The cost of LED light panels seem to be pretty outrageous for what you get. Has anyone ever made their own light panel? I would think that one could make a 24" x 24" panel at a fraction of the cost of the ones currently out there.
I realized you would need high output LED, preferably with a 5500 degree color temp, but it seems a little patience, a soldering iron and a few parts can save you a bunch.
If you don't value your time, yes DIY might save some money. But, if you put any $$ value on your time, and if there's any R&D or learning curve involved, it's often better to buy off the shelf.
