MINNEAPOLIS, MN (June 20, 2018) – ONCE®, the world’s leading supplier of research-based agricultural lighting systems, announced today that it had reached a definitive agreement to acquire Germany-based iLOX GmbH (iLOX®) and its Polish subsidiary iLOX® Sp.z.o.o., an innovative lighting developer for agricultural livestock facilities. This strategic alliance integrates two industry leaders into the world’s largest animal-centric lighting company.

“We are extremely excited to welcome iLOX® to the ONCE® family.

Never could I have imagined the impact our work would make in eight years. ONCE® has effectively demonstrated that spectrum and modulation of light can significantly affect animal performance, dramatically reduce stress levels, impact animal behaviors and influence expression of genes in an organism. We have not only changed how the agriculture industry perceives and uses light but we have also become a global authority in animal photobiology and optogenetics. Today, we take it a step further by joining forces with the iLOX ® team to accelerate product development and intensify market adoption while improving our ability to support European-based customers and expanding our sales territories into the Middle East and North Africa.”

“Combining ONCE® and iLOX ® aligns well with the future goals we have previously established,” adds Stefan Warnking, CEO and founder of iLOX®. “We share very similar philosophies and business strategies in focusing on innovative lighting solutions for farmers. The synergy of ONCE® ’s broad IP portfolio of technologies combined with the electronic design capabilities of iLOX® will enable us to create new product offerings and offer science-based lighting solutions to farmers across Europe and the rest of the EMEA region. I am very proud of my team’s achievements and look forward to combining forces with the ONCE® team.”

Under the terms of this agreement, iLOX® will operate as an independent entity within ONCE® group. Mr. Stefan Warnking will remain iLOX® CEO. Financial details of the transaction are not being disclosed.
