What's the difference between SANSI LED bulbs which adopting SANSI Patented Ceramic Technology with other bulbs?. PATENTED CERAMIC TECHNOLOGY: 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, effectively reducing 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.
