Description
Bulbo 57 is a suspension lamp designed by Achille & Pier Giacomo Castiglioni (Flos).
When designing means breaking down or deconstructing, and shapes are forged through observation of what already exists – these are some of the commandments put in place by the Castiglioni brothers. In the case of Bulbo the rule of simplifi cation is very clear. This lamp is a synthesis of redesign and ready-made: a large industrial bulb without its screw cap and with a shortened neck to take the shape of a bubble. The classic fi lament inside becomes its distinguishing feature, both decorative and illuminating. The light source itself highlights the technical design that characterizes this lamp, and also makes it work.
Bulbo was designed by Achille and Pier Giacomo Castiglioni for an installation at the XI Triennale in Milan in 1957.
When one lamp was connected to others in a series for this exhibition, the light output drastically reduced and the internal fi lament turned a reddish hue, giving off a low-intensity, warm ambient light. The 2019 edition by Flos reproduces its fi lament in tungsten with an LED source, preserving the same color and intensity of the light as in the original.
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.
