Ainihin fari da ake gani (misali, fari mai sanyi, fari tsaka-tsaki) ya dogara da ainihin wurin. Tsarin binning (S1-S4) yana haɗa LED tare da haɗin gwiwa da suka dace don tabbatar da daidaiton launi.

Q: Shin ana buƙatar magudanar zafi don wannan LED?
A> Saboda ƙarancin raguwar wutar lantarki (72mW), yawanci ba a buƙatar magudanar zafi na musamman ba. Duk da haka, kyawawan ayyukan shimfidar PCB, kamar amfani da isasshen tagulla don kushin zafi, suna da mahimmanci don fitar da zafi daga haɗin LED, musamman a cikin yanayin zafin yanayi mai girma ko lokacin da aka tuƙi shi a matsakaicin halin yanzu.
