Hello I am after some opinions on which one to purchase? Anyone personally used either of these products? I am leaning towards the FC6500 although it is a little more expensive because I have read this from a spider farmer rep.. “Due to the insufficient supply of Samsung chip and Meanwell driver, we have to find alternative suppliers. After a long period of comparison and testing, we selected Seoul chip and another LED driver, which are basically the same performance and price. They are just not that well known, but the quality is great too.” Thanks I’m advance for the help guys!
