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 ...
Available in numerous spot and flood beam spreads. Like all light bulbs, the number represents the diameter of the bulb in 1 ⁄ 8 of an inch. Therefore, a PAR 16 is 51 mm (2 in) in diameter, a PAR 20 is 64 mm (2.5 in) in diameter, PAR 30 is 95 mm (3.75 in) and a PAR 38 is 121 mm (4.75 in) in diameter. A package of four 60-watt light bulbs

Incandescent, halogen and HMI light sources use this design. Medium bi-post (G22) is used with film & stage lighting fixtures between 250 and 1000 watts. Mini bi-post (G4-G6) Common types: G4 – 4 mm (0.15748 in) pin spacing GU4 & GZ4 – same as G4 and only denote what lamp mount clip is needed to hold the actual light bulb in place
E10 bulbs are common on battery-powered flashlights, as are bayonet mounts (although those are usually held in with a circular flange located where the base meets the glass envelope of the bulb). The E11 base is sometimes used for 50/75/100 Watt halogen lamps in North America, where it is called the "mini-can", and tighter threads are used to ...
The wires are usually inserted into a plastic base that the bulb is mounted in, and which is often narrower at the tip than at the bulb, giving it a wedge shape and usually ensuring a tight connection, depending on manufacturing tolerances. Some bulbs have no plastic base, and the wires are simply bent up to the sides of the bulb's glass base.
The bulb is usually made from Pyrex or synthetic quartz. Incandescent lamps also have a base. The base screws into a socket and serves as an electrical contact point for the socket and the filament inside. For the most part, higher watt bulbs will use larger bases. Incandescent bulbs for stage lighting may have pins on the bottom instead of a ...
One controls the three-way center bulb, and the other turns on one, two, or all three (or four) of the peripheral bulbs. The center bulb may be very high power (often a three-way, 100-200-300 watt bulb), where the others are usually 60 watts or less. Some models have a night light in the base operated by a foot switch. One model turns the ...
