Light is made from wool and recycled bottles

Lyktan Hood

Swedish lighting manufacturer Lyktan has unveiled a luminaire made predominantly from wool and recycled PET bottles.

The Hood is designed with a strong sound absorption element for schools, universities and open-plan office.

The company says that by making the light it is helping to avoid the considerable waste from the Swedish wool industry.

‘The thick fleece of the sheep is sheared twice a year, but barely half of the wool is used,’ a spokesperson for the company told the press. ‘Over 50 per cent of wool is burned or discarded in Sweden, while a significant amount is imported from abroad. Through our work with Swedish wool as a material, we hope to contribute to a positive change’.

‘We got the idea when we needed a flexible light source and sound absorbent above our conference table in our new studio as it’s an open-plan and with a very high ceiling’ says the designgroup Form Us With Love, which worked on the luminaire for Lyktan.

The designers say that Swedish-produced wool is a ‘climate-smart’ natural material with many positive characteristics. It is durable, malleable, biodegradable, and also fire-resistant thanks to its high content of nitrogen and water.

‘All of these qualities made wool the obvious choice for us,’ says the practice, ‘and using Swedish wool as a raw material quickly became one of our main priorities.’

Its modular structure means that Hood can grow according to need. Mounting of the screen sections is done with a single screw.

The wool version of Hood consist of 55 per cent wool from Swedish sheep combined with 45 per cent bio-degradable melting fibre from recycled PET-bottles.

In model 1200×1800 there are two light units. The version of Hood in partly recycled polyester consist of fibres from recycled PET bottles and virgin polyester fibre. The recycled content is up to 80 per cent depending on the specific colour.

Another version has a shade of moulded polyester and wool felt, with the latter partly recycled

In all models, there is a light unit in each suspension point. Light units are connected in one line and the power supply is via the first light unit in line.

The frame is in black lacquered structure aluminium and the diffuser is in opal acrylic.
