Monga kufunikira kwaemisalaskusungasmtengolkuwala Kupitilira kukula, kuyeza kwa ma lumens kumachita gawo lofunika kwambiri poyesa momwe magetsi amagwirira ntchito moyenera. Poyerekeza kutulutsa kwa ma lumen kwa nyali zachikhalidwe zoyatsira magetsi ndi njira zamakono za LED kapena CFL, mabungwe ndi opanga zisankho amatha kupanga zisankho zodziwikiratu kuti achepetse kugwiritsa ntchito mphamvu ndikuchepetsa kuwononga chilengedwe.
Monga tonse tikudziwa, pamene ukadaulo ukupitilira kukula, magwiridwe antchito azinthu azikula pang'onopang'ono. Komabe, chifukwa cha kukula kwa intaneti, zinthu zimasakanikirana, ndipo deta yabodza imapangitsa anthu kudabwa. Zonsezi zimapangitsa kuti zikhale zovuta kuti tisankhe zinthu zomwe zikugwirizana ndi zosowa zathu. Makasitomala anga ambiri sadziwa bwino lingaliro la ma lumens ndipo nthawi zonse amandifunsa ngati pali nyali zokhala ndi ma lumens 10,000 kapena kupitirira 10,000. Kuphatikiza ndi zotsatirazi, kuti makasitomala akhale ndi lingaliro lomveka bwino la ma lumens.
Choyamba, ma lumens (omwe amafotokozedwa ngati lm) amaimira kuchuluka konse kwa kuwala komwe kumawonekera komwe kumachokera ku gwero la kuwala pa nthawi imodzi. M'mawu a anthu wamba, izi zikunena za kuwala kwa nyali. Mosiyana ndi ma watts, omwe amayesa mphamvu yomwe babu limagwiritsa ntchito, ma lumens amawerengera makamaka kuwala kwa kuwala komwe kupangidwa. Kusiyana kumeneku ndikofunikira chifukwa kumalola ogula kupanga zisankho zomveka bwino posankha zinthu zowunikira, ndikuwonetsetsa kuti asankha kuwala koyenera zosowa zawo.
Lingaliro la ma lumens limachokera pa photometry, sayansi yomwe imayang'ana kwambiri pa kuyeza kuwala kooneka komwe maso a munthu amakuona. Kudzera mu kuyesa ndi kusanthula kwasayansi kokhwima, ofufuza akhazikitsa njira zokhazikika kuti adziwe molondola kutulutsa kwa magwero osiyanasiyana a kuwala. Njira yasayansi iyi imatsimikizira kukhazikika ndi kudalirika kwa muyeso wa ma lumen, ndikupatsa ogula maziko odalirika oyerekeza zinthu zosiyanasiyana zowunikira.
Koma ma lumens alinso ndi malire enaake ogwiritsira ntchito. Ndipotu, pamsika wamakono, anthu nthawi zonse amawona ma tochi olembedwa ndi ma lumens 10,000 kapena ngakhale ma lumens mazana ambiri. Koma kwenikweni, n'zovuta kuti ma tochi afike pamlingo uwu wa ma lumens, osanenapo za kuusunga. Ngakhale pali milingo yayikulu, monga ma lumens 10,000, nthawi yake yayitali ndi pafupifupi sekondi imodzi, ndipo wogwiritsa ntchito akayatsa switch, ndibwino kutseka maso anu, chifukwa kuwala kumeneku kudzawononga maso anu. Kukafika sekondi imodzi, kuwala kwa uLtrabkumanjafkuwala kwa disopang'onopang'ono idzachepa pang'onopang'ono pakapita nthawi, ndipo zina zidzachepa kwambiri. Ngati tochi ikufuna kugwiritsidwa ntchito mosalekeza pa ma lumens 10,000, phukusi lake lakunja lidzatentha, ndipo chifukwa cha kupirira kwa khungu la munthu, sizingatheke kuigwira ndipo idzakuvulazani nokha. Ndipo ukadaulo womwe ulipo pano sungakwaniritse izi. Ngati muwalitsa ma lumens 10,000 papepala, pepalalo lidzayaka moto patatha mphindi zochepa.
Koma palinso zinthu zomwe zimafika pa ma lumens zikwi makumi ambiri, mongahighpngongolewntchitolma lightsndisdzuwapngongolelamp, koma si onse omwe angafike pamenepo. Ngati mukufuna kuti tochi isunge kuwala kwina nthawi zonse, 500LM mpaka 1000LM ndi chisankho chabwino. Ndipo kuwala komwe kuli muyeso uwu kumakhala kowala kale. Mukamagwiritsa ntchito tochi, phukusi lake lakunja limatentha pang'ono, koma thupi la munthu silingathe kulimva. Tochi imatentha chifukwa kugwiritsa ntchito kwake kosalekeza kuwala kwakukulu kumabweretsa kutentha kusonkhanitsa ndikupitiliza kufalikira ku tochi. Kuchokera pamalingaliro othandiza, kumvetsetsa ma lumens ndikofunikira posankha yankho lowunikira lomwe likukwaniritsa zofunikira zinazake. Mwachitsanzo, posankha babu la chipinda chochezera, anthu amatha kugwiritsa ntchito lumen rating kuti aweruze mulingo wowala womwe umagwirizana bwino ndi malowo. Mofananamo, m'malo akunja monga minda kapena njira, kutulutsa kwa lumen kwasdzuwalandscapelkuyatsa magetsiakhoza kuganiziridwa mosamala kuti akwaniritse kuunikira komwe kukufunika. Mwa kuphatikiza lingaliro la ma lumens mu njira yopanga zisankho, anthu amatha kusintha njira zowunikira kuti zigwire bwino ntchito komanso kuti mphamvu zigwiritsidwe ntchito moyenera.
