That was kind of my thinking mate, I was thinking of two 800s or 1000s maybe but I worry about all these knock offs, especially when there are two or three lights listed as exactly the same but blatantly different lights, build, design and all that. Technology and electronics baffle me, I just want a decent set of lights to expand my grow lol. I'd like a 4x8 but that's a fair few leds to cover.
