April maker challenge 19- Inductive lamps

I used to have one of those super fancy Phillips electric toothbrushes. One of the cool features of it was that it charged by sitting in a cradle that inductively coupled to the toothbrush handle, so the handle could be sealed water tight and yet still accept a charge.

I'm fascinated by this and by the potential associated therewith. I'd love to try using this for other applications. The easiest is a setup where a coil placed under a table passes power to a device sitting on the table, and the most obvious candidate would be a reading lamp or a centerpiece that has lights involved. The result is a cool centerpiece that lights up without the inconvenience of running a cord across the table.
