Other versions: The Valenti Hebi table lamps were also made as a clamp lamp and exists in many colours. A table lamp, the Hebi Tavolo was also made, you can find it over here. In the 1980s a version named Hebi Alo was also produced. It has a 12 volt halogen bulb, aflat lampshade and an external transformer.


Hebi is the Japanese word for snake. The flexible metal tube is covered in plastic and can be twisted in every direction and the lamp shade can be rotated as well.

A lamp with an unlimited flexibility of positions. It uses almost exclusively already existing components such as the PVC tube, usually used in wall cavities to carry electrical cables.

Versions and colours changed during the years. The first editions have a big VLM-switch model 475 designed by Achille Castiglioni and a aluminium tube with a internal hexagon socket-head screw on the end. Where the wiring starts is in later versions “Valenti Made in Italy” moulded in the rubber.
More recently produced models were cheaper made and didn’t have the aluminium end tube; it became a plastic one. The name Valenti appeared in the middle on the flex tube.


Valenti was founded in Milan in 1929 as a metalworking company.  It became one of the most important companies of the Italian design movement under the leadership of the brothers Diego and Renzo Phigi.

Famous lighting produced by Valenti: Medusa floor and table lamp, design Olaf Von Bohr in 1968. The Pistillo flush mount/wall lamp, design Studio Tetrarch in 1969. The Medusa lamp was also sold under the Ecolight label.

Ecolight was a brand of the Valenti company. Ecolight was born in 1968. Many lamps were sold as Valenti and also as Ecolight. This Pillola lamp was sold under both names. Ditto for the Squadra wall lamp. The business was run by Carla and Laura, the daughters of Renzo.

In 2013, SP light and Design was born from the desire of Carla and her husband Luciano to pursue the family business, joined by their eldest daughter, Eleonora.

SP light and Design still sells some of their design icons such as the Pistillo and Pistillino wall lamps and the Medusa floor lamp. Today (2017) the Hebi lamp is still in production. Available in red, black, white. You can find it on their website.
