I love these light bulbs by Pieke Bergmans. Select 'work' then 'light bulbs' to see more images including the fabrication process.
From apartment therapy:
Pieke Bergmans' series of one-of-a-kind crystal LED lamps for Royal Leerdam Crystal and Solid Lighting are what the designer calls "light blubs." And what exactly is a light blub?
"The answer is simple," says the young Dutch designer. "It is a light bulb that has gone way out of line. Infected by the dreaded Design Virus, these Blubs have taken on all kinds of forms and sizes you wouldn't expect from such well behaving and reliable little products."
Bergmans calls her one-of-a-kind light sculptures "unlimited edition," in that that each unique piece is made using an industrial process she developed that can be repeated until the end of time.
