ExploreAbout this exam
The Lighting Certified (LC) designation is awarded by the National Council on Qualifications for Lighting Professions (NCQLP), a non-profit organization founded in 1991 to serve and protect the well-being of the public through effective and efficient lighting practice. Through a peer-review process, the NCQLP establishes the education, experience and examination requirements for baseline certification across the lighting professions. The credential is aimed at professionals whose work touches lighting - designers, engineers, architects, specifiers, manufacturers' representatives, facility and energy managers, and others who need to demonstrate a baseline command of lighting practice rather than a single specialty. Because the NCQLP frames certification as baseline competence across the lighting professions, candidates should expect the examination to draw on the full breadth of lighting practice - photometry and calculations, lamps and controls, luminaire application, design criteria, codes and energy considerations, and documentation - rather than a narrow product or software focus. The organization also runs an Intern Program: qualified students, or graduates within one year following graduation with a bachelor's degree only, may take the examination as an Intern. Preparation starts with the current LC Candidate Handbook, which the NCQLP publishes with all application materials and detailed information about the examination. Candidates register online, review the posted exam dates and online exam environment, then build a study plan around the handbook's stated content areas, supplementing with hands-on calculation practice and code reading.

What you'll study
About NCQLP LC preparation
Who administers the LC credential, and is this site connected to them?
The LC designation is administered by the National Council on Qualifications for Lighting Professions (NCQLP), a non-profit founded in 1991. This page is an independent study resource and claims no affiliation with, sponsorship by, or endorsement from the NCQLP. Always confirm requirements, fees, and dates directly with the NCQLP before you apply or schedule.
What does the exam actually test?
The NCQLP describes the LC as baseline certification across the lighting professions, established through a peer-review process covering education, experience, and examination requirements. That framing means breadth: expect lighting fundamentals and calculations, sources and controls, application and design criteria, plus codes, energy, and documentation. Use the current LC Candidate Handbook as the authoritative content outline rather than any third-party list.
How do I apply and register?
The NCQLP offers candidates the ability to complete the application online, and publishes a Candidate Handbook containing all application materials and detailed information about the examination. Start with the handbook for the current cycle, then register through the NCQLP site. Confirm eligibility and deadlines there, since this independent page does not track application windows.
Can students take the LC exam?
Yes, through a limited pathway. Qualified students, or graduates within one year following graduation with a bachelor's degree only, may take the examination as an Intern under the NCQLP Intern Program. Note the restrictions: it is tied to a bachelor's degree and to a one-year post-graduation window. Check the NCQLP for current Intern Program terms.
What is the exam format and how long is it?
The NCQLP publishes an overview of the LC examination online environment along with exam dates, and the Candidate Handbook carries the detailed examination information. Those NCQLP materials are the only reliable source for format, timing, and item counts. This page does not restate figures it cannot verify from the source, so confirm format and scheduling details before you plan travel or study timelines.
How hard is it, and what trips candidates up?
Treat it as a breadth exam, not a specialty quiz. The most common failure mode is deep preparation in one area - say, luminaire photometry - while leaving codes, energy compliance, and documentation under-prepared. A second trap is calculation speed: practicing lighting calculations by hand under time pressure exposes unit and geometry errors before exam day. Build coverage across all handbook content areas first, then deepen.
What study order do you recommend?
Read the current Candidate Handbook content outline first and map every listed area to a confidence rating. Then sequence: fundamentals and calculations, sources and controls, application and design criteria, then codes, energy, and documentation. Finish with mixed practice that forces you to switch topics, since real questions do not arrive grouped by chapter.
How does recertification work after I pass?
Lighting Certified certificants must participate in ongoing professional development to maintain the LC designation. Credits earned through professional development activities are reported in 3-year cycles. A minimum of 36 credits must be submitted in each 3-year cycle to maintain certification, or if you have 25 or more years in the lighting professions, only 18 credits are required. Verify current rules with the NCQLP.
Are there retakes if I do not pass?
The NCQLP source material reviewed here does not state a retake policy, so no retake count, waiting period, or fee is given on this page rather than guessed. Ask the NCQLP directly, or check the current Candidate Handbook, which carries the detailed examination information. Plan your first attempt as if it is the only one.
Where can I get official information?
The NCQLP website is the authoritative source for the Candidate Handbook, online registration, exam dates, the Intern Program, and renewal requirements. The NCQLP is reachable at [email protected] and is located c/o the Illuminating Engineering Society, 85 Broad Street, 17th floor, New York, NY 10004. Confirm anything you read elsewhere against those materials.
