57.37 Cluster is a ceiling lamp from Bocci designed by Omer Arbel in 2013. The lamp has 37 pendants meant to hang in a grouped configuration; the height is fixed at 300 cm. The irregular shape of the lightbulb comes from a manufacturing process in which air spaces of different sizes are fused into a larger glass mass and take the form of a rain cloud. The thick glass makes the air pockets invisible when the lamp is switched off but when lit its interior expands into its own little universe. Each lightbulb measures approximately 10-16.5 cm in diameter and is made by hand so that each one is unique in proportion, size, and shape. The 57.37 is horizontal, so the pendants are suspended from the ceiling with a thin metal cable. For example, they can be placed around a corner or at different distances to create the illusion of suspended gravity. The lamp comes with a round white lacquered ceiling mount.
