i have bout the same setup as you, except i have a 600 watt light. the thing you have to think of which i didnt at the time is the next room probably uses the same circuit in your breaker box. you have about what i have in both rooms combined so if the next room is consuming alot of power you might overload the circuit. i know i cant run a vacuum on that circuit when the lights are on! learned that one the hard way. you should be fine with what you have though. I am going to wire a plug in my room that is on its own breaker to avoid this situation in the future, you might think of doing the same.
