1. Nyali ya njanji ya LED imachokera ku LED.Gwero la kuwala kwa LED ndi gwero lozizira, lopanda ma radiation, palibe kuipitsidwa kwachitsulo cholemera, mtundu woyera, kuwala kwapamwamba kwambiri, kuwala kocheperako, kupulumutsa mphamvu komanso thanzi.Nyali zanjanji zagolide wamba za halogen zimakhazikitsidwa ndi nyali zagolide za halogen monga magwero owunikira.Mfundo yowala ya nyali za golide wa halide ndikuyankhira kuunika pambuyo popanga mpweya wa zinthu zachitsulo cholemera.Apo ayi, ikhoza kuipitsa chilengedwe (mercury element ndi heavy metal element, yomwe ndi yovulaza thanzi laumunthu.

2. Chimodzi mwazinthu zodziwika bwino za nyali yanjanji ya LED ndikupulumutsa mphamvu.Nyali zowongolera za LED ndi nyali zowongolera zagolide wamba zokhala ndi kuwala komweko.Zotsatira.

3. Moyo wa mtundu waukulu wopanga njanji ya LED kuwala ukhoza kufika maola osachepera 30,000, ndipo moyo wamba wamba golide halogen kalozera magetsi nthawi zambiri maola 8,000, zomwe zimasonyeza kuti moyo wautali.
