These lamps use a bi-pin connector for power: 12-volt MR11 bulbs usually use a GU4 base, and 12-volt MR16 bulbs usually use a GU5.3 base. The common 12-volt MR16 lamps, therefore, require a ferromagnetic or electronic transformer —sometimes misnamed as a ballast —to convert the 120- or 230-volt mains voltage to the extra-low voltage ...
The suffix after the G indicates the pin spread; the G dates to the use of Glass for the original bulbs. GU usually also indicates that the lamp provides a mechanism for physical support by the luminaire: in some cases, each pin has a short section of larger diameter at the end (sometimes described as a "peg" rather than a "pin" [2]); the socket allows the bulb to lock into place by twisting ...
Left to right: MR16 with GU10 base, MR16 with GU5.3 base, MR11 with GU4 or GZ4 base HIR/IRC "HIR" is a GE designation for a lamp with an infrared reflective coating. Since less heat escapes, the filament burns hotter and more efficiently. [138] The Osram designation for a similar coating is "IRC". [139]
In areas following the U.S. National Electrical Code, general-use lamps over 300 W cannot use an E26 base and must instead use the E39 base. Medium Edison screw (MES) bulbs for 12 V are also produced for recreational vehicles. Large outdoor Christmas lights use Intermediate base, as do some desk lamps and many microwave ovens.
In 2011, the last version to use a 100-watt incandescent light bulb was replaced by a new version with a dedicated heating element, named the Easy-Bake Ultimate Oven. The replacement was due to the availability of alternatives to the incandescent light bulbs that heated previous versions of the Easy-Bake Oven. [23]
A bayonet mount A bayonet mount before and after insertion Early-19th century socket bayonet Socket of a bayonet. A bayonet mount (mainly as a method of mechanical attachment, such as fitting a lens to a camera using a matching lens mount) or bayonet connector (for electrical use) is a fastening mechanism consisting of a cylindrical male side with one or more radial pegs, and a female receptor ...
The MR20DE, a 2.0 L (1997 cc) engine, was the first MR series engine developed by Nissan as a replacement for the QR20DE. It is an undersquare engine, its bore and stroke being 84 mm × 90.1 mm (3.31 in × 3.55 in), respectively. It was first introduced in the Lafesta and Serena MPVs and Renault Samsung SM5 in early 2005.
