Valgustusdesigns

Valgustusdesigns is a Baltic-based lighting design practice focused on architectural and interior lighting for cultural, civic, and commercial spaces. Based in Tallinn, Estonia, the firm operates across Northern Europe, delivering daylight-integrated, energy-efficient lighting concepts and control systems.

Founded in 2012 by architect Katrin Mägi and lighting designer Mikko Kallas, Valgustusdesigns developed from collaborations on public-building projects and evolved into a specialist practice with a multidisciplinary team of designers, engineers, and technicians.

The studio emphasizes human-centric lighting, glare control, and sustainable design. Its work combines daylight harvesting, tunable white LED systems, and smart controls to adapt to different activities and times of day. Technical approaches include daylight simulations, BIM workflows, and collaboration with manufacturers to specify modular, durable fixtures.

The portfolio includes cultural venues, educational facilities, and public spaces, with projects such as a Tallinn library, a regional gallery in Tartu, and a university atrium in Vilnius. The firm is noted for seamless integration of luminaires with architectural form, warm ambient layers, and precise task lighting.

Valgustusdesigns has contributed to industry discourse through case studies, design reviews, and participation in design awards. The practice emphasizes local craftsmanship, transparent timelines, and client education on lighting strategies.
