Lamp in white opaline glass, Velella model designed by Achille and Pier Giacomo Castiglioni for Flos in 1967. Discontinued model, purchased in 1974, original and working, glass in perfect condition. Velella is a lamp with mixed light, incandescent and fluorescent. With the central reactor, it supplies three types of illumination: white light, spread in all directions, by switching on the fluorescent source; warm light, directed downwards, with light diffusion towards the opaline surface of the glass, by switching on the incandescent source; mixed light, by switching on the two light sources at the same time. The chrome-plated lamp holder is foxed with age, but can still be unscrewed. Dimensions: height 19 cm, diameter 40 cm.
