its 4' tall x 2 1/2' wide x 1 1/2' deep.(exactly why im doing a scrog, lol) im pretty sure it ends up being 6 square ft. well i am going with the jh, but its going to be next grow, i have 3 unknown mothers right now. cloned off friends, parents, outdoor plants. we shall see how it goes.
10" is not a whole lot of vertical space, merc...
Anything over 250W will burn the hell out of your plants with your clearance, and a 250's still gonna be hot/too intense even with a cool tube. I used to run a 150W in a 2' x 3' x 3.3' (see attached), had good airflow, and still used a tempered glass partition (or shield) between the light and the plants to allow the light within ~2-3" of the top canopy. You'll lose about 8% of the intensity from light going through the glass, but you can get 'em much closer, so you more than make up for it in 1/r^2 gains. And they won't burn...

My 150W system would pull a good ~5-6oz that way with NLxBB clones in a nice tight ScrOG (actual garden area was ~2.7 sq ft). With your small area, that'd work fine, too. 50w/sq ft is more a good rule of thumb with larger garden sizes (I've run those too), I've found.
Cheers,
