Infrared LED's are the same thing as a UVB LED. Where Eye protection if possible. 




UV and IR are at opposite ends of the "visible" light spectrum. They are not the same.
UV-A 315nm-400nm wavelength
UV-B 280nm-315nm
UV-C 100nm-280nm (germicidal)
the UV (ultraviolet) part of the spectrum ranges from as short as 10nm up to 400nm (UV-A)
IR is Infrared and has a much longer wavelength and is mostly invisible to our eyes, although bright IR sources can damage the eye.
We feel IR radiation. It is heat. The IR part of the spectrum satrts at 700nm and goes up to 1mm in wavelength.
IR-A 700nm-1400nm
IR-B 1400nm-3000nm
IR-C 3000nm-1mm


I am talking to a chinese mfr. there is a thread I started called "perfect LED panel"  you can check out the details there.
price looks like its gonna be pretty good, and no minimum order :smile:

I edited once I read the rest and saw that someone already mentioned the UV/IR stuff
