To have more flexibility in future grow rooms I think I will go with 2x HLG-320H-48B and build 2 fixtures for the strips.
They will be dimmed down to ~ 250w tho.
It´s a good point that I can save some money running them without heat sink at 25w. Heatsinks can be expensive as f**k here in europe.
Thank for you advice, they are very appreciated. And if you find the time to do a proper spectrum reading of these strips please let me know

Build/grow thread upcoming when they are finished.
