2. High-intensity discharge lamp - Wikipedia

   en.wikipedia.org/wiki/High-intensity_discharge_lamp

   HID Lamp Color Temperature Range. HID lamps produce different colors of light primarily through the use of various metal additives in the lamp's arc tube and the physics of the gas discharge process. [11] Metal Additives: HID lamps contain an arc tube filled with a mixture of gases, including a noble gas (like xenon). These metal additives are ...

3. Mercury-vapor lamp - Wikipedia

   en.wikipedia.org/wiki/Mercury-vapor_lamp

   A 175-watt mercury-vapor light approximately 15 seconds after starting. A closeup of a 175-W mercury-vapor lamp. The small diagonal cylinder at the bottom of the arc tube is a resistor which supplies current to the starter electrode. A mercury-vapor lamp is a gas-discharge lamp that uses an electric arc through vaporized mercury to produce ...

4. Gas-discharge lamp - Wikipedia

   en.wikipedia.org/wiki/Gas-discharge_lamp

   A flicker light bulb, flicker flame light bulb or flicker glow lamp is a gas-discharge lamp which produces light by ionizing a gas, usually neon mixed with helium and a small amount of nitrogen gas, by an electric current passing through two flame shaped electrode screens coated with partially decomposed barium azide. The ionized gas moves ...

5. Sodium-vapor lamp - Wikipedia

   en.wikipedia.org/wiki/Sodium-vapor_lamp

   Low-pressure sodium lamps only give monochromatic yellow light and so inhibit color vision at night. Single ended self-starting lamps are insulated with a mica disc and contained in a borosilicate glass gas discharge tube (arc tube) and a metal cap. [3] [4] They include the sodium-vapor lamp that is the gas-discharge lamp in street lighting. [5 ...

6. NEMA wattage label - Wikipedia

   en.wikipedia.org/wiki/NEMA_wattage_label

   Additionally, various colors are used to identify what type of lamp the fixture uses. A yellow sticker indicates the lamp is a sodium vapor lamp (HPS/LPS). A blue sticker indicates the lamp is mercury vapor (MV). A red sticker indicates the lamp is metal halide (MH). A sticker that is half-red and half-white indicates a pulse start metal halide ...

7. Xenon arc lamp - Wikipedia

   en.wikipedia.org/wiki/Xenon_arc_lamp

   A xenon arc lamp is a highly specialized type of gas discharge lamp, an electric light that produces light by passing electricity through ionized xenon gas at high pressure. It produces a bright white light to simulate sunlight , with applications in movie projectors in theaters , in searchlights , and for specialized uses in industry and research.
