A neon lamp (also neon glow lamp) is a miniature gas discharge lamp that typically contains neon gas at a low pressure in a glass capsule.
Neon's scarcity precluded its prompt application for electrical lighting along the lines of Moore tubes, which used electric discharges in nitrogen and which were commercialized in the early 1900s.
Around 1917, Daniel McFarlan Moore, then working at the General Electric Company, developed the neon lamp, which has a very different design than the much larger neon tubes used for neon lighting. A small electric current, which may be AC or DC, is allowed through the tube, causing it to glow orange-red. When the current through the lamp is lower than the current for the highest-current discharge path, the glow discharge may become unstable and not cover the entire surface of the electrodes.[dubious – discuss] This may be a sign of aging of the indicator bulb, and is exploited in the decorative "flicker flame" neon lamps. The potential needed to strike the discharge is higher than what is needed to sustain the discharge. In comparison with incandescent light bulbs, neon lamps have much higher luminous efficacy. Most small neon (indicator-sized) lamps, such as the common NE-2, break down at between 90 and 110 volts. Neon lamps with several shaped electrodes were used as alphanumerical displays known as Nixie tubes.
In AC-excited lamps, both electrodes produce light, but in a DC-excited lamp, only the negative electrode glows.
Neon indicator lamps are normally orange, and are frequently used with a coloured filter over them to improve contrast and change their colour to red or a redder orange, or less often green. The seventh place is occupied by an item that is not so expensive and surely more pleasant.

Only a thin region adjacent to the electrodes glows in these lamps, which distinguishes them from the much longer and brighter neon tubes used for signage. After 1902, Georges Claude's company, Air Liquide, was producing industrial quantities of neon as a byproduct of his air liquefaction business, and in December 1910 Claude demonstrated modern neon lighting based on a sealed tube of neon.
Because of this characteristic, electrical circuitry external to the neon lamp must limit the current through the circuit or else the current will rapidly increase until the lamp is destroyed.
However, while too low a current causes flickering, too high a current increases the wear of the electrodes by stimulating sputtering, which coats the internal surface of the lamp with metal and causes it to darken. When there is not enough current, the glow forms around only part of the electrode surface. Incandescence is heat-driven light emission, so a large portion of the electric energy put into an incandescent bulb is converted into heat. This feature enables their use as very simple voltage regulators or overvoltage protection devices.
Called "tuneons" in 1930s radio sets, they were fitted as tuning indicators, and would give a brighter glow as the station was tuned in correctly.
These have since been replaced by other display devices such as light emitting diodes, vacuum fluorescent displays, and liquid crystal displays.
Thus a neon lamp can be used to distinguish between AC and DC sources and to ascertain the polarity of DC sources. While the electrical operating characteristics remain similar, the lamps light with a bluish glow (including some ultraviolet) rather than neon's characteristic reddish-orange glow.

The term "neon lamp" is generally extended to lamps with similar design that operate with different gases. Convective currents make the glowing areas flow upwards, not unlike the discharge in a Jacob's ladder.
Non-incandescent light sources such as neon light bulbs, fluorescent light bulbs, and light emitting diodes are therefore much more energy efficient than normal incandescent light bulbs. In the 1960s General Electric (GE), Signalite, and other firms made special extra-stable neon lamps for electronic uses.

Novelty glow lamps with shaped electrodes (such as flowers and leaves), often coated with phosphors, have been made for artistic purposes. Ultraviolet radiation then can be used to excite a phosphor coating inside of the bulb and provide a wide range of various colors, including white.[15] A mixture of neon and krypton can be used for green glow, but nevertheless "green neon" lamps are more commonly phosphor-based.
Neon glow lamps were very common in the displays of electronic instruments through the 1970s; the basic design of neon lamps is now incorporated in contemporary plasma displays.
Larger neon sign sized lamps often use a specially constructed high voltage transformer with high leakage inductance or other electrical ballast to limit the available current. A photoionization effect can also be observed here, as the electrode area covered by the glow discharge can be increased by shining light at the lamp. Green neon[clarification needed] bulbs can produce up to 65 lumens per watt of power input, while white neon bulbs have an efficacy of around 50 lumens per watt.
They even devised digital logic circuits, binary memories, and frequency dividers using neon lamps.[7][8][9][10][11][12][13][14] Such circuits appeared in electronic organs of the 1950s, as well as some instrumentation.
See especially the section "Logic and Computer Applications of Glow Lamps," which presents circuits using neon lamps in "and" gates, "or" gates, inverters, pulse generators, flip-flops, and ring counters. The electrodes would glow brightly in red or blue, depending on the gas, and the lamps lasted for years.
Once lit, the voltage required to sustain the discharge is significantly (~30%) lower than the striking voltage. At least some of these lamps had a glow concentrated into a small spot on the cathode, which made them unsuited to use as indicators. Because of their comparatively fast response time, in the early development of television neon lamps were used as the light source in many mechanical-scan TV displays.
That is why, if now you’re desperately rushing in search of a cool present and you cannot find one, you’re saved.

Since the electrodes could take almost any shape imaginable, a popular application has been fanciful decorative lamps.
They were also used for a variety of other purposes; since a neon lamp can act as a relaxation oscillator with an added resistor and capacitor, it can be used as a simple flashing lamp or audio oscillator.
A variant of the NE-2 type lamp, the NE-77, had three parallel wires (in a plane) instead of the usual two.
When driven from an AC source, both electrodes will glow (each during alternate half cycles).
These attributes make neon bulbs (with series resistors) a convenient low-cost voltage testers; they determine whether a given voltage source is AC or DC, and if DC, the polarity of the points being tested. Higher power devices, such as mercury-vapor lamps or metal halide lamps use a higher current arc discharge.
