What type of light is a 20 watt energy saving bulb Halogen Incandescent neon or fluorescent?
A 20 watt incandesent bulb is dim. For a medium sized room you need 100 watts.
A 20 watt halogen bulb is brighter but still quite dim. These are marketed as low-energy but they are not. For a medium sized room you need 80 watts.
A 20 watt fluorescent bulb can light a medium sized room quite brightly. This is a genuine low energy bulb.
The energy saving light-bulbs are usually fluorescent. Neon is a type of fluorescent light bulb. Read More
You save about 80% of the energy by using fluorescent, as compared to incandescent. Read More
A compact fluorescent lamp (CFL), also called compact fluorescent light, energy-saving light, and compact fluorescent tube, is a fluorescent lamp designed to replace an incandescent lamp; some types fit into light fixtures formerly used for incandescent lamps. The lamps use a tube which is curved or folded to fit into the space of an incandescent bulb, and a compact electronic ballast in the base of the lamp. Read More
Fluorescent lighting is much more energy efficient than incandescent lamps, usually by as much as 60 to 80%. That also translates into a corresponding energy savings. I don't recall the exact figure off hand, but the light output from a fluorescent lamp is about three times it's rating. For instance, a 40 watt fluorescent puts out the equivalent light of a 120 watt incandescent bulb. Read More
It varies, depending on the specific model, but an energy-saving (fluorescent) light bulb should save at least half the energy, for the same luminosity, compared to the old-fashioned incandescent light bulbs. The incandescent light bulbs ought to be outlawed, except for specific purposes where the heat they generate is actually needed. Read More
Typical halogen bulbs that screw into normal light sockets can be replaced with energy saving bulbs that operate at the same voltage. Read More
There are many ways to save energy, for example, light emitting diodes (LEDs) use much less energy than incandescent lighting or even fluorescent lighting. Whether you do or do not eat lunch seems to be irrelevant to the issue of saving energy. Read More
Lumens measures how bright it is, watts measures how much electric power it uses up. An old-type incandescent bulb produces about 10 lumens per watt. A halogen produce about 13 lumens per watt. A fluorescent (energy saving) bulb produces about 50 lumens per watt. LEDs produce somewhere around the same as a fluorescent. Read More
In the most general terms, you can do two things. (1) Turn off appliances you don't need. For example, turn off lights and television when nobody is using them. (2) Get energy-saving versions of some equipment. For example, if you still have incandescent light-bulbs, replace them with the more modern (and energy-saving) fluorescent ones. Read More

A compact fluorescent lamp or CFL has the advantage of consuming less power. It works in the same way as a fluorescent tube light however it is made in a much more compact shape. This means CFLs can be used to replace ordinary light bulbs which have incandescent filaments. If you replace your ordinary light bulbs with CFLs they will use only 20% (one fifth) of the energy to give you the same amount of… Read More
Take a look here, this explains all the types of light bulbs. Incandescent: A majority of American households use incandescent light bulbs in their home. These bulbs are inexpensive and produce a warm light that is suitable for basic household- or appliance-use. The average incandescent bulb lasts around 1,000 hours. Halogen: Halogen bulbs are similar to incandescent bulbs, though they are more energy-efficient and last longer. Halogen bulbs produce a bright white light. They become… Read More

The question should be put the other way round, the energy rating (wattage) of the bulb affects its size. This is for conventional incandescent gas filled bulbs. Other types such as halogen bulbs have different sizes, but again the larger the wattage the larger the bulb, and the same for more modern energy saving bulbs. IT MAKES NO SENCE TO ME!!!! Read More
Compared with an incandescent bulb, a fluorescent tube uses about 80% less electrical power for the same amount of brightness. A 150W incandescent can be replaced by a 30W tube. If it's on for 200 hours a month the saving is 200 x 120 watt-hours or 24 kilowatt-hours, saving about £3.60. Read More
No, the most energy efficient bulbs are LED (Light Emitting Diode) light bulbs. Read More
A CFL is a type of fluorescent lamp that is roughly the size of a traditional incandescent light bulb. In many cases the CFL is designed to screw into a standard medium screw socket and replace an incandescent bulb. A CFL has a higher initial expense than an incandescent bulb, but uses less electrical power and lasts far longer. CFLs are available in many color temperatures. See the color temperature link below for a table… Read More
Not necessarily. They can be brighter, or less bright. Both the energy saving light bulbs and the old-fasioned incandescent light bulbs come in different powers. Read More
Halogen light bulbs are more efficient on energy and last twice as long as a regular light bulb thus saving you money. After researching several websites on energy it is stated that a regular light bulb costs $9.49 for 1460 hours of use whereas a halogen light for the same amount of hours costs $8.76. Read More
No light bulbs actually save energy, they use it to produce light. However energy efficient bulbs use less energy than the ordinary incandescent type. To my mind describing them as energy saving is wrong, they should be described as "lower energy" bulbs. Read More
About 50-60, which is 4-5 times better than incandescent bulbs. Read More
It is not a waste of money if you need the light but that being said, the higher the wattage usually reflects in a higher cost to the consumer. To answer this question the voltage and current of each device should be stated so that calculations could be made. An energy saving fluorescent is driven by an internal ballast and it is the ballast input current that is needed. Read More
Neodymium is used in color televisions. It is a rare chemical that can be found in televisions as well as energy saving lamps and fluorescent lamps. Read More
Very little, but it is noticeable, with a bright light in a small room. A light bulb puts out between 9 watts (energy-saving fluorescent light bulb) to approximately 100 watts (bright incandescent light bulb). Your average bar-heater, for comparison, puts out about between 1200-2400 watts. Read More
Incandescent bulbs: 10 lumens per watt Halogens: 13 lumens per watt CFLs: 50 lumens per watt A useful bulb to light a small room is 600 lumens, so that would need a 60-watt incandescent, or a 45-watt halogen, or a 12-watt CFL energy-saving bulb. The best CFL bulbs are the spiral ones. Read More
The wattage rating of a bulb is in direct relation to its energy usage per unit time. A 100 watt bulb consumes twice as much energy as a 50 watt bulb over the same period. Keep in mind that the latest generation of energy saving bulbs (Compact Fluorescent Lamp) can be labeled both how much energy they actually consume, and also by how much light they produce as compared to an incandescent bulb. For instance… Read More
A Compact Fluorescent Lamp (CFL) is type of energy-saving bulb made from a small glass tube which is filled with mercury vapour. It has a phosphorescent coating on the inside of the tube which glows when electricity is passed through the mercury vapour causing it to emit ultraviolet light. This is the same mechanism as a standard fluorescent tube light, the only difference in a CFL is that it has a smaller size and is… Read More

There are two different technologies, fluorescent, and LEDs. Fluorescent light bulbs are more common; LEDs are still too expensive for mainstream use. +++ LED lamps' prices are now very competitive, certainly where I live, and make up for the unit price difference in reduced electricity consumption for a given light output. I have a mixture of incandescent, CF and LED lamps in my home, and slowly going over to LED as the existing lamps expire. Read More
Energy saving lamp LED or CFL bulbs are being used in cars and even in heavy vehicles are they comparable with the old incandescent bulbs in terms of luminance?
LED, CFL and incandescent, when compared in terms of luminance, LED beats both of them. The range of difference between LED and incandescent are very big, whereas CFL comes in between them. Read More
An energy saving light bulb is simply a fluorescent light-bulb in a small housing with a built in starter . The gas used for it will be the same as a standard strip-light which is a tube filled with low pressure mercuric oxide and an inert gas like Argon Neon or krypton. Read More
I have a car showroom I use a lot of lighting in my showroom but due to heavy electricity bill and environmental consciousness I want to know about how to save electricity?
If you are using the ordinary incandescent bulb then you should firstly replace all your lights with energy saving bulbs like CFL, LED and Halogen. They saves a large amount of energy and electricity bills and are also eco-friendly. But when you buy these bulbs better look for Energy Star rated lights because they saves energy more effectively. dont keep any electric equipments in standby mode, they also consumes energy.

These days I have noticed that lots of manufacturer is advertising about their energy saving lamps how these lamps works is there any special circuit inbuilt through which they can saves energy?
In traditional incandescent bulbs, tungsten is used as filament which draws heavy energy to illuminate, while in modern energy saving lamps we use CFL or LED which draw little amount of energy for the same luminance, CLFs are associated with a compact electronic ballast in the base of the lamp. Read More
In general an energy saving bulb will be much more expensive to buy than an incandescent bulb, but much cheaper to operate as it uses only a fraction of the electricity. Ideally the money saved in use more than offsets the purchase price making an energy saving bulb cheaper over its entire lifetime, but in reality this may not be the case. Read More
The fluorescent bulbs typically use between 1/2 and 1/3 as much electricity as a normal light-bulb, for the same luminosity. Read More
First of all, a light bulb of any sort is not an energy saving device. It is an energy consumption device, and some types simply consume less than others. A filament light bulb, also known as an incandescent bulb, has a thin filament of high temperature wire that gets hot when electricity flows through it. In fact it becomes so hot it emits light (incandescence), so the light is produced as a by product of… Read More
Depends which kind of lightbulb. Incandescent light bulbs are not filled with gas. Energy saving lightbulbs may be filled with a range of gases. These include Neon, Phosphorus and Fluorine. Read More
You can reduce the usage of fossil fuels by developing alternative energies. Some options are solar energy, wind energy, hydraulic energy, geothermal energy, and several others more. While some progress has been made, a lot has to be done yet - we depend way too much on fossil fuels. Another thing that should be done is to reduce energy usage in general. For a start, see if you have the old-fashioned incandescent bulbs, and change… Read More

In an energy saving light bulb, the electricity passes through a gas which causes it to emit ultraviolet rays. When these rays pass through the flourescent coating, the become visible, white light. Actually an energy saving light bulb is simply any light bulb that uses significantly less electrical energy than an incandescent light bulb that produces the same amount of visible light energy. There are several technologies that can do this, two that have made… Read More
Energy-saving lamps, such as normal and compact fluorescents, use more of the energy they consume to produce light rather than heat. An incandescent light converts electricity to heat and light is simply a by-product of the heat. Fluorescent bulbs still have incandescent filaments, but they are used to emit the electrons that run the length of the tube colliding with the vapourised mercury and producing light. Mainly because they run "cool", a fluorescent lamp uses… Read More
Today, family, shopping malls, hotels and other places are the subject to use fluorescent lamps and energy-saving lamps to illuminate, , now, take fluorescent lamps and energy-saving lamps for example, let's look at the specific effect of LED lighting energy .
