Magnifying clamp-on lamp upgrade

I had an old clamp on lamp as the one shown in the picture and decided to give it a new life as magnifying lamp.
The lamp has been designed for a 100mm magnifying glass, a small [c&k toggle switch](http://www.ckswitches.com/products/switches/product-details/Toggle/7000/), 12V ledstrip and a 12V adapter as power supply.

Connector : needs support. 0,2mm layers
