I guess technically they call these lamps in the theater, but I'm calling them lights. They also work great in a film context.
You'll just need to add your own glass (and lightbulb). The rendered images above just use a simple metallic shader. If you download the .blend everything is packed into it and ready to go out of the box, but I'm sure you can come up with something better on your own!
If you have any questions, let me know!
