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.

What is the name of those swirly light bulbs?
They are known as CFL bulbs. It stands for Compact Fluorescent Lamps.
How do energy efficient light bulbs work?
Light bulbs always use energy. Therefore to save energy they should be switched off. But certain types of bulb use much less energy than others: Incandescent: 10 lumens per watt Halogen: 13 lumens per watt Fluorescent: 50-60 lumens per watt (cheap to buy) LED: 50-70 lumens per watt (expensive to buy)
What are light bulbs that save energy called?
EcoSmart, ArmorLite, Philips, GE, and Sylvania all make a line of energy saving light bulbs. They all manufacture LEDs, CFLs, and halogen bulbs. All of these bulbs are comparable in performance and all of these products are energy savers.
What wattage halogen bulb will match a 100 watt incandescent?
Halogen bulbs are about 30% more efficient so a 70 watt halogen does the job.
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.
What is the name of those swirly light bulbs?
They are known as CFL bulbs. It stands for Compact Fluorescent Lamps.
Which Lighting will be the most energy efficient?
Compact fluorescent light bulbs are pretty energy efficient and are energy star rated.
What is the most energy efficient light bulb?
Light bulbs in order of the least to most energy efficient : incandescent, halogen, fluorescent, LED. For home owners, most reasonable is the CFL lightbulb, which is cheaper and longer lasting than the LED.
What is the difference between halogen and incandescent bulbs?
Halogen light bulbs are what has been around for a very long time. Incandescent bulbs are new and are more energy efficient.
Which is more efficient the fluorescent bulbs or the incandecent bulbs?
Fluorescent bulb is the more efficient one as compared to incandescent bulbs.
Are there energy efficient table lamps?
Energy efficient table lamps are available in many online shops such as LampPlus and YLighting. Lamps can even be made energy efficient by changing the light bulbs to fluorescent spiral bulbs.
What type of light is 20w energy saving bulb Halogen Indandecent neon fluorescent etc please help?
The energy saving light-bulbs are usually fluorescent. Neon is a type of fluorescent light bulb.
How many times do you need to replace energy efficient fluorescent light bulbs?
comparing to the traditional light bulbs energy efficient fluorescent light bulbs uses 25% to 75% energy and saves money also and it lasts up to 3 to 25 times long so there is no need to replace energy efficient fluorescent light bulbs often.
Is compact fluorescent light the best energy saving bulb?
No, the most energy efficient bulbs are LED (Light Emitting Diode) light bulbs.
Fluorescent light bulbs are considered more efficient because they they?
Lose less energy as heat.
Why are LED bulbs considered to be better at saving energy than compact fluorescent ones?
LED bulbs, or Light Emitting Diode bulbs are far more efficient at turning energy into light than fluorescent bulbs. They are the most energy efficient bulbs available today and last much longer than any other bulbs. Although very expensive, the price is expected to come down over time.
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.
