The 'm' designation for this edition of Bocci's 14.1 pendant refers to the mini size of the canopy, which measures just over 2.9cm in diameter and 1.3cm deep, making it very subtle and essentially disappearing into the surface it is placed on. It is a beautiful, low-voltage pendant light designed to achieve a unique and exquisite atmospheric composition. Each 14.1m is a molten glass sphere that articulates into a canopy that can be either a single core or not, depending on the needs of your lighting design. The light they give off interacts with the natural bubbles and imperfections of the molten glass to produce a glow reminiscent of small candles floating within spheres of water. Molten glass is an organic process, imperfect by nature, and each 14.1m is handmade, making each piece unique. These lamps are suitable for both commercial and residential use. Long-life Xenon bulbs included. Not dimmable with LED spotlights.
