Godiya ga sakonka kuma don Allah a gafarta jinkirin amsa. Mun sami wannan tambayar da yawa. Yawancin lokaci nakan amsa da tambaya ta tawa:

Shin kuna adana kuɗi idan kun sayi samfurin da baya yin abin da yakamata yayi?

Muna rage farashi mai rahusa bias lights wanda farashinsa yayi daidai da na Lumadoodle, yayin da yake bayar da daidaito na matakin ƙwararru, garanti mai tsawo da ƙarin zaɓuɓɓukan haɗi. 

Don haka, idan kuna neman yin kwatancen da ya dace, zan kwatanta Lumadoodle da sabon sabo LX1 Bias Lighting daga wannan ƙungiyar MediaLight.

Akwai abubuwa da yawa da za a iya samar da cikakken haske na son zuciya fiye da ɗaukar ƙaramin CRI (75 Ra kawai) na zango na LED, "cire bututun filastik da sanya kwali a baya," kamar yadda Lumadoodle ke so ku yi imani.

Idan ba kwa son yin mummunan tasiri ga hoton TV, to akwai ƙa'idodi don CRI (Fitar da Launin Launin Launi), chromaticity da rarraba wutar lantarki ta yanayi mai haske wanda ya kamata a bi.
