Labada nooc ee hababka iftiiminta waxay leeyihiin faa'iidooyin iyo faa'iidooyin iyaga u gaar ah.Farqiga u dhexeeya guddiga cidhifka ah iyo kan dambe ee iftiinka leh waa qaab-dhismeed, ma jiro saxan hage iftiin ah oo ku yaal guddida dambe, iyo saxanka hagaha iftiinka (PMMA) guud ahaan wuxuu leeyahay gudbin ku saabsan 93%.
Maaddaama masaafada u dhaxaysa il kasta oo LED ah ay aad u weyn tahay, masaafada u dhaxaysa LED-yada iyo saxanka faafinta PC-ga waa in ay ahaataa mid aad u weyn, si aanu gobol mugdi ahi u samaysan marka laambadku shidan yahay.
Iftiinka ay shidayso kuul-laambad cidhif leh waxa ka tarjumaysa filimka iftiimaya ee saxanka hagaha iftiinka, waana la shiiday.Ka dib markaad dhex marto saxanka hagaha iftiinka, qulqulka iftiinka wuxuu yeelan doonaa khasaare gaar ah.
Nuxurka laambada dambe ee iftiinka ayaa ah in dhumucda laambaddu guud ahaan tahay 3.5cm-5cm, laakiin mid kale oo dhumucdiisu tahay 8mm-12mm, kaas oo aad uga dhumuc weyn marka loo eego muraayadda cidhifka ah, waxay ku kici doontaa xirmo iyo kharash badan, laakiin nalka hoose.
Faa'iidada iftiinka muraayadda gadaal waa in leh lumen sare oo ku salaysan noocyo isku mid ah oo LEDs ah.
