300W Equivalent A19 LED Light Bulb, 5000 Lumens E26 LED Bulb with Ceramic Tec…
PATENTED CERAMIC TECHNOLOGY: ‘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 systematic thermal resistance between the LED PN junction and the surface of the heat sink, resulting in faster heat conduction and higher product reliability, making ‘s bulbs perform with higher light efficiency.
