Ntau wattage tsis txhais hais tias ntau brightness

Cia peb dispel ib qho lus dab neeg tsis tu ncua. Qhov kev pom zoo tshaj plaws yog qhov ci ntsa iab nce nrog tus naj npawb ntawm watts. Tab sis qhov tseeb yog qhov ci ci tsis muaj dab tsi cuam tshuam nrog watts. Tus naj npawb ntawm cov hluav taws xob siv los ntawm lub teeb ci yog ntsuas hauv watts. Cov lumen, uas sawv cev rau qhov ntsuas ntawm qhov ci, yuav tsum tau kuaj xyuas.

Piav txog Lumens.

Ib lub teeb ci tshwj xeeb qhov ci ci yog ntsuas hauv lumens. Lumens yog cov lus luv luv rau qhov ci los yog kev siv ntawm koj lub teeb. Feem ntau cov tib neeg feem ntau confuse noj thiab lumen. Txawm li cas los xij, lumens yog txhua yam hais txog qhov ci thaum watts cuam tshuam nrog kev siv hluav taws xob.

Lumens yog units ntawm brightness.

Lumen yog ib chav tsev siv los piav qhia txog qhov ci ci ntawm qhov chaw tshwj xeeb. Ntau qhov ci ci yog sib npaug rau ntau lumens ib watt.

Los ntawm kev hloov mus rau LED teeb, koj yuav tau txais:

- Brightest ntau lawm ntawm lub teeb

- Ze li ntawm 60–70 feem pua ​​​​txo cov nqi hluav taws xob

- Piv rau CFL qhov muag teev, lub teeb LED muaj kev nyab xeeb dua vim nws tsis tso cov mercury txaus ntshai. (Thaum muaj tshuaj lom mercury los ntawm tib neeg lub cev, nws tuaj yeem ua rau muaj kev phom sij rau ntau yam kev noj qab haus huv uas tuaj yeem ua rau muaj kev phom sij rau cov menyuam yaus thiab cov poj niam cev xeeb tub)

12w Round Led Vaj Huam Sib Luag Teeb

Feature:

● Qhov no dawb, 12W round recessed LED vaj huam sib luag teeb yog tsim los ntawm 60 SMD2835 chips.
● Vim tias tag nrho cov cuab yeej ua los ntawm txhuas, qhov zoo tshaj plaws ua kom txias thiab ua kom lub neej ntev.
● Cov teeb pom kev tsis ncaj yog muab los ntawm lub mat plexi npog, thiab cov leds tsis pom.
● Lub khw teeb pom kev zoo feem ntau siv cov dawb 12W round recessed LED vaj huam sib luag teeb nrog 166mm txoj kab uas hla.
