1, e khanyang: ha li-lumens li le holimo, leseli le khanya haholoanyane!

Ka ntle, hangata "khanya" e bohlokoa haholo. Mohlala, haeba u le tseleng ea bosiu kapa u hlahloba lehaha, khanya ha ea lekana e ka khoptjoa, ea oa, kapa ea fosa letšoao la bohlokoa; "mabone" a tla u etsa "tlokotsi". Haeba u hloka ho khanya, joale u lokela ho ela hloko li-lumens.

(1) Tekanyo ea khanya ho tsoa ho li-lumens

Bophelo, hangata re re leseli "le khanyang kapa che", ha e le hantle, le bolela phallo e khanyang. Yuniti ea phallo e khanyang ke lumen, e bonts'ang bokhoni ba khanya ba mohloli oa leseli. Haeba u batla ho reka mabone a khanyang, re lokela ho ela hloko li-lumens tsa paramethara ena. Khanya e phahameng e u lumella ho bona tikoloho e ka pel'a hau ka ho hlaka.

(2) Ha boleng ba lumen bo le boholo, leseli le khanya haholoanyane.

Bakeng samabone a kantle le mabone a mabone, ho na le kamano e ntle pakeng tsa li-lumens le khanya: ha boleng ba lumen bo le boholo, phallo ea khanya e ba kholoanyane, matla a khanya a mohloli oa leseli a ba maholo. Mohlala,Lebone la hlooho la lumen la 1000 e khanya ho feta Lebone la hlooho la 300 lumen.

(3) Khetho ea khanya

Ha theko ea sehlahisoa e phahame, khanya ea sona e lokela ho kopanngoa le tšebeliso ea sona ea sebaka seo. Li-lumens tse 100 li lekana le khanya ea likerese tse 8, mesebetsi ea mantlha ea ho hloa lithaba kantle ho kampo e lekana ho khetha li-lumens tse 100 ho isa ho tse 200; lihlahisoa tsa mabone a tšohanyetso a manyane boholo ba tsona li ka har'a li-lumens tse 50 kapa ho feta, empa li ka boela tsa khotsofatsa litlhoko tsa mabone.

Haeba o nka karolo lipapaling tsa kantle o na le litlhoko tse phahameng tsa mabone, o ka nahana ka lihlahisoa tsa lumens tse 200 ~ 500. Haeba ho na le litlhoko tse phahameng, tse kang ho tsamaea ka lebelo haholo (ho matha bosiu ho pholletsa le naha), kapa tlhoko ea ho bonesa sebaka se seholo, o ka nahana ka lihlahisoa tsa lumens tse 500 ~ 1000.

Litlhoko tsa litsebi, tse kang ho batla pholoso, u ka nahana ka ho fetangLi-lumens tse 1000 lebone la hlooho. Khanya ha e bolele hole, ka linako tse ling u hloka ho batla le ho shebella, ka sebele u tšepa hore leseli le hole hanyane, joale u hloka paramethara e 'ngoe e boletsoeng ka tlase.
