In the advent of global warming and the rise in the cost of energy, people are looking for ways to save the planet and save money. If you intend to reduce either carbon footprint or your monthly electricity bill, compact fluorescent bulbs are a good choice to meet your needs. Compact fluorescent bulbs have several advantages over conventional light bulbs. Their long life and low operating costs make of these compact fluorescent bulbs an ideal option for private dwellings, street lighting, car parks as well as businesses.

Compact fluorescent bulbs contain small amounts of mercury at the centre, which burns to release gas in the fluorescent bulbs. The result is a bright white light and less waste of energy. Instead, the bulk of the energy is converted into heat, like a glowing, which then creates light. This in turn means more light per watt of compact fluorescent bulbs as compared to other bulbs and lamps.

Prior to the invention of the compact fluorescent bulbs, if you wanted to have fluorescent light bulbs in your house, you would have needed special arrangements for them. But now the compact fluorescent bulbs can be screwed into any socket for incandescent lamps.

However, the compact fluorescent bulbs bear one major disadvantage. Because of the presence of mercury, wasted compact fluorescent bulbs must be managed carefully. Since it is well known that mercury can affect human health, these bulbs must be directed to recycling plants. Compact fluorescent bulbs should not be thrown at random or dumped because this could lead to leakage of mercury, which may be washed away into domestic water.

It is also essential that the compact fluorescent bulbs are allowed to cool down at regular intervals between the cycles of heating and lighting. It might be a good idea, for instance, to have another source of light in the same room where the compact fluorescent bulb is being be used so as to alternate between the two. A halogen lamp, for instance, should be considered as alternate source of light. This approach will ensure the best in energy efficiency and lifespan of the compact fluorescent bulbs. On the other hand, if for instance you are the owner of a factory where the amount of lighting is important, then you should not go for halogen lamps, which can heat up to very high levels when turned on. In such cases, compact fluorescent bulbs are the best options.

Of course, you also need to consider other less technical aspects such as finish, color and style when making your choice of lighting bulbs. Compact fluorescent bulbs may not always be producing the desired effect. If you are not sure these aspects, you can always seek expert advice. With regard to installation, you can just follow the instructions on the packaging of the compact fluorescent bulbs and this can become as easy as child’s play. The guidelines should be fairly easy to follow and installation should not be much of a hassle.

Energy Saving Lamps

With more people interested in buying eco-friendly products each day; energy saving lamps are fast replacing incandescent bulbs. Even though they cost more than the normal bulbs, you can save significantly on your energy bill by using energy saving lamps. Here are some of the benefits associated with this modern marvel of technology that is lighting up an increasing number of homes around the world each day.

Compact fluorescent lamp (CFL) or energy saving lamps as they are popularly called use improved phosphor formulations to emit light that is similar in color to the standard incandescent lamps. Each unit can save as much as $30 over its usable life and significantly lowers the amount of green house gas emission. Most energy saving lamps are designed to replace their incandescent counterparts and can easily fit into existing light fixtures. They also have a longer rated life span.

An energy saving lamp comprises of two parts the gas filled tube on top and the magnetic ballast at the bottom. The electric current flows through the magnetic ballast charging the mercury vapor inside the tube causing an emission of ultraviolet light. This in turn is turned to visible light due to the phosphor coating emitted by the ultra violet light.

There two versions of energy saving lamps available in the market are:

Integrated: They comprise of a gas filled tube and a magnetic ballast put together in a bayonet or Edison screw fitting. They can easily be used to replace the incandescent lamps.

Non Integrated: This type of energy saving lamp has a permanent magnetic ballast but the bulb can be replaced. The ballast is placed in the fixtures and the bulb can be easily replaces after it has outlived its productive life. This version is more sophisticated and expensive than the integrated type.

Some of the advantages:

Energy Efficiency: Energy saving lamps need a significantly lower amount of energy to supply the same amount of light as an incandescent bulb. Since electricity is mostly produced by burning fossil fuel, this can equate to a massive reduction in the emission of green house gases and pollutants. Also since most of the energy saving lamps use lower voltage you can use more bulbs without your energy bill going through the roof.

Temperature: Most Incandescent lamps produce a lot of heat due to high energy consumption. But energy saving lamps generate considerably less heat due to the low voltage requirement. So they are ideal for settings that require light sources that emit less heat, such as near plants or paintings. So you can light up every part of your home without being concerned about the damage that the heat may cause.

Life Span: Since the bulbs have a significantly longer life span than the incandescent versions you will be buying fewer bulbs and wont have to go through the hassle of changing the bulbs as often as you normally do.

Designs: Energy saving lamps are available in a range of designs to suit all types of light fixtures so the possibilities are endless. You can use them in any room of your house and even within the floor for displays. They are small enough to be neatly concealed in the ceiling yet provide the same brightness of an incandescent lamp.

So if you haven’t switched over to energy saving lamps as yet, this is certainly a good time to buy a few

Compact Fluorescent Bulbs (CFL): Save Energy In Your Home And Benefit The Environment

For the last couple of years compact fluorescent bulbs have been very popular in the lighting industry. And there is a reason for this popularity; there are several benefits associated with using compact fluorescent bulbs. The primary advantage is of course the reduced pollution caused due to these bulbs since they consume less electricity than the conventional incandescent bulbs.

A Compact fluorescent bulb or energy saving light as it is commonly called is a type of fluorescent tube. They are designed to give the same amount of light as an incandescent bulb of the same voltage. They can save almost $30 over their useful life and emission of green house gases is reduced by 2000 times its weight. However, they do cost significantly more than the normal incandescent bulbs yet the power saving benefits of the compact fluorescent bulbs more than makes up for the high price.

The assembly of a compact fluorescent bulb consists of magnetic ballast and a tube coated with phosphor and filled with mercury vapor. The electrical current that passes through the magnetic ballast flows through the mercury vapor causing the emission of ultra violet light. This light in turn excites the phosphor coating and a visible light is emitted.

Most compact fluorescent bulbs are designed to fit into existing light fixtures and can easily replace the incandescent bulbs.

Also, once the tungsten filament in the normal incandescent bulb gives way they have to be discarded but compact fluorescent bulbs are available in two varieties the integrated compact fluorescent bulbs and the non- integrated versions.

In the integrated compact fluorescent bulbs the electronic ballast with the gas filled tube with a bayonet fitting or the Edison crew is a single unit. These units have to be replaced after their useful life is up.

But the non-integrated compact fluorescent bulbs have separate ballasts which are permanently installed. These are magnetic ballasts which are placed in the light fixture while the replaceable bulb houses the starter. The magnetic ballasts are larger and last longer than the integrated compact fluorescent bulbs. The non- integrated versions are more sophisticated and also more expensive than the integrated compact fluorescent bulbs.

Compact fluorescent bulbs are available for alternating current and for direct current.

The lifespan of a compact fluorescent bulb is 9 to 15 times more than the normal incandescent bulbs. They use between one fifth and one third of the power needed to light up an incandescent bulb.

Since the operating temperature of compact fluorescent bulbs is very low, they can also be used in places that require low temperature such as near paintings and sculptures that may get damaged due to the high temperature of incandescent bulbs.

A compact fluorescent bulb appears brighter than the incandescent bulbs. An energy saving lamp is 17- 21% efficient at converting electrical power to radiant power. In terms of the luminosity, a compact fluorescent bulb produces 60- 72 lumens per watt while an incandescent bulb can just do 8 to 17 lumens per watt.

So even though compact fluorescent lamps cost more buying them is not only good for the environment but also for your pocket.
