Currently using an AC Infinity Ionboard 4x2. It's 200w. I initially thought of adding another. I like how the newer units have tracks. The light really hits the edges. I'm looking to either add another or add a FCE4800 from Mars. Trying to see if anything goes on sale.Optimally you want about 20w per square foot for autos (20/4 hrs) and 30w/square foot for photos (12/12) you have 12 sq feet so 240w-360w light so the light T RAEB recommended is just fine. That's with DLI 40 as target. The light you have seems to be Vivosun you could always add another. I always get carried away when buying imaginary lights but it's so pretty...
