Amakhanda amaphaneli amathathu e-aluminium eholwa ngamalambu egaraji angashintshwa, ikhanda ngalinye elikhanyayo lingagoqwa lifike ku-90°. I-engeli ephezulu yokumboza ingafinyelela ku-360°, asikho isidingo sokuthenga amalambu esitolo engeziwe, lezi zibani zegaraji eziholayo zizovala indawo ebanzi.Ngesisekelo esijwayelekile se-E26/E27, yenza ukufakwa kwalezi zibani zesitolo eziholayo kube lula njengokukruqa ekukhanyeni. isibani, kodwa isicelo esikhanyayo nesibanzi kunesibani. Kuwukukhanya okusebenzayo okuholayo okunemisebenzi eminingi kwegalaji, indawo yokusebenzela, inqolobane, indawo yokugcina impahla, amagumbi angaphansi, ihhovisi, isuphamakethe, isiteshi, ihhotela, indawo yombukiso, amagumbi emishini, izindawo zokusebenza zezimboni, nanoma iyiphi indawo edinga ukukhanyiswa.
