Wallenius Water AB and LightLab Sweden AB sign commercial cooperation agreement

The companies have for some time discussed the possibilities of developing
mercury-free UV lamps for fluid purifying applications, based on LightLab’s
technology platform. Technical pre-study results from 2014 in combination with
the companies’ joint assessment of the market potential have resulted in a
decision to jointly proceed into a next phase.

Wallenius Water and Lightlab will therefore, as the next step, cooperate around
the development and performance evaluation of prototype lamps for the UV area.

“Taking the next step in the cooperation with a Swedish world-leading
environmental technology company, and one that recognizes the potential of our
technology, is logical and exciting,” says Jan- Erik Lennefalk, CEO of LightLab.

“Wallenius Water is driving in the pursuit of sustainable alternatives to
mercury-based UV lamps. We believe in the opportunity to realize this vision in
cooperation with LightLab, and look forward to our joint project,” says Torkel
Elgh, President of Wallenius Water.
