Yikes!
This set off my bullshit detector:

"Accuracy. Plants experience their peak growth when given the proper wavelengths of light that correspond to photosynthetic pigments. If those wavelengths are off by more than 1%, a grower could end up with a 200g yield instead of a 400g yield."

Puhleeze!

Could be written by some dolt in marketing, so I'll go back and dig a little.
