MR16 is not a lamp holder, lamp type is GU5.3 or GX5.3, MR16 in MR is multi-faceted reflector lamp cup, 16 caliber, the unit is 1/8 inch, 16 is 2 inches, which is about 5cm. E27 is a kind of lamp specifications, Edison, Edison, American inventor is to his name. We commonly known as spiral lamp, 27 parts of the diameter of the screw head behalf, 27mm. There E40, E26, E14, E12, E10, E5, etc. specifications. In addition, we common one kind of lamp, B22d, known bayonet cap, B (bayonet, bolt), 22mm diameter, d (double, double electrode), there are also several other specifications and models, such as B15d so on. LED lights in a variety of applications are already in existence before the, LED lamp holders direct replacement for the early, so the majority followed the previous head size. As for the voltage problem in many countries worldwide (even in different regions of the same country) civil ac voltage and frequency are not the same. Basically, 100V/60Hz and 230V/50Hz can be roughly divided into two categories, North America, mainly 110V/60Hz, Japan, Taiwan 100V/60Hz, our country is 220V/50Hz, 240V/50HZ Australia is so. Plus the voltage fluctuation range is generally 10-15%. The lower voltage 100VAC is 100 * (1-15%) = 85V, 240V voltage limit is 230 * (1 +15%) = 265V. Some mobile devices or can not determine the ultimate use of voltage appliances and lighting for safe use, it made ​​the application of global voltage range types, the range is  85-265V.
