Product Description
Bulbo 57 is an iconic design from the Achille Castiglioni collection. Initially designed for the Xi Triennale in 1957, the oversized industrial bulb houses a striking filament — a glorious piece of industrial design for contemporary homes. Recently re-released for 2020, Flos have reproduced the classic filament in tungsten with an LED source, preserving the same colour and intensity as the original with reduced energy consumption.
Materials & Finishes
A bulb-shaped lighting unit made of blown borosilicate glass, with good shock resistance properties and excellent transparency, due to the reduced thickness of the material. The led filament is held in position by a molybdenum structure incorporated in a thin tube, also made of borosilicate, which is used in turn to extract the air and therefore prevent any internal condensation build-up. The filaments which convey the power are housed in a dedicated cable gland designed to satisfy the safety regulations and standards. The light source consists of a 225 mm long flexible micro-led filament, using customised electronics which can handle a light flow of 210 – 450 lumen, using the most common Triac dimmers. Luminous flux is in proportion to the voltage for each lighting fixture. The light temperature of 2200°K was selected to replicate that of the traditional incandescent lamp. The same applies to the high CRI (95), which guarantees a high-quality standard of chromatic performance.
