LED Light Bulb

With the development of the world, humans are looking for more and more environmental friendly means in our daily life. Some factories are adopting clean energies instead of petroleum. Families are also seeking ways to protect the environment. Some purchase water-saving washing machines and dishwashers to save water. Some use solar water heater instead of gas water heater. All these devices contribute a great deal to our environment.
However, some people may have never heard of LED light bulb or have never used one. Then it is the right time to keep up with trends.   
Having been improved technologically for decades, the luminous efficiency of LED has been improved greatly. The LED light has a double to nearly seventeen times luminous efficiency over that of halogen light, and up to triple luminous efficiency over fluorescent light. The monochromatic light is good with narrow spectrum and can be visible without the color filters.
The LED light can consume less power. The driven voltage can be as low as 1.5V, and the current can be 15-18milliamperes. Since the light has a high reaction speed, it can be operated at high frequency. Estimated by Japanese experts, its power consumption can be one-eight of incandescent bulbs. So the LED light can obviously save energy.
The LED light has a longer life span over other lights. Unlike electronic radiation emitting lights, LED light will not burn the filament, therefore avoiding optical attenuation. In addition, because of its small size, tiny weight, epoxy package and its excellence in withstanding high-intensity mechanical shock and vibration, it can be hardly broken. The average life span can be 25,000 hrs. 
With low heat, non-thermal radiation and cold light, the LED light can be safely touched. It is light in color, soft in weight, and non-glare. There is also no mercury, sodium and other hazardous elements in the light. Even with a built-in micro-processing system, users can control the luminous intensity and adjust the light-emitting modes to achieve the best light.
 The last but not least, the LED light is friendly to the environment. With good solidity, anti-shock performance and impact resistance, it is recyclable and will not pollute the environment.
Being so energy-efficient and environmentally friendly, the LED light bulb will be the best choice for users.
