Diego Sáez Ibarzábal founded Inlucem Architectural Lighting Design in 2014.
He graduated in Architecture from ETSAM, Technical University of Madrid, Spain, in 2006, and later completed a Master in Architectural Lighting at the same school in 2010.
Diego brings together two complementary disciplines that rarely operate as one.
His work integrates architectural intention with technical precision, ensuring that lighting is never an afterthought but a fundamental layer of spatial design.
His understanding of construction began much earlier. Growing up as the son of a Civil Engineer who ran an electrical and lighting company for over 30 years, Diego developed an early awareness of how design meets reality on site. Working as an electrician during his summers gave him first-hand experience of installation challenges, coordination with trades, and the practical constraints that shape every project.
This background defines his approach today.
Every lighting solution is delivered with the vision of an Architect, the knowledge of a specialised Lighting Designer, and the practical eye of an experienced electrician who understands what it takes to make design work on site.
For Diego, light is not simply a technical layer, but a material that shapes how we feel within a space. A designer with a strong technical foundation, he approaches every project with precision, yet his true focus remains on atmosphere, emotion, and the human experience of architecture.
This is the foundation of Inlucem’s work, transforming ideas into built light, and shaping how architecture is truly experienced.
With a background in architecture and more than a decade leading Inlucem Architectural Lighting Design, Diego approaches every project with a deep understanding of spatial composition, proportion, and materiality. Light is treated as an integral architectural layer, ensuring coherence between design intent and built reality.
Holding a Master in Architectural Lighting and years of specialised practice, Diego designs layered lighting systems that balance performance with atmosphere. Each solution is developed to control contrast, minimise glare, and support wellbeing, shaping environments that feel natural, intentional, and alive.
Since founding Inlucem in 2014, Diego has been guided by a clear belief, that good lighting transforms how people experience their homes and workplaces. His passion for light and architecture is ultimately about people, how they feel, how they move, and how they live within a space. The impact of lighting on everyday life drives him to work with care, precision, and commitment in every project.
Because when light is right, life within the space feels right.
At Inlucem, we don't just illuminate areas; we bring them to life.
Our journey began with a simple yet profound realisation: light is not just a utility but a vital instrument in crafting ambiance, mood, and experience.
Lighting is most effective when it is integrated into the architecture from the very beginning. If you would like to explore how light can shape atmosphere, support wellbeing, and enhance the way your space is experienced, we would be pleased to guide you.
