All LED manufactures have multiple bins, they're just not talked about much at places like ebay. When you buy the cheap ones, you get whatever bin they happen to be selling, and good luck finding out exactly what that is. You need to be careful you are getting the correct bin # for what you want. There may be 8 bin numbers for a 465 nm, and some may actually be something like 440 or 490. You especially need to be careful because the slightest adjustment in wavelength can make a huge difference in chlorophyll activity. (see chart)

This would defeat the purpose of the scrog, which is of course to spread out the canopy evenly to take full advantage of all bits of light and space.

If people have done much reading they've seen these charts I've fine tuned, but here they are again for your convenience:
