Topled Ufo with the 3watters would be better than the 2 watters ebay crap ufos. Or the Vipar 180w Ufo is also good.I use a 180 w Topled in the small Tent and it works out only when it gets colder i might need the extra cfl in there for the heating.
I'm using a Topled UFO 180 watt in my veg cabinet. It's lighting a 2'x2'x5' ( 60x60x152 cm ) and it lights it perfectly. My young plants are loving it a growing nicely I used short pieces of light chain and s-hooks to mount it within a few inches of the top of the cabinet. I have a 2" intake hole and a 4" computer case fan for exhaust. With the cabinet closed tight ;last night, temps in there this morning were 84F ( 28.8 ) I'm going to cut another intake hole, but the temps were still withing reason.
Get a 180 watt UFO, it would be a perfect size for your area.
