My oldest son, the engineer, set up my Red Light therapy light, so I was able to get some sessions in this week.
3 of the buttons on the side are known by most, UVA, UVB, Red Light, but the COB button stands for Chip on Board, which must be a technical term, but it helps manage the light output.
COB chip
The lamp's concentrated light emission is powered by a 288W COB chip. It provides specific wavelengths in a balanced ratio and incorporates low flicker and low EMF technology for a soothing experience.
