LED bulbs are available at most supermarkets, hardware stores, and specialised lighting and electrical retailers. Earlier than heading off to the shops, test what sort of bulb you need to exchange. Nearly all of mild bulbs are described by a system of collection designations. Obtainable 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 often used as floodlights and downlights. They are numbered by the size of the bulb’s diameter in millimetres, R80 for example. PAR38 is a common kind; the 38 is the diameter of the bulb in multiples of eighths of an inch. PAR38 bulbs are 121mm large. MR16s have two skinny pin bases (known as GU5.3 bases), whereas GU10s often have thick turn and lock "top-hat" bases. The primary distinction 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.
