Lighting suggestions for 1m x 1m tent. I have a Mars Hydro TSW2000, what can I fit in tent for Flowering?

Title says it all. (1m x 1m is ~ 3' x 3') I've been reading and a lot of people have stated that for flowering, the Mars Hydro TSW2000 is not going to make the cut.
First grow in a long time, and only doing 2 plants. Any lighting suggestions that would assist an increase in my yield and fit into the area of my tent beside my TSW2000 would be appreciated.

Good enough. For two plants in a m2 lightning won't be a problem.
