I think I am good for now on the inside of my horse barn, but I was looking at one of the fixtures on the outside of my horse barn and it is an indoor fixture! Needless to say, I need to replace it, but I am not quite sure what to replace it with yet. I saw a 500 watt quartz halogen at my local Menards earlier today, but I have also considered a mount that holds a pair of flood lamps side by side. Does anybody have any thoughts on what I should consider to help me make my selection?
