What is the deference between incandescent and fluorescent lights?

An incandescent light uses electric current passing through a wire with a high resistance to current flow. That makes the wire very hot and it glows, producing the light.
A fluorescent light uses electricity to charge a gas in a tube. The charged gas glows, producing the light.
For the same amount of light, more electricity is needed in an incandescent light than in a fluorescent light, but developing and building fluorescent lights required more advanced technology than did incandescent lights.

How do fluorescent light bulbs help the environment?
Fluorescent lights help the environment by conserving energy and being more efficient.Traditional bulbs produce about 15 lumens per watt, while fluorescent bulbs produce between 50 to 100 lumens per watt. This makes fluorescents bulbs five or six times more efficient than traditional bulbs.Also, the concepts behind the two bulbs are different. Traditional, or incandescent bulbs create heat in order to create light, which wastes a lot of energy. Fluorescent bulbs use a gas containing argon and mercury vapor that creates ultraviolet photons.This helps the environment by not wasting resources.Alternative AnswerFluorescent lamps might lower your electricity bill, but they use more energy and resources to manufacture, compared with incandescent lamps. They also contain mercury and other toxins. So fluorescent lamps probably do more damage to the environment than incandescent lamps. So, if you want to save on your energy bills, use fluorescent lamps; if you want to protect the environment, then use incandescent lamps.
What is the difference between incandescent and fluorescent light bulbs?
Incandescent lightbulbs have an electrical circuit that passes through a tungsten wire. As the electricity flows, the tungsten is heated up to a point where it emits light waves. Gases (xenon, I think) help sustain the wire until it breaks. This is when the light stops and needs to be replaced. (the tungsten also emits heat when lit) Incandescent lights have the full spectrum of colors. Fluorescent bulbs are filled with a gas and a bit of mercury. Electricity gives the ions in the gas energy, which is released in the form of light. This method sustains the bulb far longer than an incandescent lightbulb. Fluorescents release much less heat, making them more energy efficient. However, the spectrum of the fluorescent bulb is missing a few colors of the spectrum, which makes the spectrum look cool and incredibly weird.A fluorescent lamp or fluorescent tube is a gas-discharge lamp that uses electricity to excite mercury vapor. The excited mercury atoms produce short-wave ultraviolet light that then causes a phosphor coating on the inside of the bulb to fluoresce (glow), producing visible light.
What is man made plasma?
Man Made plasma can be found in Fluorescent and Neon Lights.
How long do fluorescent lights last?
Fluorescent light bulbs are extremely long-lasting. Most are designed to last over 10,000 hours. This comes out to approximately 416 days of continuous 24 hour usage. Even if used only 8 hours/day, the average fluorescent bulb should last over 3 years.
A neon light is more similar to an incandescent light or a fluorescent light explain how you know?
A neon light is much more similar to a fluorescent light. I know because I have a Ph.D. in physical chemistry, but I suspect you mean "justify your answer," so here goes. In a gas-discharge light (a neon light), a gas is ionized by an electric potential. Free electrons are then accelerated through the ionized gas. This causes the ions to transition into an excited electronic state. When the ion decays back to the ground state, energy of characteristic frequencies is emitted; the dominant frequencies depend on the gas, the voltage, and the pressure. This is why neon lights are orange-red: the dominant characteristic visible frequencies for neon gas are in the orange-red portion of the spectrum. (If you see a "neon" light that isn't orange-red, it's probably not really using neon gas.) A fluorescent light is exactly the same, except that the inside of the tube is coated with a fluorescent material. It absorbs the (high frequency) energy emitted by the gas discharge itself, and emits energy at a lower frequency (characteristic of the specific material). The gas in fluorescent lights is usually low-pressure mercury vapor, whose dominant emisison frequencies are in the ultraviolet. This is absorbed by the phosphor in the tube and re-emitted as a lower frequency (in the visible spectrum). Most fluorescent lights have a mixture of phosphors so that the emitted light appears "white" because it's actually a mix of different colors that kind of "average out" to white (this is like how the red, green, and blue phosphors in a CRT "blend" to appear white). To confuse matters even further, a lot of modern "neon" lights are actually just fluorescent lights with a colored dye or sleeve applied to the tube (if the tube, when off, appears white, colored, or "cloudy", it's probably a fluorescent light instead; if it's clear and looks empty, then it's pure gas-discharge). This allows for the production of "neon" lights of any color desired and also allows different sections of the tube to have different colors. An incandescent light glows because it's hot ("black body" radiation or "cavity" radiation). There's no characteristic frequency, though there is an emissions maximum which varies depending on temperature. If it's relatively cool ("red hot" is relatively cool as used here), it will appear a dull red; as it gets hotter it turns bright red, then orange, then yellow, then white, and ultimately starts to appear to have a bluish tinge as the emissions maximum shifts to shorter and shorter wavelengths.
What kind of lights are in hospitals?
Very bright fluorescent lights!!
What are lights names?
* Incandescent * Fluorescent * LED (light emitting diode)
Why do stores offices and schools use fluorescent lights instead of incandescent?
Incandescent lights are expensive to run (they give off a lot of heat was well as light), incandescent lights are much more efficient. However modern LED light bulbs are better (more efficient) than both incandescent and fluorescent lights so in the future you will see a change to the use of these.
Do fluorescent or incandescent bulbs offer the best bathroom lighting?
Incandescent lights work best for bathroom lighting. Fluorescent lights emit a cooler looking like, which does not bring out facial skin tone, which is detrimental when applying makeup.
Are fluorescent lights cheaper to run then incandescent globes?
Yes, they use less electricity.
What light is better a fluorescent light or incandescent light to grow a plant?
Definitely fluorescent. Incandescent lights are extremely inefficient and spend most of their energy producing heat rather than light. This is why an incandescent lightbulb gets so much hotter than a fluorescent one.
Which bulb last longer an incandescent light bulb or Compact fluorescent lights?
compact floresent
One office building contains only incandescent lights The building next door contains only fluorescent lights Predict which building has higher energy bills Explain your answer?
fluorescent because they use more energuy
Which light bulb uses more energy?
Incandescent and halogen light bulbs use more energy than compact fluorescent lights and LED lights. Fluorescent lamps with magnetic ballasts use more energy than fluorescent lamps with electronic ballasts.
Compact fluorescent lights are better for both our wallet and the environment but do they produce better light than the traditional incandescent bulbs?
Yes, the compact fluorescent light produce more light as compared to the same wattage of incandescent light, it is scientifically proved.
What is the difference between cCFL and CFL?
A CFL, or compact fluorescent lamp, is a type of fluorescent lamp intended to replace traditional incandescent lamps. Advantages of CFL's include lower power use, a longer rated life, and significantly lower greenhouse gas emission. However, these lights tend to have higher purchase prices than those of incandescent alternatives. A CCFL, or cold cathode fluorescent lamp, is any type of fluorescent lamp in which the cathode is not independently heated. Neon lights are common examples of CCFL's.
What type of lighting to use inside a home?
You can use incandescent, fluorescent or halogen lighting fixtures meant for indoor use inside a home. For example, you can purchase incandescent wall lights that are connected to a dimmer switch with incandescent lamping. Fluorescent lights might be in models of ceiling lights, chandeliers and pendant lights. Fluorescent lights are energy efficient lighting choices. Halogen lamps are used in some recessed lighting for indoor use. Floor lamps may also use halogen bulbs. Read carefully to see what type of indoor lighting can withstand damp settings such as the bathroom.
