SANSI RGB LED Light Bulb 4000LM 40W(260W Equivalent) Dimmable with Timing Remote
[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.
