Best thing to do is buy larger than you need and put it on a dimmer or tstat to dial it in.

You should be able to put it on one side of the tubs to give them a boost. I actually put a bulb over one side to create a hotspot and good ambient temps. That was just for one tub though.

I think I would try stacking the tubs and putting the light on one side. You may need two lights for all the tubs you have that need heat.

Shutting the vent will certainly help. If it's metal you can buy a sheet magnet that can go over all or part of it.... If it doesn't close well with the adjuster. I just closed mine completely in my snake room.
