SANSI 3000-6000LM LED Bulb 3000K 5000K A19 A21 E26 High Lumen Home Workshop Lamp
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.
