Energy Saving Bulbs That Use LED Technology

Using Bulbs that use LED Technology is the most Energy-Efficient way of lighting up a place. LED was first introduced as replacements for their more fragile versions in electronic appliances like the radio, television, etc. and not as a source of light. However with the advancements in LED technology, LED Bulbs were soon invented and begun to be used for lighting purposes.

LED (Light Emitting Diode): LEDs (Light Emitting Diodes) are semiconductors used as light sources. The technology which comes into play here is that when a flowing electron meets a hole and falls into a lower energy level, resulting in the instability of energy levels. It releases energy in the form of photons in order to regain the balance. As a result of this release of energy, light is emitted by the LED.

However, it was not until the sapphire technology was used that LED Bulbs began to be used as sources to light up a place. LED Bulbs save even more energy than the CFL Bulbs. For the same amount of light produced, LED Bulbs use only 6-8 watts of energy while the CFL Bulbs use 13-15watts. Even in the matters of longevity, the LED Bulbs outrun the CFL Bulbs. Some studies conducted in this matter have shown that a LED can last up to 7 years even if kept on non-stop for the entire period.

Reasons For Less Energy Consumption
The reason why Fluorescent Bulbs and LED Bulbs consume less energy than an Incandescent Bulb is that while the filament of an Incandescent Bulb loses much energy in the form of heat, LED and Fluorescent Bulbs convert electrical energy into light more efficiently. The reason why the LED Bulbs outperform even the Fluorescent Bulbs or CFL Bulbs in Energy-Efficiency is that while the CFL Bulbs radiate light in all directions, thereby losing energy, LED Bulbs direct the light towards the target areas.

Thus, even though the LED Bulbs cost way higher than the CFL Bulbs, LED Bulbs can prove more efficient in the long run by saving more energy. The price of LED Bulbs would come down once the high-cost sapphire technology can be replaced with silicon wafer technology.

Even with the present technology, low cost LED Bulbs can be bought online from LedLightDepot at www.ledlightdepot.co.uk. LedLightDepot offers advanced LED lighting options for domestic and industrial purposes.

CFL And LED Energy-Efficient Bulbs

Continuous advancements in the technologies of appliances around us keep updating the store-shelves with better versions which are more efficient in matters of performance and consumption of energy. It was only in the 1920s that the Incandescent or Filament Bulb had been introduced and now we hardly find any of them in use today. Electrical Lighting of households and exteriors are now primarily done by CFL and LED Bulbs.

CFL Bulbs: CFL Bulbs or Compact Fluorescent Lamp Bulbs use phosphors which provide a warm and gentle light. The prototype of the modern CFL Bulbs was invented by Peter Cooper Hewitt in 1890. The photographic studios and industries made use of these prototypes. However, modifications were made and many designs later, the modern CFL were made available in the shops.

LED Bulbs: LED Bulbs or Light Emitting Diodes is a semi-conductor light source, initially used in sign-boards and other displays. However, technological advancements have ensured that the LED Bulbs are also being used for conventional lighting purposes. Apart from the conventional semiconductor diodes, LED Bulbs also use organic LEDs (OLED) and polymer LEDs (PLED). The LED bulbs are also gaining popularity in use.

Both CFL and LED Bulbs enjoy distinct advantages over the outdated Incandescent Bulbs. The most important advantage is the significantly lower consumption of energy. In fact, the Energy-Efficiency of CFL and LED Bulbs is so high that Sri Lanka has banned the import of Incandescent Bulbs and countries like Australia are on the way to impose a total ban on Incandescent Bulbs. Even without the ban, the Incandescent Bulb is hardly used nowadays with CFL and LED Bulbs dominating the market of household lighting. For the same unit of lumens (unit of light), a LED Bulb uses 6-8 watts and a CFL Bulb uses 13-15 watts whereas an Incandescent Bulb uses 60 watts of energy. Thus, CFL and LED Bulbs are preferred due to their Energy-Efficiency.

Apart from the efficient use of energy, the CFL and LED Bulbs also last longer and are thus cost effective in more ways than one.

Even though LED and CFL Bulbs come with warranty statements, it is advisable to buy them from a reputed company so that the inconvenience of using the warranty card does not even arise. One such company is LedLightDepot which provides the online sales of lighting in households and industries. Quality lighting products can be obtained from LedLightDepot at www.ledlightdepot.co.uk.

About Energy-Efficient Lighting

Lighting accounts for a considerable fraction of total electricity consumption in any country. Energy Efficient Lighting may be termed as minimum consumption of electricity for lighting without compromising with the quality of light. Energy-efficient Lighting might appear to be a small step towards conserving energy but when efforts are combined from every sector then there can be a major change. There are Energy-Efficient Lighting such as CFL’s, LED’s that not only save energy but are also eco-friendly. Let us discuss about them in detail.

CFL: This have been the first ever replacement to the incandescent bulbs. CFL stands for Compact Fluorescent Lamps. It uses a mix of phosphors that are used to emit soft white light. There is an appropriate balance of cost, energy-efficiency and light emission in CFL’S. These immensely reduce the electricity bills and are very cost-effective solution. Although mercury found in trace amounts in Compact Fluorescent Lamps makes their disposal difficult.

LED’s: Light Emitting Diodes (LEDs) bulbs are the best solutions for saving energy and cutting down your electricity bills. LEDs use luminance instead of filament as used in incandescent bulbs. These are capable converting electrical energy completely into light energy unlike incandescent bulbs that converts only 5% of electricity into visible light and rest is dissipated as heat. With less emission of heat, interiors too remain cool. Thus, there is a need to replace conventional light bulbs with LED energy efficient light bulbs.

Comparison Of Energy Saving Light Bulbs

Energy conservation has been an issue of concern of late. The pace at which we are exploiting our natural resources may have severe impact in long run. Keeping in this, you can contribute your towards the cause by using Energy Saving Bulbs. And you need to be aware of the energy efficiency of different bulbs to make wise decision. There are mainly three types of Light Bulbs, namely Incandescent Lamps, Fluorescent Bulbs and LED bulbs. We can compare different Energy Saving Light Bulbs on several parameters such as lifespan, heating effect and cost.

Types Of Light Bulbs

Incandescent Bulbs:
Incandescent Bulbs had a strong foothold in the market till there was an ignorance regarding energy conservation. These are bulbs with a filament which when heated to high temperatures using electric current emits yellow light.

· Lifespan: Working life of incandescent bulbs is not much. They can sustain for few months only.
· Heat Effect: Incandescent light bulbs heat up the surroundings. This is due to the fact that maximum amount of electricity is converted into heat and a small fraction is converted to light energy.
· Cost: Although Incandescent Bulbs are not costly, high electricity consumption categorizes them under costlier investment than others.


Compact Fluorescent Lamps (CFLs):
CFLs were the first replacement to incandescent bulbs. These are Compact Fluorescent Lamps that use mercury to emit light. Due to presence of mercury, disposal of CFL’s has become questionable in many countries.

Lifespan: Lasts at least15 times longer than incandescent bulbs.
Money: These are costlier than incandescent bulbs but consume very less energy as compared to them.
Heating effect: Produces much less heat as compared to incandescent bulbs.

Light Emitting Diodes (LEDs):
Light Emitting Diodes can either be conventional semiconductor diodes, organic or polymer diodes. Due to their higher efficiency there demand is on rise. LEDs produce light by luminance and not through heat filament. Moreover, Light Emitting Diodes do not contain any mercury content, thus are safe to use and do not harm the environment in any way.

Lifespan: These last 25 times longer than the incandescent bulbs.
Money: Though initial cost might appear high but these cut down the expenses by consuming very less electricity.
Heating Effect: No heat is produced through LED bulbs, and thus helps in keeping house or office area cool. This lowers down electricity consumption required by cooling appliances.

Thus, going for LED option at homes, offices, etc. can be the most cost-effective solution to cut down your electricity bills.
