21.7 is a clustered configuration of seven 21 pendants hung from a round canopy. The pendants are designed to hang in a random configuration at times clustering and grouping together and others trailing off. The result is an ambient installation or field of light. The pendant drop lengths on this fixture are adjustable up to the specified maximum.

Inspired by the sporadic, discordant arrangement of barnacles on a rock surface, the 21 is fabricated from thin sheets of porcelain wrapped around a trumpet shaped borosilicate diffuser. Each diffuser houses a low voltage lamp. A strong contrast is established between the organically distributed soft light passing through the white porcelain skin and the sharp, crisp light passing through the borosilicate glass diffuser.
