Luisa T1 glass table lamp with white metal frame The beautiful lampshade of the Luisa T1 table lamp, which is made of mouth-blown glass and almost completely encloses the frame, sits on a matt white lacquered frame with three small feet. In the centre of the frame, which extends through the entire lampshade and protrudes only slightly at the top and bottom, warm white LEDs have been installed behind a cylindrical, opal white diffuser, which allow the satinised diffuser to shine evenly and, in addition to the cosy light colour, are characterised by very good colour rendering (Ra >90). Mouth-blown glass shades are the hallmark of the manufacturer of this Luisa luminaire series. Prandina lights is a manufacturer based in Italy whose products are highly recognisable thanks to their unique, mouth-blown lampshades. Sergio Prandina founded the company in 1982, which works with numerous world-renowned architects and designers and sets the highest quality standards for its products. The Luisa series of lamps is a design by Gauzak, a Spanish design studio founded in 2011 with offices in Barcelona and Palma de Mallorca.
