pressure mercury ngokuyinhloko kuluhlaza okwesibhakabhaka-okuluhlaza okotshani, nenani elincane lokukhanya kwe-ultraviolet. Inkomba yabo yokunikeza umbala (CRI) ngokuvamile iphansi (cishe 40-}60), okusho ukuthi abakwazi ukukhiqiza kabusha imibala yezinto. Nokho, lesi sici sibanika inzuzo ezinhlelweni ezidinga ukukhanya okuphezulu kodwa ukunemba kombala okungafuneki kangako, njengamarobhothi noma ukukhanya kwangaphandle. Ngaphezu kwalokho, amalambu e-mercury anengcindezi ephezulu anesikhathi eside sokuqalisa, ngokuvamile imizuzu emi-4-8, ukuze athole ukukhanya okuzinzile, futhi ukuqala kabusha kudinga ukulinda ukuthi isibani siphole. Lesi sici sinciphisa ukuguquguquka kwazo kwezinye izinhlelo zokusebenza.
Ubuchwepheshe besimanje buthuthukise nakakhulu ukusebenza-kwamalambu e-pressure mercury ngokuthuthukiswa kokumbozwa kwe-phosphor kanye ne-electrode design. Isibonelo, ukungezwa kwe-phosphor yomhlaba engavamile kuthuthukisa ukunikezwa kombala, kuyilapho ukusetshenziswa kwama-ballasts kagesi kuthuthukisa isivinini sokuqalisa kanye nokusebenza kahle kokuguqulwa kwamandla. Naphezu kokukhula ngokushesha kobuchwepheshe be-LED eminyakeni yamuva,{3}}amalambu e-pressure mercury aphezulu ahlala engenakushintshwa kwezinye izinhlelo zokusebenza ngenxa yobuchwepheshe bawo obuvuthiwe kanye nezindleko eziphansi. Ngokuzayo, njengoba imithetho yezemvelo iqinisa imikhawulo ekusetshenzisweni kwe-mercury, amalambu e-mercury aphezulu{5}angase athathelwe indawo kancane kancane kufakwe ezinye izindlela ezivumelana nemvelo. Kodwa-ke, izinzuzo zabo zobuchwepheshe zisanikeza inani elibalulekile lokubhekisela kumaphrojekthi okukhanyisa.
