CLD exam key facts
- A Certified Lighting Designer (CLD) application needs two to four portfolio projects that show competence in five to seven domains of practice, supported by written responses, exhibits and attestation letters. Source
- The Certified Lighting Designer (CLD) application fee is $110 USD, or $90 USD for professional members of approved lighting design associations. Source
- If CLD reviewers ask for more information on no more than two domains, the candidate has four months to respond; failing three or more domains means reapplying. Source
- New Certified Lighting Designers start with a five-year certification period that needs 70 CLU, then switch to annual recertification. Source

What Practice Test Geeks adds beyond an AI chat for CLD
An AI chatbot can quiz you, but it can't reproduce the exam conditions or keep your record. Here you get:
- A timed, full-length CLD mock exam — 30 questions in 60 minutes with a 50% pass mark, modeled on the official exam's question count and time limit, followed by a score report broken down by exam domain.
- A fixed CLD question bank: the same test every attempt, so your score is comparable from one try to the next instead of changing with every regenerated quiz.
- Progress saved on your device: completed tests, scores and missed questions stay in My Progress, so you can retake only what you got wrong.
- A printable CLD cheat sheet you can print or save as a PDF.
- Free CLD practice tests with the correct answer shown after each question.
