About Us

OSIN is a company born here in Aotearoa. Being from a small island nation, Kiwis grow up with a uniquely intimate connection to the great outdoors. It is this relationship with nature that inspires us. OSIN has collaborated with leading technologists and scientists to bring the benefit of the outdoors into indoor space. Our name 'OSIN' is an abbreviation of outside-in.




Our Story

After successfully running a lighting business for over fifteen years, entrepreneur and father of two, Ralph Booth, began exploring the connection between light and human biology. He was driven by a desire to understand the effects of an indoor lifestyle on our body-clock and to develop a solution to harness the power of light to help people live healthier lives.
