250 grams would be around 9.5 oz or about .6 pounds. If you use the watts/pound rule and multiply 50 watts, 75watts and 100 watts X .6 you will get a good feel for what is needed.

So, if your all up weight is .6 pounds, 60 watts would be plenty. Of course that depends on what performance you want, which you did not state.


I won't get more specific than that. The goal here is for you to apply what you have learned, not to ask me to do it for you.
