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.
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 is the difference between led and halogen lights?
Halogen light glows and LED is dull.
What kind of lights are in hospitals?
Very bright fluorescent lights!!
Fluorescent light more energy efficient than incandescent light?
Yes, fluorescent lights are more energy-efficient than incandescent lights. Fluorescent lights use 25-35% of the energy that incandescent lights use to produce the same amount of light, making them more cost-effective and environmentally friendly.
What light is better a fluorescent light or incandescent light to grow a plant?
Fluorescent lights are better than incandescent lights for growing plants because they emit more of the necessary light spectrum for photosynthesis. Incandescent lights produce more heat and less usable light for plants, making them less efficient for plant growth.
Why do stores offices and schools use fluorescent lights instead of incandescent?
Fluorescent lights are more energy efficient than incandescent lights, saving on electricity costs over time. They also have a longer lifespan, reducing the frequency of bulb replacements. In large spaces like stores, offices, and schools, the cost and maintenance benefits of fluorescent lights make them a practical choice.
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?
The building with incandescent lights will likely have higher energy bills because incandescent lights are less energy-efficient than fluorescent lights. Fluorescent lights use less energy to produce the same amount of light, making them more cost-effective in the long run.
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.
What are lights names?
There are various types of lights, including incandescent, fluorescent, LED, and halogen lights. Each type serves different purposes and has distinct characteristics like energy efficiency, color temperature, and lifespan.
Are fluorescent lights cheaper to run then incandescent globes?
Yes, they use less electricity.
Which bulb last longer an incandescent light bulb or Compact fluorescent lights?
compact floresent
Do fluorescent lights produce heat?
Yes, fluorescent lights produce some heat when they are on, but significantly less compared to incandescent bulbs. The majority of the energy consumed by fluorescent lights is converted into visible light, making them more energy-efficient.
Why do plants need incandescent lights?
Plants need incandescent lights for photosynthesis. Incandescent lights emit a broad spectrum of light that includes red wavelengths needed for photosynthesis. However, incandescent lights are not very energy-efficient and can generate excess heat, which may be a problem for indoor plants.
What are cfl lights?
CFL lights are compact fluorescent lights that use a fluorescent tube to produce light. They are more energy-efficient than traditional incandescent bulbs and last longer. CFL lights are a popular choice for residential and commercial lighting.
