Toal malarkey. An incandescent bulb gives off FAR more "infrared" than an LED. The only LED's that produce infrared emissions are those specifically tailored to do so, and they emit ONLY a specific spectral band in the infrared. And all "non-infrared" LED's produce virtually ZERO infrared, emitting only a narrow band around their specific designed-in output wavelength.

You may think what you like but for whatever reasons they work. Try it sometime when you have an ache or pain or other health problem. You will be amazed and possibly much better for it.

"You may think what you like but for whatever reasons they work."

It's not a question of "what I think". It's a question of what the facts of science are, and they are as I stated them. "LED therapy" may indeed have some beneficial results (treatment of infants for jaundice, for instance) through use of specific isolated wavelengths at high intensity, but the mere emission of infrared is not the reason.
