LED advantages:

1. High efficiency and saving energy:base on the same lums,led light 1000 hours can cost 1 degree of electricity,,and saving lamp 100 hours 1degree of electricity, normal incandescent 17hours can cost 1 degree of electricity.

2.A long life span:LED living time is more than 50000 hours,normail saving lamp is 6000hours,incandecent lamp is 1000hours.

3.Healthy:LED ray is not contain purple ray and red ray,nonradiative,and the others have the two kinds radiative ray.

4.Green and environmental:it is free of mercury and lead,used to recycle and utilize,not bring EMI,and however normal lamp contains mercury and lead,electronic ballast will arise EMI.

5.High efficiency:less heat,90% electric energy can transformed into visible light.Normally incandecent lamp 80% electric energy transformed into heat,only 20% electric energy can changed into visible light.

6.High safty factor:the voltage and currents is more smaller,no safty risks,it can used to mine and dangerous place
