I see you chose to go with Meijiu for the boards. I have bought and sold their boards before, and have feedback from a customer that that board was brighter than a Closet Case 140 from spectrum king when hung side by side. The CC 140 was $200 more expensive than what I sold him my kit at (around $120).
Despite that positive feedback, I was disappointed in that it was only 1.6mm thick. Their 240pc 36V board is the full 2mm and bigger size wise, and may be better at heat dissipation. when the customer switched the driver out to a Meanwell HLG, he reported a reduction in heat over the driver I sold him (meanwell LRS 100-48). Just sharing my experiences but yeah, it is a decent board imo.
yeah they were pretty much the only ones that weren't trying to imitate the look of HLG. I found a Light laboratory close to my house that will do a complete sphere test for $350. I'll probably get one done next week. I'll keep you posted
