The "lightbulb" is a 5-sided spiral that forms the general shape of a lightbulb. I made this a few years ago as a test piece and I've updated it just for you.
I've included two sizes:
Full size: about 4.8 inches tall
Half size: about 2.4 inches tall (...yep, that's half...check!)
I've also included each STL file in two resolutions.
This was used as a benchmark print in Make Magazine's 2013 3D Printer guide!
