What is a uv light bulb?
a UV light bulb is a light bulb that emits UV light. UV light is what the sun emits. UV light is bad for skin if on too long.

Anyone can purchase a UV light bulb at any known hardware store. These would include stores such as Lowe's, Sears, ACE hardware, Dixieline, and Home Depot.
If it emits UV, yes...tanning beds do
ionized mercury vapor emits UV light. phosphor coating on inside of tube absorbs UV light and emits visible light. visible leaves tube.
A fluorescent light bulb contains a gas which produces UV light when it comes in contact with electricity. Contrary to a normal light bulb this does not create any heat and is far more energy efficient.
Yes actually, most of them do. The way they are backlit causes the to emit UV light. Most use a flouescent bulb and we all know those emit UV rays. wearsunglsses :)
A black light is a UV emitting bulb. There are other types of UV bulbs, but most have very specific uses, such as: bug lights, tanning bed lamps, drying lamps for lithographic applications and printing, and medical diagnosis. All lamps--incandescent, fluorescent, mercury vapor, tungsten, etc.-- emit some range of UV light, so could be considered UV lamps, but that is not their specific purpose, and the amounts or levels vary widely.
A real one is black, because you can't see UV light. But most that are for sale tend to be dark blue so that you can tell that they're turned on.
A fluorescent light bulb is filled with argon gas and mercury vapor. Electricity is passed between two naked contact points within the tube. This super heats the mercury vapour turning it into a plasma. this in turn gives off invisible UV light. The glass of the bulb is coated with a phosphor which fluoresces in the presence of UV light. This in turn produces visible light.
red bulb for the night time and white bulb pluse uv tube for the day.
Pet urine can be difficult to clean completely. If you have gotten urine on a UV light, turn the light off, and clean the bulb gently with an enzymatic product from the pet store.
actually, the rare-earth phosphors lining the tube.
Florescent lams do ... museums use a tubular UV filter over those bulbs to prevent damage to two-dimensional paper ephemera.
No; a black light or UV light is a light bulb that has a phosphor coating that blocks out nearly all light and produces a dark violet colour and produces UV radiation, this can then be used to make fluorescent,phosphor coated or white coloured objects glow.
No, they work by passing an electric current through a noble gas which creates the light. Actually CFLs do have 2 small starter filaments but they are turned off automatically once the bulb starts. Also the noble gas (usually argon) is inert and generates no light, what produces the light is a tiny amount of mercury vapor (emits UV light) and a phosphor coating on the inside of the bulb (converts the UV to visible… Read More
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… Read More
It will have the same effect as a flourescent light bulb. Its basically the same light. On a white flourescent light bulb, the inside has been frosted white to give off a white light. Without this coating, its the same as a black light. The uv rays are the same.
The UV light is different to that of fluorescent light. The UV originates from the sun. The latter one does not.
Yes, UV light and UV rays are the same thing, light emit "rays."
"Ozone lamps" are UV light sources that use quartz sleeves between the environment and the mercury plasma that produces the light, and does not have the titanium dioxide coating that absorbs short wave UV and makes lots of visible light (the usual fluorescent light bulb does this). Normal glass will absorb too much of the UV. Ozone in the tropopause is produced by 215nm (or more energetic) UV light, and mercury vapor lamps produce some… Read More
It would probably takes weeks to get enough UV exposure from a regular white light fluorescent bulb if any.
Antifreeze / coolant has a UV dye in it (unless it is "GM dexcool", then you would have to buy a dye and put it in your radiator) . Get a "black light bulb" and put it in your shop light and look around your hoses. They make special flashlights with UV bulbs, etc, but just go to the hardware store or walmart and get a bulb.
Depends on how they are being used. In an incandesent bulb, the most common lightbulb, electrons are fed through a tungsten filiment in a vaccum, which causes the filiment to glow and emit light and heat. Florscents work differently. In a florscent, uv waves hit a coating inside the bulb, which then illuminates and produces light. In this case the electrons are powering the device that emits the uv waves.
Fluorescent bulbs contain a low pressure mercury vapour. The electricity excites the gas which emits UV light. The inside of the glass is coated with a phosphor. The UV light excites the phosphor which emits visible light. When you rub the bulb with a piece of nylon you are rubbing electrons from one material to the other (i think from nylon to bulb). This results in static electricity which excites the mercury vapour in much… Read More
The minimum recommendations for an adult bearded dragon is an area of 4x2x2 feet with a cool side and a warm side. The cool side should sit around 80 F and the basking spot should be about 95-105 F the UV light should be somewhere that the dragon can access and sit within 6" of it. I acieve this with just a basking bulb uv bulb and a ceramic heater for night.
Fish tank light bulbs do not give out any significant amount of UVB, you really need to get a real UVB reptile bulb. You can get them at a great price online at www.bigalsonline.com. I attached a link to the UV bulb section
A UV active compound absorbs UV light, and a UV inactive compound does not (it is "transparent" to UV light).
There is no phosphorus in a fluorescent lamp, the coating is a compound called phosphor. phosphorus is an element that burns. phosphor is a compound that when excited by an electron beam, UV light, or x-rays glows in visible light. A fluorescent lamp is a mercury vapor UV (aka black light) lamp with a phosphor coating on the inside of the lamp tube to turn the invisible UV light to visible light.
When a fluorescent lamp is turned on, the electricity excites the mercury vapor inside the tube. UV light is produced. The UV light excites the phosphor coating. The phosphorus atoms relax by releasing a visible light. Since the light emitted by the phosphorus atoms is of a spread spectrum (the frequency is not fixed), the light appears whitish. To summarize, electricity is turned into light.
The Sun produces all types of light across the entire spectrum. However, the rays of the Sun that cause sunburns, and the light rays from a "black light" bulb, are ultraviolet light, or "UV".
you go to a beauty shop and ask for a UV light
It is different because the UV light is brighter then a normal light and it is like a laser. UV light is different to normal light because it is invisible and the wave length is smaller.
Typical light bulbs convert electrical energy into light and heat energy. The light (visible, IR and some UV) radiates away. Some we can see. The bulb heats up. This heat energy is radiated away and -- if it's not in a vacuum -- the heat is also carried away by convection.
You do not need a UV light for acrylics.You only use a UV light for an acrylic sealer or gel nails.
electircal or photo electrical energy. Photons are shot across from panel to another panel this sparking back and forth creates the light you see. Answer: Electricity is the energy input into a light bulb. It either heats afilamanet to produce heat and light, r excites the gas contained in the bulb (in flluorescent tube) to emit visible light directly or emit UV light which interacts with a phosphor coating in the tubes to emit light.
UV light for a swimming pool is a physical system. A "system" is placed after the pump and heater. Water passes by the UV light bulb and is sanitized. There are no chemicals generated, no disinfection by products, andUV destroys more bacteria, germs and virus than any other system.This is considered UV-C germicidal wavelength. Some Ozone generators use UV -B a lower wavelength to generate ozone. Though these systemsprovide significant sanitation close to the level… Read More
Not the average one, but they do have special ones (they are found in tanning beds). Those are essentially fluorescent tubes, but without the coating to convert UV into more visible light.
UV light can be turned into infrared light u dofus. DANJUIN
Will a 400watt UV black light bulb work on a normal Australian lamp I mean can the bulb withstand it or even work enough power for it to work?
A normal lampholder is probably unsuitable for a 400 W bulb because the heat generated is too much for the normal type of lampholder. The wiring will probably take the current but the heat is probably excessive. With many types of lamp most of the electrical power comes out as heat, with only a fraction as light or uv.
yes the UV light kills the fungus
UV light kills microorganisms, such as fungus and molds.
the temperature of a UV light is 10nm-400 degrees fahrenheit
no because it is uv
only in uv light
it varys from light bulb to light bulb.
Ozone absorbs UV light. It is present as ozone layer.
because UV light is different :)
When it absorbs UV light, it decomposes. It also replenishes it.
the nitrogenous bases of DNA absorbs UV light
yes uv light does kill listeria and does not hurt the food
