These six lighting professionals, hailing from diverse backgrounds and locations, have demonstrated exceptional skill, knowledge, and commitment to the field, and their achievement marks a significant milestone in their careers.

The certification process, governed by the Certified Lighting Design Commission, assesses one’s ability to operate as a lead architectural lighting designer professionally and proficiently by considering a person’s imaginative, technical, and professional responsibility skills.

As the first evidence-based certification program in architectural lighting design in the world, obtaining the Certified Lighting Designer (CLD) title denotes that these individuals have proven track records of design excellence and have successfully validated their skills through a rigorous assessment process that defines high standards of professional practice.

“We are incredibly proud of this year’s CLD recipients,” said David Becker, Chair of the Certified Lighting Design Commission. “Recognised by this global benchmark of performance, we have no doubt that they will continue to make significant contributions to the field, elevating the quality and impact of lighting in spaces of all types.”
