2. Halogen lamp - Wikipedia

   en.wikipedia.org/wiki/Halogen_lamp

   Halogen bulbs operate at high temperatures and the tall height of the lamps can bring them near flammable materials, such as curtains. [29] Some safety codes require halogen bulbs to be protected by a grid or grille, especially for high-power (1–2 kW) bulbs used in theatre , or by the glass and metal housing of the fixture, to prevent ...

3. Mazda (light bulb) - Wikipedia

   en.wikipedia.org/wiki/Mazda_(light_bulb)

   Mazda brand bulbs at the Edison and Ford Winter Estates Edison Mazda light bulb tester, logo by Maxfield Parrish, at the Corning Museum of Glass. Mazda was a trademarked name registered by General Electric (GE) in 1909 for incandescent light bulbs. The name was used from 1909 to 1945 in the United States by GE and Westinghouse. Mazda brand ...

4. Neon lamp - Wikipedia

   en.wikipedia.org/wiki/Neon_lamp

   A small electric current (for a 5 mm bulb diameter NE-2 lamp, the quiescent current is about 400 μA), which may be AC or DC, is allowed through the tube, causing it to glow orange-red. The gas is typically a Penning mixture , 99.5% neon and 0.5% argon , which has lower striking voltage than pure neon, at a pressure of 1–20 torrs (0.13–2.67 ...

5. Incandescent light bulb - Wikipedia

   en.wikipedia.org/wiki/Incandescent_light_bulb

   Electric current is supplied to the filament by terminals or wires embedded in the glass. A bulb socket provides mechanical support and electrical connections. Incandescent bulbs are manufactured in a wide range of sizes, light output, and voltage ratings, from 1.5 volts to about 300 volts.

6. Bi-pin lamp base - Wikipedia

   en.wikipedia.org/wiki/Bi-pin_lamp_base

   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 ...

7. Multifaceted reflector - Wikipedia

   en.wikipedia.org/wiki/Multifaceted_reflector

   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 ...
