Well you have a 1.5 cubic meter space there. (if your height is 2m and not .2m) In a perfect system, it will exchange the air 150 times per hour. If you are using this for ventilation, it will be more than adequate. If you are using it for cooling, we would need to know what kind of lights you are using.
