Incandescent bulbs have a shorter life than most other lighting, an important factor if replacement is inconvenient or expensive. Some types of lamp, including incandescent and fluorescent, emit less light as they age; this may be an inconvenience, or may reduce effective lifetime due to lamp replacement before total failure.

The Class 93 locomotive is a derivative of the Class 88 electro-diesel and Class 68 diesel locomotives, both of which were built by Stadler. [7] [13] As with Class 88 locomotives, Class 93s are designed as fast freight locomotives that use electric power while under the wires, but that are also capable of self-powered operations. [7]
In 1909, Wagner Electric started manufacturing their first automotive headlamp bulbs. Wagner Electric Company Strike, May 3, 1918. The International Association of Machinists held a strike at the Wagner Electric Company in St. Louis, Missouri from June 4 to October 7, 1918. [1] [2] Before it became part of a conglomerate, Wagner had three main ...
A planar transformer Exploded view: the spiral primary "winding" on one side of the PCB (the spiral secondary "winding" is on the other side of the PCB) Manufacturers either use flat copper sheets or etch spiral patterns on a printed circuit board to form the "windings" of a planar transformer, replacing the turns of wire used to make other ...
Fluorescent lamps in various embodiments. Since their introduction as a commercial product in 1939, many different types of fluorescent lamp have been introduced. Systematic nomenclature identifies mass-market lamps as to overall shape, power rating, length, color, and other electrical and illuminating characteristics.
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 ...
Virginia Transformer Corp (VTC) is the fourth largest power transformer manufacturer in North America, [citation needed] the largest US-owned. [1] It was established in 1971 to provide power transformers to the Appalachian mining industry. [1] Since then it has expanded to provide transformers across North America.
