SANSI's patented technology replaces the traditional Mcpcb aluminum substrate with a non-conductive ceramic heat sink, directly soldering the LED chip on the ceramic heat sink. This effectively reduces the system thermal resistance between the LED PN junction and the surface of the heat sink, resulting in faster heat conduction and higher product reliability, making SANSI's bulbs perform with higher light efficiency. The lamp body is made of special ceramic material, and the flame retardant grade reaches grade V0, the reinforced insulation structure means no risk of electric shock, its safer, the whole shell material reaches the WF2 anti-corrosion grade, which is more reliable and durable.
