In the past few years, we have covered a bunch of awesome steampunk creations here, including lamps, robots, and sculptures. Want to build your own steampunk lamp? paolo marinelo has shared a guide to show you how to get started. Loulou is an articulated steampunk task light you can build with the help of a 3D printer and laser cutter.
As you can see in this GIF, adjusting the light is pretty convenient. You can find the instructions here.
