Agreed. If we see new heatsinks (at an affordable price for the average DIYer) that can run these boards at 200w, they will certainly seem more sensibly priced. But even then, that would be for those who want to run them high above the canopy, and honestly, I think it's sort of a step backwards. The 120 and 132 make more sense to me. Spread those diodes out so you can lower your fixture and achieve greater uniformity. That's why strips are currently killing it here on RiU.
What I want to see from HLG are variations on the 120/132 - a 90 CRI, Nichia-based 132 would be very popular, I think. And also, some longer boards - a double-length board with the layout of the 132 (264 diodes), at or near double the price, would be fucking KILLER. Run it at 150w, no heatsink, and get a hell of a lot more canopy coverage. But hey, I'm no horticultural lighting pro, and I know that HLG knows more about this than I do, so I'm just spouting, I suppose!
