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 are incandescent bulbs?
An incandescent light bulb is your common household bulb. It is best identified by the presence of a filament (the thin piece of wire in the center of the glass bulb that glows when turned on.) The incandescent bulb's interior space is a vacuum (all the air is removed) so that the filament doesn't burn up. It produces a warm, slightly gold/yellow light. A "florescent" bulb, on the other hand, has no filament. It works by electrically exiting gas in a long tube creating a cool white light with almost the same color as the sun.
10 man-made sources of light?
1. Incandescent light bulb 2. Halogen light bulb 3. Compact fluorescent light bulb 4. Light emitting diode (LED) 5. Mercury vapor light bulb 6. Neon light 7. High intensity discharge lamps 8. Carbon arc lamp 9. laser 10. kerosene lamp
How many types of light bulbs are there?
352 There are six different types of light bulbs invented as of December 27, 2012. They include the incandescent light bulb, the halogen light bulb, the fluorescent light bulb, the high-density discharge lamps, LEDs, and sodium lamps.
How are CFL light bulbs better than regular light bulbs?
A CFL uses 65% less energy and can reduce your power bill as well.A longer answerSince major improvements in the design of Compact Fluorescent Lamps (CFLs) from 1990 onwards, by using a CFL light bulb 80% energy of the energy can be saved compared to the energy that is needed to produce a given amount of artificial light using conventional incandescent filament bulbs.In other words, to produce the same amount of visible light, a modern CFL uses only 1/5 (one fifth) of the power that an incandescent filament bulb uses.For example, a 20 watt CFL bulb produces similar light to a 100 watt incandescent filament bulb and a 30 watt CFL matches the light output of a 150 watt incandescent filament bulb.CFLs also have a much longer useful life-span, thus avoiding the need to change them as often as incandescent light bulbs.Another opinionThere are issues with the additional power used to manufacture CFL bulbs and the toxic chemicals inside these units.But, whilst they certainly do save energy for the end user, their drawbacks are that they probably use more energy overall and their manufacture causes more pollution.
Can you use an incandescent light bulb in a full spectrum lamp?
no
A typical incandescent light bulb produces?
A continuous Spectrum
A typical incandescent light bulb produces what?
A continuous Spectrum
How is a light bulb better for growing plants then a fluorescent?
The light spectrum from an incandescent (a bulb) is closer to the spectrum of the sun than what comes from a fluorescent.
Why does an incandescent light bulb produce a continuous spectrum that seems to favor red?
Actually the peak of the radiation from an incandescent light bulb is in the near infrared, not the visible spectrum. The visible light that you see is the falling upper sideband of this: very strong in the red and declining until it is weak in the blue and violet end with a very small amount of radiation in the ultraviolet. The lower sideband extends across the infrared and into the far infrared. Well under a third of the emitted electromagnetic radiation of an incandescent light bulb is visible light, most is infrared.
What kind of light bulb gives off the most heat?
Incandescent bulbs produce the most heat for a given amount of light; fluorescent lights produce much less heat, and LED produces the least.
How do you produce light bulbs in CO2?
You do not. CO2 has nothing to do with the creation of a light bulb. A typical incandescent bulb has a vacuum inside. No light bulb uses CO2.
Does a 25 watt light bulb draw more current than a 60 watt light bulb?
No, a higher wattage INCANDESCENT light bulb uses more current than a lower wattage INCANDESCENT light bulb. Some CF and LED bulbs are rated by the amount of light that an incandescent bulb would produce, but they are also rated by the wattage that they use.
What is the wave length of a 25 watt incandescent light bulb?
Since white light is emitted from an incandescent bulb, it contains all wavelengths in the visible light spectrum between 400 to 700nm. It also emits wavelengths in the infrared region.
As well as light what else does a light bulb produce?
It kinda depends on what kind of bulb incandescent lights use filaments and emit heat, for example
Do CF light bulbs produce as much heat as incandescent bulbs?
No, compact fluorescent bulbs run much cooler that an incandescent bulb. A CF bulb can be unscrewed when the lamp is on whereas an incandescent will give you a bad burn if this is tried.
What is incandescent light bulb?
An incandescent light bulb, incandescent lamp or incandescent light globe is an electric light which produces light with a wire filament heated to a high temperature by an electric current passing through it, until it glows.
