Magetsi a LED ndi chipangizo cha semiconductor chomwe chitha kutulutsidwa kapena kugwiritsidwa ntchito ngati gwero la kuwala.Magetsi a LED amatha kuyatsa mwa kutembenuza mphamvu yamagetsi kukhala mphamvu yowunikira, yomwe ili ndi ubwino wopulumutsa mphamvu ndi kuteteza chilengedwe, kuwala kwakukulu, moyo wautali, ndi kusankha mitundu yambiri.

-Kupulumutsa mphamvu ndi kuteteza chilengedwe: Nyali za LED ndizopulumutsa mphamvu kuposa nyali zachikhalidwe.Kugwiritsa ntchito mphamvu kwa kuwala pa tile ndi kotsika kwambiri kuposa nyali za incandescent, ndipo nthawi yomweyo, mpweya wa CO2 umachepetsedwa.
-Kuwala kwakukulu: Nyali za LED zimakhala ndi zowala kwambiri, zomwe zimatha kupanga mphamvu zambiri zowunikira kuti zikwaniritse zosowa zosiyanasiyana zowunikira.
-Utali wautali: Magetsi a LED amakhala ndi moyo wautali ndipo amatha kufika maola masauzande ambiri, omwe ndiatali kuposa nyali zachikhalidwe.
-Sankhani mitundu: Magetsi a LED amatha kusankha mitundu yosiyanasiyana ndi mawonekedwe ngati pakufunika kuti akwaniritse zokongoletsa ndi kukongoletsa chilengedwe.
-Kukonza kosavuta: Nyali za LED ndizosavuta kuzisamalira ndikuzisintha, chifukwa zimatha kusintha, osati nyali zosasinthika.
