The coverage of COB is 2'x2', so the coverage of 4 COB is 4'x4', Since the wattage of COB is small, One COB is only 120w, so if you want to add one more light, I recommend you SP250, the wattage of SP250 is 245w, it's smaller than TSW2000(310w), Besides, the SP250 is a rectangular design, so it can fill the light better if you put it in the middle. I hope my Suggestions are usefulI have a question for Sara I have a 5x5 Mars tent and I have 4 Mars COBs will the 4 COBs be enough light for that size tent or do I need another light in the middle and if so which would be better an SP250 or the TSW 2000 or another light ? I also have some head room restriction due to the carbon filter and fan
