This was once a flatbed-scanner.
I extracted the fluorescent lamp and the circuit board needed to drive the lamp. Then I feed the wires through the goose neck down the the battery compartment which is an old flashlight box. 12 AA batteries fit in there, but as this is slightly insane, so I added a standard 12v connector (also from the scanner).
In order to protect the fluorescent lamp I used a pvc-tube and a small plastic box which once contained screws. I also painted them black to fit in with the battery compartment.
