The Hans panel is supposedly regarded as one of the very best of the previous generation grow LEDs, and it is made with top quality components. But it is still previous gen tech.
HLG and other brands using quality phosphorus-coated white LEDs (COB or SMD) will be more effective, offer a better spectrum, and cost less.
DIY'ers build lights with the best components for under 1usd/watt. Times they are a-changing!
Edit: SolSkins are nice too! LM561C-based boards/strips seems to be taking over for COBs, lots of HLG clones and similar on Alibaba.com
