The supply voltage V S must be greater than the bulb breakdown voltage V b or the bulb can never conduct. [7] Most small neon lamps have breakdown voltages between 80 and 150 volts, so they can operate on 120 Vrms mains voltage, which has a peak voltage of about 170 V.
Fluorescent lamp tubes are often straight and range in length from about 100 millimeters (3.9 in) for miniature lamps, to 2.43 meters (8.0 ft) for high-output lamps. Some lamps have a circular tube, used for table lamps or other places where a more compact light source is desired.

Very similar to the A shape are the P shape ("A bulb having a spherical end section, and a conical mid section, the sides of which are tangent to the curve of the spherical section"), and its PS variant ("Tubular neck section below the bulb and above the approximate reference line"). Philips L Prize bulbs count as A19 under Energy Star ...
The lamp-lighter switch and regulator avoided this by automatically regulating the lamps electrical current. [3] In an electric lighting system with an electric generator supplying current to several electric lamps in a Man and Sawyer electrical distribution system there was an independent electromagnetic safety switch of the electrical current.
