Before heading off to the outlets, verify what sort of bulb you wish to replace. Nearly all of light bulbs are described by a system of collection designations. Out there with screw and bayonet bases, which have the designations Exx and Bxx respectively. The xx refers back to the base’s diameter in millimetres. These are sometimes used as floodlights and downlights. They are numbered by the scale of the bulb’s diameter in millimetres, R80 for instance. PAR38 is a standard type; the 38 is the diameter of the bulb in multiples of eighths of an inch. PAR38 bulbs are 121mm broad. MR16s have two thin pin bases (referred to as GU5.3 bases), whereas GU10s often have thick turn and lock "top-hat" bases. The primary difference between them is GU10s run at 240V, while MR16s run on 12V and require an exterior transformer. There are MR16 lamps out there with GU10 flip and lock bases.
