What is the need for fluorescent material?
Fluorescent materials are used in illumination, displaying, solid state lasers,light communication,light memory and so on.

Fluorescence is glowing, or giving off light.
Is it possible for a fluorescent material to emit radiation in the ultraviolet region after absorbing visible light?
Technically yes. There's a phenomenon called "two-photon absorption" that allows this to happen.
Answer for USA, Canada and countries running a 60 Hz power supply service. . No, check the inside of the fixture and look for a label that states "good for continuous row w…iring." If you find this the fixture is approved to be used as a raceway providing that the fixtures are all bolted together end to end. The wiring should be done with wire good for use in 90 o heat as there is a heat build-up from the ballasts. As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed. . Before you do any work yourself, on electrical circuits, equipment or appliances, always use a test meter to ensure the circuit is, in fact, de-energized . IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB SAFELY AND COMPETENTLY REFER THIS WORK TO QUALIFIED PROFESSIONALS.
Fluorescent material immediately glows when exposed to ultravioletradiation, that is it fluoresces. Phosphorescent material slowlyabsorbs and re-emits the radiation it absorbs…. This enablesphosphorescent material to absorb visible light spectra to "glow inthe dark" at a later time.
it absorbs the ultraviolet radiation and gives out visible light
Fluorescent fixtures can be used with a variety of voltages.
The electricity excites the florescent materials causing them to glow and give off light. Early light bulbs are incandescent or give off light with more heat than florescent b…ulbs which use much more electricity to make the metal filament glow with also much heat given off.
Fluorescent material glows under ultraviolet, not infrared light.

The correct voltage should be printed on the light bulb.
The ballast of a fluorescent lamp (whether modern electronic or conventional large inductance) will cause a kickback voltage when the lamp starts up that causes electrical bre…akdown and destruction of the standard dimmer's Triac (a solid state switch). There are some special electronic ballasts that don't do this and will work with ordinary dimmers (just don't expect a linear dimming effect like you got with an incandescent bulb). The special dimmers that work with ordinary ballasts use special high voltage switching circuits with extra protection components to prevent this damage. This makes them more expensive.
They are sort of related; however, glow in the dark materials are actually referred to as phosphorescent. The whole idea behind photoluminescence is that a material absorbs ra…diation (light) and then re-emits it. Phosphorescent materials absorb light, but release it at a much slower rate. Therefore, they absorb light when they are exposed to it, and then continue releasing it after the light source is removed. Fluorescence, on the other hand, is a material that that absorbs ultraviolet radiation (such as light from a black light) and then releases visible light.
The voltage of your area is what determines the operating voltage of all equipment. Equipment from other countries usually has to use a transformer to get the correct voltage.… The voltage on a fluorescent fixture is printed on the ballast of the fixture. See if the voltage on the ballast matches the supply voltage of the system that you are going to use to operate the fixture.
Not normally - the idea behind florescence is higher energy light(ultra-violet) powers lower energy light (visible light).
