By frequency I ment wavelength.
And since LEDs only generate one specific wavelength and not a spectrum,
this would have impact.
I hope that most modern equipment operates with the same wavelengths
(around 900nm). Some old devices used around 600nm.
These wavelengths are not compatible. Ref.:

I really like this PDF. I feel more confident now that FIR will be the
only thing we want.
