a light mover is not optimal. you have take into account the amount of time certain areas of your tent will be receiving less light than others. if you have 2 lights going all the time then there is never such a time period. therefore 2x lights > light mover - every time.
i've got 2x 400 watters and was thinking about putting them in a 2'x4' tent. then i remembered you only need 50w/sq. ft. so let's do some math:
2x4=8
800/8=100 - so with 2x 400w you would have 100watts per square foot. already twice what is believed to be optimal.
500/8=62.5 - 2x 250w is 12.5 over 50 but i would be comfortable with that.
if i could find a nice 6'x2' tent i think that would be ideal for my 2x 400 watters. that would leave me with a little over 66 watts/sq. ft. if you haven't bought your lights yet but are dead set on having a 2'x4' tent, i would go with 2x 250 watters and rid yourself of all the heat control headaches to come. plus you'll have a more efficient grow due to a cheaper power bill from smaller lights and lower ventilation requirements.
hope i helped
