Yes that's true fluorescent bulbs are better because it usess 75% less energy and works longer than a incandescent light bulb.
Yes...and no. It is true that power usage decreases with fluorescent balb usage. However, one must take into account that they pollute more (i.e. Mercury and other heavy metals).

∙ 14y agoBoth kinds come in different power ratings, but in general, the fluorescent light bulb will use less energy by a factor of 2-3, compared to an incandescent light bulb, for the same amount of light. Claims of a factor of 5 are sometimes made. Those are exaggerated, but it is still convenient to use fluorescent light bulbs.

Why is the plimsoll line so important in terms of density?
The plimsoll line shows how GAY boats are, and how scared the captain is of putting "too much freight" on the boatHere is a random bit of text:An incandescent light bulb, incandescent lamp or incandescent light globe is an electric light which produces light with a filamentwire heated to a high temperature by an electric current passing through it, until it glows (see Incandescence). The hot filament is protected from oxidation with a glass bulb that is filled with inert gas (or evacuated). In a halogen lamp, filament evaporation is prevented by a chemical process that redeposits metal vapor onto the filament, extending its life. The light bulb is supplied with electrical current by feed-through terminals or wires embedded in the glass. Most bulbs are used in a socket which provides mechanical support and electrical connections.Incandescent bulbs are manufactured in a wide range of sizes, light output, and voltage ratings, from 1.5 volts to about 300 volts. They require no external regulating equipment, have low manufacturing costs, and work equally well on either alternating current or direct current. As a result, the incandescent lamp is widely used in household and commercial lighting, for portable lighting such as table lamps, car headlamps, and flashlights, and for decorative and advertising lighting.Incandescent bulbs are much less efficient than most other types of lighting; most incandescent bulbs convert less than 5% of the energy they use into visible light[1](with the remaining energy being converted into heat). The luminous efficacy of a typical incandescent bulb is 16 lumens per watt, compared to the 60 lm/W of a compact fluorescent bulb. Some applications of the incandescent bulb deliberately use the heat generated by the filament. Such applications include incubators, brooding boxes for poultry, heat lights for reptile tanks,[2][3]infrared heating for industrial heating and drying processes, lava lamps, and the Easy-Bake Oven toy. Incandescent bulbs also have short lifetimes compared with other types of lighting; around 1000 hours for home light bulbs versus up to 10,000 hours for compact fluorescents and up to 100,000 hours for LED lamps.Because of their inefficiency, incandescent light bulbs are gradually being replaced in many applications by other types of electric lights, such as fluorescent lamps, compact fluorescent lamps (CFL), cold cathode fluorescent lamps (CCFL), high-intensity discharge lamps, and light-emitting diode lamps (LED). Some jurisdictions, such as the European Union, are in the process of phasing out the use of incandescent light bulbs.sincerely, Einstein

Why does an incandescent bulb of similar energy 60 watts versus 15 watts make water evaporate more quickly than a compact fluorescent lightbulb?
An incandescent bulb gives off more heat than a fluorescent bulb.
What is the main difference between an incandescent light bulb and compact fluorscent light bulb?
An incandescent bulb differs from a fluorescent based on how it produces light. "Incandescent" means producing light through heat, this is essentially how an incandescent bulb lights. As current travels to the tungsten filament, the filament heats and lights up as the tungsten filament begins to deteriorate and eventually fail. Fluorescent bulbs produce light when current excites gasses inside the glass envelope. As the gasses get excited they emit photons. Interestingly, the light produced by a fluorescent bulb does not fall along the visible spectrum until it passes through the white, phosphor coating on the inside of the bulb. And there you have it.
What is energy efficient device?
It's a device that can convert energy of one form into another efficiently. Like a lightbulb for example, an energy efficient one would use less electricity but still produce as much light as one that is less efficient. It's a measure of what you get out versus what you put in.

How much energy does a CFL light bulb save versus an incandescent bulb?
About 80%. An incandescent bulb produces 12 lumens per watt, (15 for halogen) while a CFL produces about 60 lumens per watt.

Can you put compact fluorscent lights into incandescent fixtures with no worries about harmonic distortion or heating of conductors?
CFL ARE GENERALLY CONSUME LESS THAN 50% VERSUS THE INCANDESCENT LAMP LUX COUNTERPART. YOU CAN USE WITHOUT WORRIES FOR IT WILL NOT CAUSE OVERHEATING DUE TO OVERLOAD AND INTERFERENCE PROVIDED SAME VOLTAGE RATING AND YOU CAN FIND WIDE VOLTAGE RANGE MODEL TO BEAT VOLTAGE FLUCTUATIONS. SOME MANUFACTURERS DESCRIBE CFL AS ENERGY EFFICIENT LAMPS.
Why are fluorescent light bulbs more energy efficient then halogen lamps?
Old-style fluorescent tube bulbs and the newer CFBs (compact fluorescent bulb) are considered more efficient for a number of reasons. First, they consume roughly 1/5 the energy of incandescent (ie, tungsten filament) bulbs for a comparable light output. A quick survey of the package labels tells that an average CFB is rated for 15 watts of electrical consumption, versus 60 to 75 for the average incandescent bulb. So, there is a savings in electricity, whether you choose to quantify that savings as monetary or environmental. Second, in addition to the decreased operational cost, fluorescent lights have a lifespan many times that of incandescent bulbs, which must be replaced more frequently. This translates to myriad efficiency gains; there is a financial incentive for their use, since over the long haul, they are less expensive to purchase and replace than incandescent bulbs. There is an even greater incentive for industrial and commercial consumers, since this reduced frequency in replacement translates directly into decreased maintenance and manpower costs. Take your average Wal-Mart or warehouse store -- if those thousands of bulbs were incandescent lighting, the store would have to maintain a small staff dedicated to the continuous replacement of its bulbs. Third, in addition to this obvious time and energy savings, there are more subtle efficiencies that can be found; fluorescent bulbs generate far less heat in operation than comparable incandescent bulbs -- in fact, many run completely cool to the touch. Compare this with the average incandescent bulb; although advances such as 'cool white' bulbs have decreased the heat of the incandescent bulb, all will burn a user instantly, as they generate a significant amount of heat. Since the bulk of the average electric bill (residential or commercial) is spent on air conditioning, this unwanted additional heat source is to be avoided, since it results in incrementally higher cooling bills. Even if the added heat is desirable (for example, in winter), this would still be a very inefficient means of heating. Fourth, any source of heat can be a cause of a fire. Reducing and eliminating unnecessary heat sources is good safety sense. Countless home fires have been caused by table lamps falling over, or random clothing items draped over lampshades. It's hard to question the inefficiency of everything one owns going up in smoke. Despite the many advantages of fluorescent lighting, many environmentalists have concerns about the toxic content of fluorescent bulbs, which contain Mercury. These bulbs should not be placed in ordinary residential waste collection, but should rather be recycled through a local hazardous materials collection program, which all American communities should have. On the point of Mercury toxicity, it can however be argued that the increased electrical demand of an incandescent bulb causes more Mercury to be released at the point of electrical production; trace amounts contained in coal burned to produce the electricity accumulate into more than is contained in the fluorescent bulb. Thus, simply because an incandescent bulb contains no Mercury, it isn't completely blameless. Its increased electrical consumption likely releases comparable quantities of Mercury as CFBs.
