Yeah LED's are similar to each other but there are differences in how they radiate energy (pattern) and how efficient they are etc.

CRI (color accuracy): 80 (pretty good but state of the art COBs are getting to 95 now for fairly reasonable prices)
Color temperature 4000k
Construction They say "corn cob" which I think means like something like this (on the inside):
This style of construction with LEDs on the sides makes for a wide distribution of light instead of focused which means it will be less efficient at covering your space but WILL work. I suppose they are designed this way because for general lighting you want broad coverage as opposed to more focused light.
LEDs without any optics radiate in a rather inefficient manner (Lambertion) and so construction type matters. Color temperature obviously matters to the plants but may not be super critical to actually producing a crop (just better if the temperature is close) and the color rendition accuracy as well. An LED can have a specific color temperature but still have a distribution of colors that is hit and miss for plants.
If one wants to use the Lambertion pattern of a typical chip LED then the
Quantum boards are good because you have so many LEDs scattered and are close to one another giving a very consistent coverage with consistent intensity. However, a COB style (chip on board) array with a small lens (the kind that are built into the holders) will tame the pattern of the COB type and if someone wants a more focused pattern there are reflectors that can be added to the holder.
I think it would be a way for someone to make a budget entry into growing with say 3 of these in a 2X4 Veg tent.
Lambertion radiation pattern (intensity is shown by the length of the lines). Most of it is downward but a lot of energy is out the sides:
