UV bulbs are usually fluorescent tubes with the normal white phoshor powders removed.
Heaters at each end of the tube excite electrons to 'boil' off the wires. A high voltage is applied via an inductor or choke across the tube ends which sets up a flow of electrons through the tube called a plasma. This is the 'electric blue' of a miniature lightning bolt and emits UV light.

How can you see the UV light in laminar air flow otherwise usually you cant see the uv ray?
UV bulbs usually have a coating on the inside that glows when the light is on, providing indication in the visible light part of the spectrum.
Are UV light and UV rays the same thing?
Yes, UV light and UV rays are the same thing, light emit "rays."
Why was argon gas chosen for a light bulb?
Argon is often used when an inert atmosphere is needed. It is used in this way in incandescent light bulbs to stop oxygen from corroding the filament. Argon is used in fluorescent tubes and low-energy light bulbs. A low-energy light bulb often contains argon gas and mercury. When it is switched on an electric discharge passes through the gas, generating UV light. The coating on the inside surface of the bulb is activated by the UV light and it glows brightly.
How do you get a UV light?
you go to a beauty shop and ask for a UV light
How does UV light treatment work?
Ultraviolet (UV) light treatment is used primarily in cases of severe psoriasis that have not responded to other medications or in cases affecting large portions of the body.
How do Plant light bulbs work?
The fluorescent type of light bulbs (correctly called lamps) have a phosphor that besides emitting visible light (400 to 750 nm) also emits some UV enengy in the UV-A range. Plants need visible light and some UV-A to be effective.
What light is responsible for growth in plants?
Any light that contains or gives off UV rays. (Light bulbs don't work)
What are the best brands of UV light bulbs?
The best UV light bulbs are made by Sylvania and Philips. The downside of the story is that UV light bulbs of those brands are among the most expensive on the market.

What are examles of radiation and uv light?
Some examples of radiation and UV light include sunlight and ultraviolet light bulbs. Each produce special wavelengths of light which are not seen by the naked eye.
Are vampires scared of lights?
they are not scared of artificial light for example light bulbs but they are scared of sunlight due to the UV rays
Why does incandescent light not glow on material?
Incandescent light bulbs do not emit much Ultraviolet light. Strip lights and compact fluorescent low energy light bulbs do. The whiteners added to white fabrics react to UV light and glow due to fluorescence.
Where to get uv light bulbs?
UV lamp, also called Black-light Lamp, device for producing electromagnetic radiations in the wavelengths between those of visible light and X-rays. The Sun's rays are rich in such radiation, sometimes referred to as black light because it is not visible to the unaided eye.
Do light bulb emit UV?
Florescent lams do ... museums use a tubular UV filter over those bulbs to prevent damage to two-dimensional paper ephemera.
What objects can give off UV rays or waves besides the usage of the sun?
Spectrum gives UV rays or waves besides the usage of the sun
Do televisions use light bulbs to work?
