my question would be why are they so much. You can get a 660nm on amazon for 20 bucks.https://www.amazon.com/ABI-Booster-Flowering-Spectrum-Enhancement/dp/B01H2Y5U4M@LifeGivingStore I dont meant to be rude but I gotta ask....whats the catch?
How are you able to sell it for so much cheaper?
How much more can the different wavelength leds be?
IMO 660nm is close enough as none of these are monochromatic but have a spread of wavelengths around the nominal one.
