Rubbermaids and low wattage HPS

What is the highest watt HPS you could get away with in a 36gallon Rubbermaid clamshell? I'm just looking for more lumens/ft^2 than CFLs can deliver. But I also need lots of ventilation which can be accomplished.

Ne thoughts/comments?

eh id bet 70 watts would be a safe bet, any higher would be pusin it. What i did with my micro box is but 3 cpu fans directly aiming at the 150w hps, and 3 for the outake. The area is close to the size of a computer box.

Id say put two for the intake shooting air right on the hps and at least two venting air out.

Good luck with that, would like to see it.
