The usual name for for strip lighting in which a gas discharge tube, coated on the inside with a phosphorescent paint glows when power is applied. This light flickers at a frequency which matches the AC current applied i.e. 50Hz in the UK.
emitting light during exposure to radiation from an external source
brilliantly colored and apparently giving off light; "fluorescent colors"
A type of cool, glareless light produced by the fluorescence of gas.
describes matter that absorbs light then emits it at a longer wavelength
Term used to describe lamps that produce light through the illumination of phosphorous coating by gas-produced ultraviolet radiation.
A dye that will absorb light of one colour such as blue and emit another colour such as green.
The lighting fixtures that provide an even, soft illumination, typically in kitchens and bathrooms. Fluorescent tubes are more efficient than traditional incandescent bulbs.
a glass tube coated on the inside with a fluorescent substance that gives off light. Acceptable for starting seeds and low light plants.
Energy efficient bulbs, using 20-40% less electricity than standard incandescent bulbs.
Having the property of emitting light of a specific wavelength when illuminated by light of another specific shorter wavelength.
A tubular electric lamp having a coating of fluorescent material on its inner surface and containing a vapor which when hit with electrons provides ultraviolet light, which causes the material to emit visible light. The coating determines the light spectrum emitted. For plants, a wide or full spectrum bulb is used. These bulbs come in the standard 4-ft. and 2-ft. tubes, which are effective up to 16" from the soil. The new coil and other styles of bulbs may vary in height limits.
A high effiency lamp utilizing an electric discharge through low pressure mercury vapor to produce ultra-violet energy. UV excites the phosphorus lining which transforms into visible light.
Possessing the property of fluorescence, exhibiting strikingly bright and vivid colors.
A class of pigments which, when exposed to visible light, emit light of a different wavelength producing a bright appearance.
1. Absorbing light energy and then releasing it almost immediately. 2.A short-lived glow of light not caused by high temperature.
light produced by the electrical stimulation of a gas or vapour. Fluorescent lights have a similar effect on opal as a bright cloudy day--they do not properly bring out the colours in opal
A bright vivid colour that glows under a black light.
A low-pressure lamp that has a phosphor coating that transforms ultraviolet energy into light. Although efficient they are physically very large.
The ability to emit light when struck by electrons or other radiation.
A bright vivid color that glows under a black light.
A lighting system which works by creating electric arcs inside a gas rich tube to produce ultraviolet light, then converting this to visible flourescent light by its passage through a layer of phosphor on the inside of the glass.
a type of low wattage light, very useful for rooting cuttings and early vegetative growth. Usually come in tube format and produce low heat.
means "glowing with light." Fluorescent light bulbs are far more efficient and last far longer than standard incandescent light bulbs.
Having the quality of appearing to take in radiation and send it back out as visible light. Refers to the appeared on some specialty colors of paint, vinyl or screen printing ink.
