So guys before we start, let’s get things clear. There is a difference between E26 and E27 Edison screw base. It’s only a 1mm difference between the threads of E26 and E27 but it’s important to choose the right screw.
Such difference between E26 and E27 is historically set by grid voltage systems from 120V to 240V. Usually, you won’t differ these two holding in hands so double check packaging making before making a purchase. All of the reviewed 100W LED bulbs are USA E26 certified.
