It's a brooder clamp lamp that I got from Walmart. I've seen them at Home Depot too.

I put some netting over the frame to keep the birds away from the bulb and put a cord protector over the cord to prevent them from chewing on it. I tied clothesline rope to the lamp to support the weight so it wouldn't be dangling by just the cord, and put the rope inside the cord protector too. It's similar to this one:

The traditional way to find studs in the wall or ceiling is by knocking on the wall and listening for differences in the sound. I'm pretty bad at hearing the difference, so once I think I've found a beam I use a stud finder to make sure I'm right - it's got a magnet in it that reacts to nails in the beam. There are expensive stud finders that would probably do a better job, but the one I've got is a cheap one similar to this:

With pine cones, you can rinse them in water to get rid of debris, let them dry, and then bake them to kill any germs.
