The space is 16" x 30", 48" in height. 50 CFM passive exhaust. With a 70W hps security light, the temp is 80-82. This light has the built-in ballast which I assume contributes a lot to the heat. It would be nice to upgrade to a 250 hps, so the question is... Which would be hotter, the 70W...

8 42watt @ 2700 lumens will only give you 2700 lumens. But having eight of them will give you better coverage. Put them as close as possible to the plants.
