I think I just blew out my first light bulb. It seems I've read about replacing them somewhere in the forum, but I don't find anything when I try searching with key words. The manual instruction seems fairly worthless.First, it doesn't mention that it's a no-see-um affair. I removed the cover and the plug that I feel, feels nothing like the picture I'm looking at. It also shows a retaining cage which I can't feel either. I don't want to break anything by forcing it. What am I missing?
