Isolated wavelengths used in red light therapy (650-680 nm) and infrared light therapy (800-850 nm) are unnatural, although photobiomodulation from these wavelengths can be beneficial.

“for me I used to have all these red LEDs and do like red light therapy in my home as well but those are really isolated wavelengths you're getting like 680 or 650 and then maybe for infrared light therapy you're getting you know 800 850 and you know it's great because photob biomodulation is real and those wavelengths can be helpful but it's also unnatural”
