LEDs are light emitting diodes used in most lighting appliances where a lot of energy savings is enviable. They are moisture resistance and shockproof because of their resin coating. This latest technology does not overheat as well as uses only a small wattage of electricity as compared with other filaments that depends on repeated relay of electrical currents to continue lighting. The latest replacement for these halogen equipments is the GU10 LED bulb. One can substitute this unit for compact fluorescent lamps or minimal energy efficient halogens simply by plugging it to the fixtures.

These new style of lamps are made from mercury- free materials and from impact immune plastic hence will not fall short after few months or crack by accident. GU10 LED bulb is quickly gaining popularity as an alternative to CFL and halogen lamps because it provides a long life of five to ten years of regular use.

These bulbs produce directional light that is concentrated on one area, which is a great choice for a number of lighting applications such as accent lighting, spotlights, recessed lighting, light track, table lamps and decorative lighting. Therefore a person can employ LEDs in locations where bright light is required for instance, inside cupboards and under cabinet units.

Suppliers of GU10 LED offer various colors for these bulbs, consisting of a yellow- toned, and restful white, a chilly white of gentle tones, a soft white and day light unit which releases a bluish white shaded beacon. The yellow tinge of soothing white selection adds to an intimate mood of a dining event for two. The gentle white touch is ideal for the living room whilst the daylight unit might be well suited for an office or workshop.

Brilliant light bulbs function through heating of a metal filament in order to produce light and for those who have ever attempted unscrewing a lit bulb knows the quantity of heat they produce. In fact, the much energy they produce is transformed into heat and not light which is very poor. On the other hand, the GU10 LED generates little or no heat, which makes it very efficient.

However, the only disadvantage to this recent type of lighting device is that they are focused only on one area hence not a very good quality choice for wide area luminosity. They function well as spots or in a display.

With a GU10 LED bulb, a person does not have to worry about the burned out lamps for a long time. The more replacement model one makes the higher electricity consumption saved. As more people switch to this newest technological advancement, the world will bring about a well-illuminated future for earth-friendly environment.

That the world is changing is undoubtedly an irrefutable truth. That we have to change with it is without a doubt. In some areas, the earth has been regressing and it is true in the area of environmental condition. Time has come to make a change especially in conserving electrical energy. Now, the introduction of the PAR20 LED bulb.

Its several applications starts from lighting airplane cabins to reading light bulbs and even floodlights. The LED trend has spotted since its advent in 1962. Its adaptability can no longer be brought into question. But it seriously is not the only thing it can give. The advantages are many since they are practical.

As energy saving lights, most of these bulbs have been able to take up very little power. They run on average, approximately nine watts which happens to be significantly less than conventional bulbs’ usage. Although some fluorescent types still out strip this effectiveness, there are more persuasive reasons to use LED bulbs

Over the long period these lights have proven to be quite economical especially in cutting down the ultimate overall costs. Generally, statistics showed that they are 90% more efficient compared to conventional bulbs.

Coupled by this rise in efficiency will be the increased longevity of these bulbs. It is estimated to function to as much as one hundred thousand hours run time. The normal lifespan is actually approximately fifty thousand hours, though the dimming factor is also one aspect when stretching this lifespan. Unlike ordinary bulbs, which will just stop altogether, LED bulbs will slowly darken over their lifespan before eventually giving up. However, there have been advances recently in non dimming light bulbs.

There is also this issue of flipping the switch to maximum wattage in a couple of micro seconds. There is no question of waiting for the glare of light to stabilize. This is almost instantaneous even in cold temperatures thus, making them ideal for use on porches and also as security lights. Their outdoor capacity is unparalleled.

The increased efficiency is a consequence in reduction of temperature. Therefore there is less wasted energy discharged by the light emitting diode bulbs. This makes it effective in lighting purposes for temperature sensitive settings especially in controlled environments like medical labs and such.

They are designed to fit perfectly into existing sockets. This makes them an ideal crossover component as there is no further costs to accommodate these bulbs. It is as easy as changing the conventional bulbs.

They do not discharge ultraviolet light but there have been worries about the levels of blue light that they give off. However, all in all the issue of mercury is a plus since direct exposure to this heavy metal is also a cause of trouble to most people.

They may or may not allow dimming depending upon the manufacturer. LED bulbs are also available in a variety of colors and angles as well as wattage.

As far as requirements are concerned the quantity of the order might allow for flexibility in specifications such as screw base length, angles, wattage etc. The PAR20 LED bulbs are indeed a breakthrough in lighting technology.

China will stop imports and sales of incandescent lamps beginning with 100W lamps from October 2012.

China has unveiled its three-step plan for phasing out energy-inefficient incandescent lamps. The announcement caused shares in US-based LED maker Cree (Nasdaq: CREE) to surge by almost 10% on November 4.

According to the Xinhua News Agency, the phase-out will affect imports and sales of incandescent lamps, and will proceed as follows:

100W and above – banned from October 1, 2012
60W and above – banned from October 1, 2014
15W and above – banned from October 1, 2016

The announcement was made by Xie Ji, deputy director of the environmental protection department with the National Development and Reform Commission (NDRC). The plan shows China’s determination to press ahead in its efforts to save energy, reduce emissions and curb climate change, he said.

China is a major manufacturer and consumer of lighting products and is the world’s largest producer of both energy-saving and incandescent bulbs. In 2010, production of incandescent light bulbs totaled 3.85 billion units, and domestic sales stood at 1.07 billion units, said Xie.

Power consumption for lighting in China accounted for 12 percent of the country’s total electricity use in 2010. The NRDC expects that the plan will enable China to save 48 billion kW.hr of power per year and reduce emissions of carbon dioxide by 48 million tonnes annually.

Christophe Bahuet, deputy country director of United Nations Development Programme (UNDP), was quoted in the Xinhua News Agency article as saying: “Phasing-out incandescent lamps in China will not only promote lighting technology progress and lighting industry upgrading and optimization, it will also make a positive contribution for realizing China’s energy conservation and emission reduction goal.”

China’s phase-out ties in with legislation in other countries and regions to stop using these products. Europe’s incandescent phase-out affected 60W-and-higher lamps from September 2011, while the USA begins to a nationwide ban on 100W-and-above incandescents from January 1, 2012.

In addition to Cree, the Nov 4 announcement also had a positive effect on the share prices of MOCVD equipment maker Veeco (Nasdaq: VECO, up 10%), sapphire-wafer maker Rubicon (Nasdaq: RBCN) up 18%), and LED maker SemiLEDs (Nasdaq: LEDS, up 31%).
