DIY LED vs manufactured panel

[safehaven]

So, I have been doing A LOT of reading on LED grow lights. I recently stumbled upon some information regarding DIY LED panels.

Using COB LED technology, building my own LED panels is completely within my abilities and at 25% of the cost of a high end manufactured panel.

However, not much, if any, information is given on the performance of a DIY panel. I realize that there are many variables that could affect performance of a DIY panel.

Generally speaking, is a DIY panel using 100W COB LEDs, that produces comparable wattage, grow as effectively as a high end manufactured panel?

For example, in one article I was reading the builder built a panel of quantity 16, 100W Cree COBs, alternating 2700K and 3500K. The COBs were running at, I think between 60% and 65% of rated output, for a total of about 1000W. Will this perform just as well as a high end, manufactured 1000W LED panel?

Since I loves me some DIY, I'm going to sit in the corner and see what other members say.
Typically I DIY to learn and have fun, but rarely save much (if any) $$$.

I made a diy led with 4 100w 3000k cree cobs and a meanwell driver. It yielded very well in my comparison . I think i built it around page 6 in my journal.
