No. I am thinking of the wavelength measurement of nanometers. I will take your example of a 635nm LED. Now this LED is sold as 635nm. Is 635nm it's median wavelegth? Does it for instance product light in the 630nm and 640nm range? I am not in any way refering to the lumen output which is a useless measurement as far as plants are concerned.
