Do your panels emit light?

Our panels emit far infrared heat radiation which produces no light. 

This means that more energy is focused on producing heat than unnecessary side effects. There are infrared bulbs and heaters which fall under the mid-infrared category which produce a red glowing light when turned on.  However, it is not nearly as efficient and is prone to breaking down. No light also allows for a very discrete form of heating as the panels also produce no noise at all.
