I had to use 3 lights with a combined wattage of 750 max to power this tent in flower. Compared to a 4x4, this tent is much more difficult to 'light up'. Also, I set it up by myself in a 10 x 10 basement room with half an inch clearance from the ceiling.. I'm pretty proud of that.
Overall, It's well made for the price and I'm really happy with it so far.
