1. It has a service life of 50,000 hours to 100,000 hours, which is ten times longer than that of common energy-saving lamp, even 50 times as long as that of incandescent bulb. 2. It saves 50%-90% power consumption than traditional lamp. For example, if a metal halide of 100W is replaced with a LED lamp of 18W, it will have the same or even higher luminance, which saves over 50%-90% of electric charge for you. 3. High luminous efficiency: All spectrums of LED lamp almost focus on the visible light frequency and light efficiency can reach 80%-90%. Lighting effect of it is 1.6 times of that of common energy-saving lamp,4 times of that of halogen lamp and 5 times of that of incandescent bulb. 4. With no ultraviolet rays or thermal radiation, its light has no heat or radiation. So it keeps value of your products and avoids xerosis cutis and ambustion of your employees caused by long time irradiation of lamp. Meanwhile it creates better shopping environment for customers. 5. Its lamplight has strong penetrating power and good third dimension. Thus it can undertake long-distance pointolite projection on jewelry and enhance the level of jewelry, showing the value of jewelry infinitely. 6. Safe: Working current and voltage of it is within safe range of human body. 7. Green and environmentally-friendly: Without pollution, its waste can be recycled. Unlike traditional lamp, it doesn't contain mercury or other harmful substances. 8. Its lamplight has good color rendering: Color temperature value of the lamp ranges from 2,600K-10,000K (Warm white, natural white, pure white and cold white are optional.)
