Tare da zurfafa tunanin ceton makamashi da kariyar muhalli, yin amfani da fitilar ledar duniya yana ƙara zama sananne.

Dangane da hasken gida, flush haske shine mafi mashahuri, Musamman jagoranci fitilar duniya. Kwatanta da fitilar gargajiya na gargajiya, kwan fitila mai jagoran duniya shine lumen sau 5 kamar yadda yake. Don haka amfani da kwararan fitila shine hanya mafi kyau don adana makamashin wutar lantarki.
