This is my Arduino based desk lamp.

2 Potentiometers allow for changing hue and brightness of the Neopixel ring in the flexible arm. The button allows for turning the lamp on and off, and for switching from color mode to pure white. In white only mode, only the brightness can be adjusted. The Arduino code can be altered with different patterns of course, so the lamp can be used as an indirect mood light as well.
The segments slide into eachother with quite a bit of friction. Putting a drop of silicon oil might help.
There is a canal through the center of the segments where three wires for the Neopixel should pass. I used stiff 4 conductor telephone wire as it made it easier to push the wires through.
I used a 12V power supply because I had it laying around. A 5V power supply will also work and is even simpeler. The stepdown converter is not needed in that case.
Powering the Neopixel ring directly from the Arduino might work, but in white mod
