I would like to introduce you to the miniature work of my friend Francisco del Pozo Parés in Spain : in my opinion he makes the finest contemporary lamps... next to all his other creations, which can be viewed at http://www.artmajeur.com/miniarquitect/
Here a selection..
All bulbs are 12V bi-pin of 30 or 60 mA (in the gallery this information, as well as the materials is included for each lamp, although in Spanish). They are mainly made of brass and resin
