Shenzhen Kehei Lighting Technology Co.,Ltd is a dedicated provider of LED lighting. Our constant independent R&D has won us several design and utilization patents in this field. For example, we have initiated in using magnesium and Aluminum alloy as the heat sink material for our spotlights, which dissipate the heat 70 percent faster than aluminum. We also continue to develop new generation heat sink materials such as aluminum nitride to meet the heat dissipation demand of high power LED lighting.
