Supplying power.
One of the trickiest parts was finding a small 5V WW/CW LED controller. Most were 12-24V and I did not want to ruin a 200 dollar lamp. Any LED controller should work, but make sure that you are using 5V, and that the controller supports WW/CW.
For power, just a standard USB 5.5 x 2.1mm DC Male Connector, or splice in the power from the original cord, not preferred.
