UV light is the main issue here. Assuming that it has a white plastic top along with it, I wouldn't have any concerns about using them within reasonable lit situations. Based on your specific situation I wouldn't even think twice about it.
If you're still worried about it, you could just throw a blanket over it, that would keep the light off and probably insulate it from any potential temperature fluctuations to some degree.
