Solarly is an interactive light designed to improve the mental health and well-being of young adults at risk of experiencing symptoms of Seasonal Affective Disorder.


Seasonal Affective Disorder (SAD) is a mental illness typically caused by a lack of access to the sun. It is estimated that around 1 in every 3 members of the population in the UK suffer from the symptoms of SAD. Young adults between 18-25 are twice as likely to experience depressive episodes, due to irregular routines and a lack of awareness on the impacts of light on the mind and body. Solarly mimics the benefits of the sun whilst utilising the theology of colour psychology to help stabilise moods. The globe light is controlled by an interactive app, allowing users to create personalised lighting routines to suit their lifestyle, whilst improving awareness. The light is designed to encourage physical interaction with the globe and can be easily moved around living spaces throughout the day. The solution aims to redefine how users experience artificial lighting within the home and to encourage further understanding of light and colour.
