A flourescent 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.
Florescent light bulbs contain gases that get ionised when electricity is passed through it and they begin to emit light known as fluorescent light.
This emission of light takes place due to increase in energy level of the protons (nucleus) rather than the electrons. This difference in energy gets emitted as light.
Mercury vapor is the important one. There may be other gases as well.
The most common gas used inside fluorescent lamps is Mercury vapour.

Yes, and not just because of the glass it is made of. The bulbs have mercury inside of them which can make you ill.
The weight of one 8 foot fluorescent light bulb is 1.2 pounds. Fluorescent light bulbs are available in many colors and color temperatures.
The fluorescent light bulb more efficiently converts electricity to light resulting in less heat produced. But in winter, heat being produced is not exactly a bad thing. Besides, fluorescent light bulbs are more expensive and have heavy metals in them, making them more toxic.

The minerals glow.
Light in fluorescent bulbs occurs when electricity excites the mercury vapor inside the tubular glass bulb.
current flows and we have light from bulb....
Fluorescent lights glow because of an electric discharge in a glass tube that causes mercury atoms to emit ultraviolet light. The inside of the tube is coated with phosphor, which absorbs the ultraviolet light and then re-emits visible light.
Well.. the difference is that fluorescent light isn't natural and natural light isn't fluorescent . its not rocket science (:
A ballast is an electrical component used with a fluorescent bulb (or mercury vapor lamp or arc lamp) to conduct electricity at each end of the tube. Compact fluorescent light bulbs are dependent on ballast because they use a gas to create light. when the gas is excited by electricity, it emits invisible ultraviolet light that hits the white coating inside the fluorescent bulb. The coating changes the ultraviolet light into light you can see.
You can go to one of those motor home supply stores and purchase a 12 volt fluorescent light assemblies. Otherwise, if you want to use a conventional fluorescent light you'll need to use an inverter.
Anything that excites the gas in a fluorescent will make it light. Static electricity from the carpet will cause compact fluorescent to light.
Apart from no, your question has no simple answer. Fluorescent lamps need a few kV to start them and have a 90V drop when running. All of that is provided by the "gear" needed to run a fluorescent lamp. In a compact fluorescent (CFL), the gear is inside the cap.
fluorescent bulbs have mercury in them. There are heaters at the ends of the bulb that vaporizes the mercury to allow the light to be produced ( the fluorescence on the inside of the bulb is what actually glows). If the bulb is cold you do not get the ionization of the mercury to cause the fluorescent powder inside the bulb to glow, or it just glows a small amount.
