Commercially available red light panels often combine red and near-infrared light, may be too bright for direct eye exposure, and may include eye protectors.

“a lot of the commercially available red light panels that you'll find out there combine both red light and near-infrared light. However, I want to emphasize that most of the panels that are commercially available are going to be too bright to safely look at very close up. And in fact, that's why most of those red light panels are designed for illumination of the skin and oftentimes arrive in their packaging with eye protectors that are actually designed to shield out all the red light.”
