It is a lamp which gives off ulraviolet light while blocking out white light, that causes fluorescent minerals to react.

A form of low pressure mercury discharge lamp, the common fluorescent lamp is used throughout industrial and commercial installations for both general and specialised lighting

Is a tubular lamp filled with mercury vapour at a low-pressure, and a small amount of an inert gas such as argon or krypton to aid starting and arc regulation. Electrodes are sealed into each end, and the light produced by the discharge is predominantly in the ultra-violet region. The inside of the tube is coated with fluorescent powders or phosphors, which the ultraviolet light excites to produce visible light. A wide range of colours and efficacies is available using different phosphors, individually or in combination.

A lass tube filled with mercury gas and coated on its inner surface with phosphors. When the gas is charged with an electrical current, radiation is produced which in turn energizes the phosphors, causing the phosphors to glow.

Lamp that gives off ultraviolet light while blocking out white light, which causes fluorescent minerals to react.

A type of electric discharge lamp in which a phosphor coating transforms ultraviolet energy (created by electric discharge) into visible light. Fluorescent lamps are the most common lamp used in commercial office applications. Often chosen for its ability to combine energy efficiency with good color rendering.

This form of lighting constitutes approximately 70% of the electrical light used in North America. Efficacy rates (lumens output / watts input) for fluorescent lamps range from 50-80 lm/w.; much higher than that of incandescent bulbs.

electric lamp using a tube coated with fluorescent material, which has low lumen and heat output; A fluorescent lamp is excellent for rooting cuttings.

A low pressure mercury, electric-discharge lamp in which phosphor coating transforms ultraviolet energy (created by electric discharge) into visible light.

A tubular electric lamp that is coated on its inner surface with a phosphor and that contains mercury vapor whose bombardment by electrons from the cathode provides ultraviolet light which causes the phosphor to emit visible light either of a selected color or closely approximating daylight.

A light source that instead of ``burning” as incandescent bulbs do, uses an ionization process to produce ultraviolet radiation. This turns into visible light when it hits a coating on the tube’s inner surface.

A very energy efficient type of lamp that produces light through the activation of the phosphor coating on the inside surface of a glass envelope. These lamps come in may shapes, wattages, and colors.

A lamp containing mercury under low pressure, relative to high-intensity discharge lamps. The mercury is ionized by an electric arc, producing ultraviolet energy, which in turn, excites phosphors coating the inside of the lamp to fluoresce or glow.

A discharge lamp in which a phosphor coating transforms ultraviolet energy into visible light. Fluorescent lamps are good for starting seedlings and rooting cuttings, but do not have enough intensity to sustain aggressive growth in plants in the later stages of life, and are not efficient enough in their conversion of electrical power to lumens of light output.

is a type of artificial light source in which the mercury vapour generated by a low wattage arc strikes the phosphor material to emit light. It is popularly used in indoor applications.

A light source consisting of a tube filled with argon, along with krypton or other inert gas. When electrical current is applied, the resulting arc emits ultraviolet radiation that excites the phosphors on the inside of the lamp wall, causing them to radiate visible light.

A type of lamp which converts UV light into visible light through fluorescence. Fluorescent lamps are one of the least commonly used lamps on stage. See Also: Fluorescence Ultra Violet

One in which electric discharge of ultraviolet energy excites a fluorescing coating (Phosphor) and transforms some of that energy to visible light.

a type of gas discharge lamp that uses an electric charge to excite gaseous atoms in a glass tube; these atoms emit ultraviolet (UV) radiation that is absorbed by a phosphor coating on the walls of the lamp tube; the phosphor coating then transforms the UV light to visible light.

A high efficiency lamp utilizing an electric discharge through low pressure mercury vapor to produce ultraviolet (UV) energy. The UV excites phosphor materials applied as a thin layer on the inside of a glass tube which makes up the structure of the lamp. The phosphors transform the UV to visible light.

An electrical discharge ionizes the gas inside the lamp, producing ultraviolet radiant energy which excites the phosphor coating on the inside of the glass. The phosphor coating then emits visible light.

A glass tube filled with mercury gas and whose inside surface is coated with phosphors. Once the gas is charged with electrical current, radiation is produced which then energizes the phosphors and causes them to glow.

A lamp producing light by exciting a phosphor with a plasma with the phosphor re-emitting the energy as light.

A low-pressure mercury electric-discharge lamp in which a fluorescing coating (phosphor) transforms some of the ultraviolet energy generated by the discharge into light.

A fluorescent lamp is a gas-discharge lamp that uses electricity to excite mercury vapor in argon or neon gas, resulting in a plasma that produces short-wave ultraviolet light. This light then causes a phosphor to fluoresce, producing visible light.
