What is CLD?

The Certified Lighting Designer (CLD) designation is the world's first evidence-based certification in architectural lighting design. The certification process assesses whether an individual can operate as a lead architectural lighting designer professionally and proficiently.

HIGHLIGHTS
 

Why become a CLD?

Designation as Certified Lighting Designer is a global benchmark of performance, making it a valuable addition to your existing qualifications and portfolio of work. Being a CLD sets you apart from competitors by demonstrating to clients that you have a proven track record in meeting high standards of professional practice.

It attracts new business from clients who understand the value of CLD, and confirms your professional status in the eyes of peers, managers, design team colleagues, legislators, and the general public.

How do I apply?

An online application makes the process quick and easy to follow. The application requires the submission of (1) written responses, (2) a portfolio of supporting exhibits, and (3) completed attestation letters.

UPDATE: The CLD Commission now maintains that IALD Professional membership portfolio reviews equate to CLD competence reviews for the seven Domains of Practice. As a result, Professional and Fellow IALD members in good standing can bypass domain evaluation to expedite CLD application, and those who apply before July 2025 will have the application fee waived.
