I have a few different LED lights and would say blackstar is great for the cost. I would call gotham hydro and ask what they think. I use 2 of the (I think 240's in a 3.5x3.5 space and will soon be trying scrog for better results
You will want a filter and fan. Heat will build up with several lights going and if you want to lower the odor you will need a filter.
Hope this helps a bit, good luck
