I just wanted you to know that Ive been researching the hell out of lights and this (PG640) is still my top runner. I just went and checked the VIPARSPECTRA ( https://www.amazon.com/gp/product/B09MTSY9G2?smid=A1BSXM5KIS5MZE&th=1 ) they've dropped it to $399 plus free shipping. Would you still go with the PG640?

EDIT: Also, do you know if the ProGro640 will work with the control language the AC Infinity controller has?
