I wish I could tell you whether or not 250W would cover that space adequately, but I honestly dont know from the top of my head. I'm sure someone could tell you though.

As for heat; my 250W doesn't produce much heat at all. The plants have been less than 10 inches away from it at points and showed no signs of high-heat-stress. So, I firmly believe using a 250W light in a 2ft x 4ft space (w/ventilation) wouldn't be a problem.
