Thank you for such a thorough post!
I suppose I should have been a lot more descriptive in the original post.
The basement was unfinished when we moved in. My dad pretty much threw up all the electrical on his own. He does construction for a living, but by no means is an electrician so I'm sure that could be a major cause of my problem! I currently have the dome (day/night) right into the wall socket, while the UTH and fluorescent light are shared on an extension chord. I've been meaning to buy a surge protector supply so I will stop by Walmart after feeding to see if that will help. I considered that my dads shoddy electrical job could have been an issue so hopefully changing the way things are plugged in will help a bit.
Your overall temperatures are also very similar to mine! It's just that I have to buy a new bulb every week (and now a new ceramic dome because the switch melted or something) that's the problem. I'd rather be cost and energy efficient, obviously! ;]
