10 Energy Efficient Light Bulbs

Light bulbs have long been an essential household item, with a variety of different types and brightness levels available, which can suit all kinds of spaces. Energy efficient light bulbs have become increasingly widespread due to their greater energy efficiency than the traditional incandescent bulbs.

Energy efficient light bulbs also last for much longer than incandescent bulbs, and can also be more cost effective, particularly for large buildings. Energy efficient light bulbs are available in a range of different styles, and a wide variety of all kinds of light bulb and other lighting items can be found on eBay.

Types of Energy Efficient Light Bulb

Energy efficient light bulbs function differently to incandescent light bulbs, which have been in use for much longer. In some parts of the world, energy efficient light bulbs have come to replace incandescent bulbs as the most common type used, with some areas even limiting the usage of incandescent light bulbs via legislation.

· Incandescent light bulbs work through the use of sending an electrical current through a filament suspended in the glass bulb, which is filled with a gas such as argon.

·  It is the current running through the filament, which generates light, as well as an enormous amount of heat. Incandescent bulbs can light up much faster than some energy efficient types, but are less efficient and do not last as long.

· Energy efficient bulbs are available in two main types, LED and CFL.

CFL Light Bulbs

CFL light bulbs, or compact fluorescent lamps, are one of the most recognisable and widely available types of energy saving light bulb.

· CFL light bulbs are made up of carefully folded tubes, which are coated inside with phosphor and filled with gas. When the gas is electrified, it emits ultraviolet rays that cause the phosphor to illuminate.

· These bulbs can take some time to reach their full brightness, as the phosphor can take some time to fully illuminate.

· CFL light bulbs are also able to produce a greater amount of light from less wattage, and also waste less energy in heat.

· A variety of different styles of CFL bulbs are available.

LED Light Bulbs

Another type of energy efficient light bulb is an LED, or light emitting diode.

· Light emitting diodes are very small light sources, which generate light from an electrical current.

· LEDs can be found in a wide range of colours, and different strengths of light.

· Light emitting diodes are small, long lasting and require little power.

· LED bulbs are not as effective for use with dimmer switches as other types of light bulb.

· A variety of different types of LED lights are available, and the most popular styles include spotlights and strip lights.

Energy Efficient Light Bulbs

There are a number of different widely popular types of energy efficient light bulbs.

Spiral

The spiral light bulb, also known as the integrated helical bulb, is one of the most common types of CFL light bulb. This type of bulb has the tubing shaped into that of a spiral, and generally takes the role of a standard bulb, available in a variety of different light levels. This type of bulb is particularly popular in North America. 

Tubular

Another popular type of energy efficient bulb is the tubular design, a widely available style of CFL light bulb. Like the spiral bulb, these light bulbs can be found offering a variety of different light levels. These CFL bulbs can sometimes be longer than the spiral bulbs, and may not look right in some types of lamp. This is the style of CFL light bulb, which is most popular across Europe.

Spotlight

A popular type of light bulb is the spotlight. Spotlights are smaller lights and typically direct the light onto a specific area. Many spotlights can also be positioned in order to differently illuminate the room. Both CFL and LED light bulbs are available in spotlight form, and are a popular choice for use with dimmer switches.

Candle

A popular type of light bulb is the candle bulb. These bulbs are often designed to look similar to the flame of a candle, and generally give out a lower level of light than other types of light bulb. These light bulbs can be a great choice for setting a mood in a room, and are available as both CFL and LED light bulbs.

Strip

Strip bulbs are designed for use in strip lights, which are often designed to be long and thin. Strip bulbs are available in a range of different wattages, and can feature both CFL and LED light bulbs. Flexible strip lights are also available, often featuring coloured LEDs, and are a good choice for use in decorative lighting.

Corn

An unusual type of LED light bulb with a unique appearance is a corn light bulb, and is called so because it resembles a cob of corn, the corn light can be useful for a wide range of applications, and projects light in all directions.

Globe

Another simple type of light bulb is the spherical globe bulb. These are suitable for various different types of lamp, and can be found with a range of different wattages.

3 Way

CFL bulbs can also be found in 3 way models. 3 way light bulbs can shine at different settings of brightness, generally high, medium and low.

Flicker

Flicker bulbs are designed to produce a flickering light reminiscent of that produced by the flame of a lit candle. Most often made with an LED, these bulbs are an ideal choice for decoration, and produce a low level of light.

Flame

In addition to flicker light bulbs, flame bulbs are also available. Similar to the flicker bulbs, these light bulbs also aim to reproduce the flicker of candlelight, but in addition are also often shaped like a flame, and frequently coloured red or orange to add to the effect.

How to Buy an Energy Efficient Light Bulb on eBay

A wide range of energy efficient light bulbs featuring a range of different styles and types can be found on eBay.

· The full listing of available light bulbs can be found through the Home & Garden portal, in the Light Bulbs section of the Lighting, Fans category.

· Light bulbs can be arranged by categories, such as price, product type, colour and item location.

· It is also possible to sort bulbs by style, making it easy to find a bulb with a specific style, such as romantic, nautical or vintage.

· Don't forget to look out for any deals on light bulbs that may be available in the Home & Lifestyle section.

Conclusion

Energy efficient light bulbs can generate more light per watt than traditional incandescent bulbs, and are becoming an increasingly popular choice. Energy efficient bulbs are available in two main types, CFL and LED bulbs. CFL, or compact fluorescent lamps, are made out of folded tubes and filled with gas.

When subjected to an electric current, the gas causes the phosphor that the tubes are coated with to illuminate. LEDs generate light from an electric current. Energy efficient bulbs can be found to suit any room or lamp, including spiral, spotlight and flicker bulbs. A wide range of light bulbs can be found on eBay.
