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.
They are known as CFL bulbs. It stands for Compact Fluorescent Lamps.
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)
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.
Halogen bulbs are about 30% more efficient so a 70 watt halogen does the job.
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.
They are known as CFL bulbs. It stands for Compact Fluorescent Lamps.
Incandescent produces about 10 lumens of light per watt of electricity Halogen produces about 13 lumens per watt Fluorescent and CFL produce about 50 lumens per watt So Fluorescent is the most efficient.
Some energy-efficient options for household light bulbs include LED bulbs, compact fluorescent lamps (CFLs), and halogen incandescent bulbs. These bulbs use less energy and last longer than traditional incandescent bulbs, helping to reduce electricity costs and environmental impact.
The main difference between T12 and T8 fluorescent light bulbs is their size and energy efficiency. T12 bulbs are larger and less energy efficient compared to T8 bulbs, which are smaller and more energy efficient.
Compact fluorescent light bulbs are pretty energy efficient and are energy star rated.
Halogen light bulbs are what has been around for a very long time. Incandescent bulbs are new and are more energy efficient.
Yes, it is possible to replace fluorescent bulbs with LED bulbs. LED bulbs are energy-efficient and have a longer lifespan than fluorescent bulbs, making them a popular choice for lighting upgrades.
Fluorescent bulb is the more efficient one as compared to incandescent bulbs.
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.
The energy saving light-bulbs are usually fluorescent. Neon is a type of fluorescent light bulb.
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.
Halogen light bulbs are more energy-efficient and have a longer lifespan compared to incandescent light bulbs. Halogen bulbs use less energy to produce the same amount of light as incandescent bulbs, and they also last longer before needing to be replaced.
