Spanking at bedtime?

So my two year old never ever will just go to sleep no matter how hard we try or how tired he is. Some nights he'll fall asleep on the couch and well put him in his bed and he is wide awake. I have a stric bedtime of 9pm. We took away naps to make it easier for him to go to bed at night. (But I know my husband is giving him naps during the day when I am working) but my husband is now resorting to spanking him Everytime he gets outta bed and turns the light on and his little fan off. Please don't reply if you don't believe in spanking. But for those that do, is it ok to spank him for this? He knows it's bedtime and most of the time he is tired, he just doesn't want to stay in bed.
