Njengemfuno yeeuburhalarhumesavingsumthilbusuku iyaqhubeka ikhula, ukulinganiswa kwe-lumens kudlala indima ephambili ekuvavanyeni ukusebenza kwezisombululo zokukhanyisa ezihambelana nokusingqongileyo. Ngokuthelekisa ukukhutshwa kwe-lumen yezibane zendabuko ze-incandescent kunye ne-LED yanamhlanje okanye ezinye iindlela ze-CFL, imibutho kunye nabenzi bezigqibo banokwenza izigqibo ezinolwazi ukunciphisa ukusetyenziswa kwamandla kunye nokunciphisa impembelelo yokusingqongileyo.
Njengoko sonke siyazi, njengoko itekhnoloji iqhubeka nokuphuhliswa, ukusebenza kwemveliso kuya kuphucula ngokuthe ngcembe. Nangona kunjalo, ngophuhliso olukhulayo lwe-Intanethi, iimveliso ziyaxutywa, kwaye idatha yobuxoki yenza abantu bamangaliswe. Konke oku kwenza kube nzima kuthi ukukhetha iimveliso ezihlangabezana neemfuno zethu. Uninzi lwabathengi bam abacacanga malunga nombono we-lumens kwaye bahlala bendibuza ukuba kukho izibane ezine-lumens eziyi-10,000 okanye ngaphezulu kwe-10,000 yelumens. Ukudibanisa nesi siphumo, ukwenzela ukuba abathengi babe nombono ocacileyo we-lumens.
Okokuqala, i-lumens (echazwa njenge-lm) imele inani elipheleleyo lokukhanya okubonakalayo okukhutshwa ngumthombo wokukhanya ngexesha leyunithi. Ngokwemigaqo yabantu abaqhelekileyo, imalunga nokuqaqamba kwesibane. Ngokungafaniyo neewatts, ezilinganisa amandla asetyenziswa yibhalbhu, iilumens zilinganisa ngokuthe ngqo ukuqaqamba kokukhanya okuvelisiweyo. Lo mahluko ubalulekile kuba uvumela abathengi ukuba benze izigqibo ezicacileyo xa bekhetha iimveliso zokukhanyisa, baqinisekise ukuba bakhetha ukukhanya okufanelekileyo kwiimfuno zabo ezithile.
Umbono we-lumens usekwe kwiphotometry, isayensi egxile ekulinganiseni ukukhanya okubonakalayo okubonwa liliso lomntu. Ngovavanyo olungqongqo lwenzululwazi kunye nohlalutyo, abaphandi baye baseka iindlela ezisemgangathweni zokuqinisekisa ngokuchanekileyo ukuphuma kwe-lumen yemithombo eyahlukeneyo yokukhanya. Le ndlela yenzululwazi iqinisekisa ukuhambelana kunye nokuthembeka komlinganiselo we-lumen, ukubonelela abathengi ngesiseko esithembekileyo sokuthelekisa iimveliso zokukhanyisa ezahlukeneyo.
Kodwa i-lumens nayo inemida ethile yokusetyenziswa. Enyanisweni, kwiimarike zanamhlanje, abantu bahlala bebona izibane eziphawulwe nge-lumens eyi-10,000 okanye amakhulu amawaka e-lumens. Kodwa eneneni, kunzima ukuba iithotshi zifikelele kweli nqanaba le-lumens, masingasathethi ke ngokuyigcina. Nangona kukho amanqanaba aphezulu, afana ne-lumens eyi-10,000, ubude bayo obuphezulu malunga nomzuzwana omnye, kwaye xa umsebenzisi evula umtshini, kungcono ukuvala amehlo akho, kuba oku kukhanya kuya kuwonakalisa amehlo akho. Xa ifikelela kwisekondi enye, ukuqaqamba kwe uokokugqibelabkunenefisibaneziya kuncipha ngokuthe ngcembe ekuhambeni kwexesha, kwaye ezinye ziya kuncipha kakhulu. Ukuba i-flashlight ifuna ukusetyenziswa ngokuqhubekayo kwi-lumens ye-10,000, ukupakishwa kwayo kwangaphandle kuya kutshisa, kunye nokunyamezela kwesikhumba somntu, akunakwenzeka ukuba uyibambe kwaye uya kuzilimaza. Kwaye iteknoloji ekhoyo ngoku ayikwazi ukuhlangabezana nale mfuneko. Ukuba ukhanyisa i-10,000 lumens yokukhanya ephepheni, iphepha liya kubamba umlilo ngokuthe ngqo emva kwemizuzu embalwa.
Kodwa kukwakho izinto ezifikelela kumashumi amawaka elumens, njengehighpunetyalawoklamabala, kwayesolarpunetyalalamp, kodwa asingabo bonke abanokufikelela oko. Ukuba ufuna isibane sigcine isixa esithile sokukhanya ngokuqhubekayo, i-500LM ukuya ku-1000LM lukhetho olulungileyo ngokwenene. Kwaye ukukhanya kolu luhlu sele kukhanya kakhulu. Xa usebenzisa isibane, ukupakishwa kwayo kwangaphandle kuya kufudumeza kancinane, kodwa umzimba womntu awuva nzima. Isibane siyatshisa ngenxa yokuba ukusetyenziswa kwayo ngokuqhubekayo kokukhanya okuphezulu kuya kubangela ukuba ubushushu buqokelele kwaye buqhubeke busasazeka kwisibane. Ukusuka kumbono osebenzayo, ukuqonda i-lumens kubalulekile ekukhetheni isisombululo sokukhanyisa esihlangabezana neemfuno ezithile. Umzekelo, xa ukhetha ibhalbhu yegumbi lokuhlala, abantu banokubhekisa kwi-lumen rating ukugweba inqanaba lokuqaqamba elifanele indawo. Ngokufanayo, kwiindawo zangaphandle ezifana negadi okanye iindlela, ukuphuma kwe-lumensolarlkunye nokubukekalukukhanyainokuqwalaselwa ngononophelo ukufezekisa ukukhanya okufunayo. Ngokubandakanya ingqikelelo ye-lumens kwinkqubo yokwenza izigqibo, abantu banokuphucula ukhetho lokukhanyisa ukusebenza kunye nokusebenza kakuhle kwamandla.
