Clessidra 20°+20° Outdoor is a lighting unit designed by Antonio Citterio for Italian Flos in 2011. The lamp has a body made of cast aluminum with a powder-coated finish and a diffuser in acrylic plastic and a cover made of nylon. The fixture has a humidity rating of IP55 and includes a backplate with a brown finish to cover the checkbox. Clessidra is available for both indoor and outdoor use. The right model is made for outdoor use and is available in dark brown or dark green lacquer. It includes high-efficiency lenses that are specially designed for night vision. The power supply has several voltages (100-240 V) and is built-into the frame. Clessidra is an attractive alternative for illuminating halls and outdoor areas. Clessidra means hourglass in Italian, from which Citterio has taken his inspiration. Clessidra 20°+20° Outdoor is a modern wall lamp for outdoor use with upward and downward light with a distribution of 20°, hence the name. Works well in both large and small spaces.
