1, E represents the Edison screw bulb, 26, 27 refers to the nominal diameter of the bulb thread. E26 is the American standard specification, E27 is the European standard specification. Our country also adopts European standard specifications;
2, E26 is less than half of the spiral of E27, the former is 110V, the latter is 220-240V, although there is not much difference in use, but if E26 is used in European countries, the life expectancy is short, it is easy to predict the human body. Hazard
3, E26 E27's caliber is not the same size, one is 26, one is 27, you can also use the bulb for comparison test: You can use an E26 bulb to test; the hand that is tighter is E26, Relatively loose is E27; vice versa can also be tested with E27 bulb: the tighter is E26, the better rotation is E27! You can also distinguish from the certification symbol!
Highly remember that the E27 is a little higher;
4. E26 and E27 not only have different appearances, E26 usually has connecting lines, but E27 usually connects the wires through threaded binding posts; the two are different standard lamp holders, E26 is American standard, E27 is based on IEC standard system; export, certification, and then mixed.
If you are reluctant, the two specifications can sometimes be mixed, but sometimes there are cases of poor contact!
