I see. There's certainly nothing wrong with getting "H" designated lm301 chips. When I was first getting into these quantum boards it was a bit confusing for me. GreenGene and several other industry trusted individuals (Stephen from HLG) confirm the lm301b and lm301h are the exact same chip. Just a bit of marketing confusion (intentional or not) on the part of Samsung. I'm not sure what boards are hot in this thread presently, but here are the two 110W boards I just ordered from
Shenzhen Yixiou Technology Co on alibaba for $187.60 with tax:

This is my 2nd order with Yixou. My first order was a
660W board with the same chips. The 660W board is basically 6x of the two boards I linked to above. It works great, but I feel breaking the boards into smaller panels produces a much better spread of light over the canopy. Cramming too many chips and boards together in a small frame creates a lot of intensity that I feel is best spread across the canopy creating a much larger and more evenly distributed light foot print. I believe HLG addressed this very issue with their new Scorpion boards which separates the panels rather than cramming them all together in a tight package. The vendors on 'baba will have their own Scorpion's soon enough for half the price of HLG.
