Phos B Corp

Phos is a British lighting manufacturer that enriches minds and spaces through precision-engineered instruments. Based in Hertfordshire, we have been crafting light since 1883. Across five generations, our focus has stayed the same. We design light that helps people feel present, calm and connected to the spaces they inhabit. We believe light should serve both beauty and wellbeing. Our products combine tight optical control, sustainable practice and meticulous finishes that protect atmosphere and elevate design intent. We manufacture over 90 percent of our components locally, supporting quality, ethics and circularity. As a certified B Corp and winners of the King’s Award for Enterprise, we are committed to doing business in a way that benefits people and planet. We work with architects, interior designers and developers in more than 40 countries. From hospitality and residential projects to workplaces and cultural spaces, Phos is trusted where atmosphere matters most. Light Tribe by Phos is our research and education platform. It explores how light influences human emotion, health and behaviour, and helps design teams create environments that feel good to be in.
