Phos
Phos is part of The Cadisch Group, a family of engineering companies founded in 1883 and spanning five generations. With deep expertise in metals and a history of supplying industries from aerospace to automotive, the group has built a reputation for excellence and even earned a Royal Warrant. This heritage, combined with cutting-edge LED technology, forms the foundation of Phos lighting – a range of luminaires that are functional, customisable, and beautifully engineered.
The mission of Phos is clear: to redefine how artificial light sources are engineered to replicate natural light. Every product is designed to be compact, sustainable, and modular, with a focus on quality and longevity. At the core of Phos lighting is the belief that light should enhance architecture in harmony, felt but not seen. This philosophy drives the creation of some of the smallest yet most powerful luminaires in the world, protected by over 14 patents.
Integrity, enthusiasm, and diligence guide every decision. Phos is committed to sustainability, producing all components in the UK from locally sourced, 100% recyclable materials. Each fixture can be crafted from any metal alloy and finished in an unrivalled palette of options, from anodised and plated surfaces to raw brass, copper, bronze, or marine-grade stainless steel. This attention to detail ensures every luminaire blends seamlessly into its environment or makes a bold design statement.
The Genesis engine represents a breakthrough in light quality. After years of research, Phos developed proprietary chip, phosphor, and packaging technology to create full-spectrum natural light indoors. With a CRI of 98+ and TM-30-15 ratings (Rf 98 / Rg 101), Phos delivers unparalleled colour rendering that elevates interiors with clarity and vibrancy.
Phos lighting embraces biophilic design, echoing humanity’s innate connection to nature. Shapes, textures, and finishes reflect natural influences, while the light itself replicates the purity of daylight. As a certified B Corp, Phos demonstrates its commitment to local manufacture, recycling, and lifetime project support. Every fixture is built to be repaired, restored, and regenerated, ensuring sustainability is embedded in every stage of its life cycle.
With innovation, craftsmanship, and sustainability at its heart, Phos lighting represents the closest step yet toward bringing natural light indoors.
