Tsim koj li 18W LED lub teeb ci los tawm tsam lub caij ntuj no nyuaj. Lub teeb ci no nthuav dav thiab dimmable siv PWM. Yog tias koj muaj lub teeb timer, koj tuaj yeem siv nws ua lwm txoj hauv kev rau lub tswb tswb.

Kauj Ruam 2: Kuv Yuav Tsum Muaj pes tsawg LEDs?

10,000, lux feem ntau siv rau lub teeb dawb. Qib qis qis yog qhov muaj txiaj ntsig, txawm hais tias koj xav tau sijhawm ntev dua. Rau lub teeb ntsuab, 350 lux yog sib npaug rau 10, 000 lux ntawm lub teeb dawb. Ib lux yog sib npaug rau 1 lumen ib square meter. Nco ntsoov tias diffusers tseem thaiv lub teeb. Lux meter yuav pab tau.
