Monga kufunikira kwaenergysavingsmtengolight ikupitilira kukula, kuyeza kwa ma lumens kumagwira ntchito yofunika kwambiri pakuwunika momwe njira zowunikira zimayendera bwino zachilengedwe. Poyerekeza kutulutsa kwa lumen kwa nyali zachikale za incandescent ndi njira zamakono za LED kapena CFL, mabungwe ndi ochita zisankho amatha kupanga zisankho zabwino kuti achepetse kugwiritsa ntchito mphamvu ndikuchepetsa kuwononga chilengedwe.
Monga tonse tikudziwira, pamene teknoloji ikupitilira kukula, ntchito zamalonda zidzapita patsogolo pang'onopang'ono. Komabe, chifukwa chakukula kwa intaneti, zinthu zimasakanizidwa, ndipo deta yabodza imapangitsa anthu kudabwa. Zonsezi zimapangitsa kuti zikhale zovuta kuti tisankhe zinthu zomwe zimakwaniritsa zosowa zathu. Makasitomala anga ambiri samamvetsetsa za lingaliro la lumens ndipo nthawi zonse amandifunsa ngati pali nyali zokhala ndi 10,000 lumens kapena kuposa 10,000 lumens. Kuphatikizana ndi zotsatirazi, kuti apange makasitomala kukhala ndi malingaliro omveka bwino a lumens.
Choyamba, lumens (yofotokozedwa ngati lm) imayimira kuchuluka kwa kuwala kowonekera komwe kumatulutsidwa ndi gwero la kuwala pa nthawi ya unit. M'mawu a anthu wamba, ndi za kuwala kwa nyali. Mosiyana ndi ma watts, omwe amayesa mphamvu zomwe zimagwiritsidwa ntchito ndi babu, ma lumens amawerengera makamaka kuwala kwa kuwala komwe kumapangidwa. Kusiyanitsa kumeneku ndikofunikira chifukwa kumapangitsa ogula kupanga zisankho zomveka posankha zinthu zowunikira, kuwonetsetsa kuti amasankha kuwala koyenera pazosowa zawo zenizeni.
Lingaliro la lumens limachokera ku photometry, sayansi yomwe imayang'ana kwambiri kuyeza kuwala kowoneka ndi maso a munthu. Kupyolera mu kuyesa mozama ndi kusanthula kwasayansi, ofufuza akhazikitsa njira zovomerezeka zodziwira molondola kutuluka kwa lumen kwa magwero osiyanasiyana a kuwala. Njira yasayansi iyi imatsimikizira kusasinthika ndi kudalirika kwa kuyeza kwa lumen, kupatsa ogula maziko odalirika oyerekeza zinthu zosiyanasiyana zowunikira.
Koma ma lumens amakhalanso ndi malire ogwiritsira ntchito. Ndipotu, pamsika wamakono, anthu nthawi zonse amawona tochi zolembedwa ndi 10,000 lumens kapena masauzande mazana a lumens. Koma zoona zake n’zakuti, n’zovuta kuti tochi zifike pamlingo uwu wa lumens, osasiya kuzisunga. Ngakhale pali milingo yapamwamba kwambiri, monga 10,000 lumens, kutalika kwake kumakhala pafupifupi sekondi imodzi, ndipo wogwiritsa ntchito akamatsegula, ndibwino kuti mutseke maso anu, chifukwa kuwala kumeneku kudzawononga maso anu. Ikafika sekondi imodzi, kuwala kwa uultrabkulondolafkuwalazidzachepa pang’onopang’ono m’kupita kwa nthaŵi, ndipo zina zidzacheperachepera kwambiri. Ngati tochi ikufuna kugwiritsidwa ntchito mosalekeza pa 10,000 lumens, kulongedza kwake kwakunja kudzawotcha, ndipo ndi kulolerana kwa khungu la munthu, sikutheka kuigwira ndikudzipweteka nokha. Ndipo luso lamakono lomwe liripo silingathe kukwaniritsa izi. Ngati muwalitsa 10,000 lumens papepala, pepalalo lidzayaka moto pakangopita mphindi zochepa.
Koma palinso zinthu zomwe zimafika makumi masauzande a lumens, mongahayipngongolewkapenalusiku,ndisolapngongolelamp, koma si onse amene angathe kufika kumeneko. Ngati mukufuna tochi kuti ikhale yowala mosalekeza, 500LM mpaka 1000LM ndi chisankho chabwino. Ndipo kuwala kwamtunduwu kwakhala kowala kwambiri. Mukamagwiritsa ntchito tochi, zotengera zake zakunja zimatentha pang'ono, koma thupi la munthu silingamve. Tochi imawotcha chifukwa chogwiritsa ntchito mosalekeza pakuwala kwambiri kumapangitsa kuti kutentha kuchuluke ndikupitilira kufalikira ku tochi. Kuchokera pamalingaliro othandiza, kumvetsetsa lumens ndikofunikira posankha njira yowunikira yomwe imakwaniritsa zofunikira zenizeni. Mwachitsanzo, posankha babu pabalaza, anthu atha kunena za kuyeza kwa lumen kuti aweruze mulingo wowala womwe umagwirizana bwino ndi malowo. Mofananamo, m'madera akunja monga minda kapena njira, lumen linanena bungwesolalndi kuscapelkuwalaakhoza kuganiziridwa mosamala kuti akwaniritse kuyatsa kofunidwa. Mwa kuphatikiza lingaliro la ma lumens popanga zisankho, anthu amatha kukulitsa zisankho zowunikira kuti zigwire bwino ntchito komanso kuwongolera mphamvu.
