IR remotes work in buildings and arenas with Halogen lighting. One aspect is the sensitivity angle. Think of what happens when you are too far to the left or right of your TV when you go to change channels... nothing happens until you get in front of it. Other thing to remember is the signal is modulated on a 38kHz(?) carrier. Lights won't put that frequency out. So, the receiver is looking forward and not up and is modulated so the lighting shouldn't be an issue.
