Wow. That's what we said when we saw these pendant lights from Bocci.
The 14 series pendant lights are designed by Omer Arbel, whose background in architecture is shown in the way the lights affect the spaces around them. The series consists of small cast glass pendants, 4" in diameter, that hold a 10-watt halogen bulb. They're suspended using cable so that they appear to be bubbles floating. Imperfections in the glass spheres add to the effect.
Unica Home sells the 14 series. While these fantastic lights are not inexpensive (from $305 for one, to $8,820 -- yes, you read that right -- for 25), if you lived in a space where they could be really showcased... well, we bet that then everyone who walked into your home would say wow, too.
