Red light, near-infrared or several colours?
Choose by the documented light channels and intended use. More colours do not automatically make a better mask. Ask which wavelengths operate together and whether the listed modes are supported by the actual model supplied.
Mask or panel?
A mask follows the face and is selected for fit and contact materials. A panel is positioned at a working distance and needs a suitable support. Neither format makes the other interchangeable: compare the area you want to cover and the way you will use it.
