Yeah its about half what you need, if not a bit less than.
You would want at the very least a tsw2000 (its more rectangle than the ts 2000) or ts3000 for more light.
Its hard to pick, one is a bit under and one is a bit over what you need.
You might want to look at the spider farmer lights too. 300w is good for a 3x3 but the mars is a bit less efficient so I would want 350w but they don't do a 350, its 310w for the tsw2000 or 450w for the ts3000
