I have a Croton bell how do u take care of them?

I have a croton bell plant the colourfull one. When i got it home I transplanted it and waterd it good. The next day it wilted big time. I don;t have a window in my apt that has 4 hrs of direct sunlight. I was wondering if I could use a lamp for the 4 hrs for the sunlight it needs and then put it back on my window ledge. I really could use some help becuase I don;t want my plant to die. Thnxs so much
