Looking for a design halogen for some time I discovered Cadmo designed by Karim Rashid on behalf of Artemide. The latter is the interest to be a conventional halogen with its powerful lighting but also to give a light atmosphere with its low system. The form is superb, everything is free of charge. Conclusion it will be in my Office very quickly!
You can find it at made in design around €1000 (it depends on the version you choose).
