3x3 is 9 square feet. You need a min of 3000 lm/sqft, ideally somewhere over 6000 lm/sqft.
Each of the shop lights I originally posted were 8255 lumens. You would need a min of 3 or 4 of them to light up your area. Ideally, I would put 6-7 in the room... but that's ideally. If you can only find the black cased ones that put out only 6500 lumens, you may need an additional 1 or 2.
If you're on a budget, I'd say go with 4 of these for your space. It will cost you $100 up front, but will keep your room lit and be as economical on your electric bill as an HPS of similar luminosity. Keep in mind that these (unless they come out with other bulbs) are only for vegging.
As far as your space goes... You'd be safe planting as close as 2 per sqft. I personally have 10 plants in 8sqft, or 1.25 plants per square foot. The more plants you have the less time you have to veg them for to get them to fill your area.
