Very nice lights for the cost
the 320 watt 3 plate DIY kit with a meanwell 320/1.750 were good lights at $450 now you get 1 pieced together for $220 to $270 depending on driver I’m using a lot better driver then come with the DIY kit a meanwell 480/2.100 it’s an amazing difference with the 2.100amp then the 1.750 makes a 3x better light a much more ever footprint and better penetration with the 2.100 I’m looking at using 480/2.800 amp driver I want 2 more set ups from HLG I’m just short the $$$ right now Christmas is coming HLG should have a good sale then 🤞🇺🇸
