I'd say the first question before recommending anything is how much space are you flowering, and how budget conscious are you.
Those lights are very good, but also not cheap.
The most efficient boards are often not the correct choice for everyone.
Diy lights you can get within 10% the efficiency of those for under half the cost. It does take abit of work on your own assembling though.
For non diy id buy a meiju or kingbrite before a HLG. Same parts way less $ because its a chinese knockoff.
I cant justify spending $1000 on 600watts of LED tho.
