get one of these. it beats HPS/MH with a fraction of the heat. Phator has one, ask him
the only issue with folux boards is you are probably not getting top bin samsung chips: if you have no problems with the issues you may face buying cheap chinese knockoffs then go ahead. i own a few cheap chinese LEDs myself. horticulture lighting group has a business relationship with samsung as their horticultural partner. if you buy from HLG you can be sure that the board you are getting top bin (cream of the manufacturing "crop") samsung chips which further ensures you are getting the correct specs when you actually purchase the light. its likely that the reason why folux boards are cheaper is because they buy the lower bin samsung chips to complete their boards... this could mean the difference from a board that maintains spec for 2-3 years vs 7-10.
