True 670nm Deep Red Light & Zero Blue Light:SANSI uses true 670nm deep red technology to completely eliminate blue and green light, emitting a comfortable and soft red light.

SANSI COC Technology: SANSI‘s patented technology replaces the traditional MCPCB aluminum substrate with a non-conductive ceramic heat sink and directly solders the LED chip onto the ceramic heat sink.
