Njengoko imfuno yeei-nergysukuphumelelasitreetlukukhanya iyaqhubeka ikhula, ukulinganiswa kwee-lumens kudlala indima ebalulekileyo ekuvavanyeni ukusebenza kakuhle kwezisombululo zokukhanyisa ezinobuhlobo nokusingqongileyo. Ngokuthelekisa imveliso ye-lumen yezibane zemveli ze-incandescent kunye neyezinye iindlela zanamhlanje ze-LED okanye ze-CFL, imibutho kunye nabenzi bezigqibo banokwenza izigqibo ezinolwazi lokunciphisa ukusetyenziswa kwamandla kunye nokunciphisa impembelelo yokusingqongileyo.
Njengoko sonke sisazi, njengoko iteknoloji iqhubeka nophuhliso, ukusebenza kwemveliso kuya kuphucuka kancinci kancinci. Nangona kunjalo, ngophuhliso olukhulayo lwe-Intanethi, iimveliso ziyaxutywa, kwaye idatha engeyonyani yenza abantu bamangaliswe. Konke oku kwenza kube nzima ngakumbi kuthi ukukhetha iimveliso ezihlangabezana neemfuno zethu. Uninzi lwabathengi bam alucacanga malunga nengcamango yee-lumens kwaye bahlala bendibuza ukuba kukho izibane ezinee-lumens ezili-10,000 okanye ngaphezulu kwe-lumens ezili-10,000. Xa zidityaniswe nale miphumo, ukuze abathengi babe nengcamango ecacileyo yee-lumens.
Okokuqala, ii-lumens (ezichazwa njenge-lm) zimele isixa siphela sokukhanya okubonakalayo okukhutshwa ngumthombo wokukhanya ngexesha ngalinye. Ngokwendlela eqhelekileyo, kubhekiselele ekukhanyeni kwesibane. Ngokungafaniyo nee-watts, ezilinganisa amandla asetyenziswa yibhalbhu, ii-lumens zilinganisa ngokukodwa ukukhanya kokukhanya okuvelisiweyo. Lo mahluko ubalulekile kuba uvumela abathengi ukuba benze izigqibo ezicacileyo xa bekhetha iimveliso zokukhanyisa, beqinisekisa ukuba bakhetha ukukhanya okufanelekileyo kwiimfuno zabo ezithile.
Ingcamango ye-lumens isekelwe kwi-photometry, isayensi egxile ekulinganiseni ukukhanya okubonakalayo okubonwa liliso lomntu. Ngovavanyo oluqinileyo lwesayensi kunye nohlalutyo, abaphandi baseke iindlela ezisemgangathweni zokuchonga ngokuchanekileyo imveliso ye-lumen yemithombo eyahlukeneyo yokukhanya. Le ndlela yesayensi iqinisekisa ukuhambelana kunye nokuthembeka kokulinganiswa kwe-lumen, inika abathengi isiseko esithembekileyo sokuthelekisa iimveliso zokukhanya ezahlukeneyo.
Kodwa ii-lumens nazo zinemida ethile yokusetyenziswa. Enyanisweni, kwimarike yanamhlanje, abantu bahlala bebona ii-flashlights eziphawulwe ngee-lumens ezili-10,000 okanye amakhulu amawaka ee-lumens. Kodwa enyanisweni, kunzima ukuba ii-flashlights zifikelele kweli nqanaba lee-lumens, ingasathethwa ke ngokuzigcina. Nokuba kukho amanqanaba aphezulu kangaka, njengee-lumens ezili-10,000, ubude bazo obuphezulu bumalunga nomzuzwana omnye, kwaye xa umsebenzisi evula iswitshi, kungcono ukuvala amehlo akho, kuba olu kukhanya kuya konakalisa amehlo akho. Xa lufikelela kumzuzwana omnye, ukukhanya kwe uI-ltrabkunenefisibane selaphuiza kuncipha kancinci kancinci ngokuhamba kwexesha, kwaye ezinye ziya kuncipha kakhulu. Ukuba ithotshi ifuna ukusetyenziswa rhoqo kwi-10,000 lumens, ukupakishwa kwayo kwangaphandle kuya kufudumala, kwaye ngokunyamezela kolusu lomntu, akunakwenzeka ukuba uyibambe kwaye uya kuzenzakalisa. Kwaye ubuchwepheshe obukhoyo ngoku abunakuyifezekisa le mfuneko. Ukuba ukhanyisa i-10,000 lumens yokukhanya ephepheni, iphepha liya kutsha ngqo emva kwemizuzu embalwa.
Kodwa kukwakho nezinto ezifikelela kumashumi amawaka ee-lumens, ezifanahighpityalawumsebenzilii-lightskunyesilangapityalali-amp, kodwa asingabo bonke abanokufikelela kuloo nto. Ukuba ufuna ithotshi igcine ubungakanani obuthile bokukhanya rhoqo, ukusuka kwi-500LM ukuya kwi-1000LM lukhetho olufanelekileyo. Kwaye ukukhanya okukule luhlu sele kuqaqambile kakhulu. Xa usebenzisa ithotshi, ukupakisha kwayo kwangaphandle kuya kufudumala kancinci, kodwa umzimba womntu awukwazi ukuyiva. Ithotshi iyatshisa kuba ukusetyenziswa kwayo okuqhubekayo kokukhanya okuphezulu kuya kubangela ukuba ubushushu buqokeleleke kwaye buqhubeke busasazeka kwithotshi. Ngokwembono esebenzayo, ukuqonda ii-lumens kubalulekile ekukhetheni isisombululo sokukhanyisa esihlangabezana neemfuno ezithile. Umzekelo, xa ukhetha ibhalbhu yegumbi lokuhlala, abantu banokubhekisa kumlinganiselo we-lumen ukugweba inqanaba lokukhanya elifanele indawo. Ngokufanayo, kwiindawo zangaphandle ezifana neegadi okanye iindlela, imveliso ye-lumen yesilangali-andscapelukukhanyisaingaqwalaselwa ngononophelo ukuze kufezekiswe ukukhanya okufunekayo. Ngokufaka ingcamango ye-lumens kwinkqubo yokwenza izigqibo, abantu banokwenza ukhetho lokukhanyisa lube ngcono ukuze kusebenze kakuhle kwaye kusetyenziswe kakuhle amandla.
