New Sun Suggestions(Pros Pls)

[Beggie]

Hello. I would like to make a new light. My space is 4x4(1.2mx1.2m). I can manage pcb boards and diodes and cobs. So I dream of having a unique design. I like chilledgrowlights designs. I believe if I make it myself it would be a lot cheaper right? What is your thoughts and suggestions? Thanks in advance.
