I made this lamp for my nephew this Christmas. I used 4 UV LEDs and a few straws to give the effect of 2 tiny black light tubes. I plastic welded the store bought UV Pin Art piece to a project box from the 'shack as the base. The wires run through the spacers and down into the base. There is an ON/OFF switch on the back. The whole thing runs off a 3.2vDC AC wall adapter. It is really cool and was a big hit.
