The Certified Lighting Efficiency Professional (CLEP) Exam Question Bank is built for that test. 840 original multiple-choice questions. Eight simulated exams. Each one was timed to four hours, the same window as the AEE certification exam. Questions move from fundamentals to specialist items and follow the current CLEP Body of Knowledge, including LED performance, lighting quality and health, controls, audits, photometrics, and financial analysis.

Use the bank to find the topics that will cost you points, then close them before exam day. It is independent preparation from Beyond Smart Cities. It is not an AEE publication, and a practice score is not a pass.

Who is this question bank for?

• Energy managers leading lighting efficiency and retrofit projects
• Electrical, technical, and operations engineers cutting lighting energy and utility cost
• Lighting designers, consultants, and facility teams working in commercial, industrial, institutional, and government buildings
• Practitioners comparing a lighting measure with other efficiency projects and defending the ROI
• Firms that want one standard before staff sit an internationally recognized lighting credential

AEE applicants must meet the current education and experience requirements and complete an approved preparatory course and certification application. 

What the CLEP exam covers

The Certified Lighting Efficiency Professional credential, from the Association of Energy Engineers, recognizes professionals who can specify, assess, and improve lighting for the way a space is occupied and used. That includes new buildings and retrofits.

The exam is open book, four hours, and 120 multiple-choice questions, drawn from 11 mandatory sections. A hand-held calculator is required. Computers, tablets, and phones are excluded. The Body of Knowledge in effect for the current scheme, published in 2025, weighs these topics:

• Language of light and lighting efficiency
• Lighting quantity and quality fundamentals
• Color, visibility, and health
• Traditional lamps, ballasts, and operating characteristics
• LED technology and operating characteristics
• Lighting maintenance and environmental safety
• Lighting controls
• Lighting audits
• Lighting photometrics, reports, and IES files
• Lighting calculations
• Financial analysis metrics and calculations

CLEPs are expected to measure and verify a project, weigh human factors and technology, apply incentives, and compare lighting savings with other efficiency measures.

What you get

Eight complete CLEP practice tests and 840 multiple-choice questions. You can choose to sit a full four-hour simulation or drill one section.

Questions use the situations the exam uses: a space with the wrong light level or uniformity, a retrofit that ignores glare or circadian-sensitive tasks, a control strategy that will not deliver the claimed savings, an IES file or photometric report that does not match the layout, and a financial case that changes when incentives and maintenance are included.

Every answer is tied to the relevant CLEP knowledge area, so a miss tells you what to review next. The bank also includes 151+ CLEP key terminology flash cards and a calculation reference for the engineering and financial formulas used on lighting projects.

What you will be able to do

• Read a space by occupancy and use, then judge quantity, quality, color, and visibility.
• Compare legacy sources with LEDs, including maintenance, safety, and operating characteristics.
• Select controls and audit an existing system without overstating the savings.
• Use photometrics, reports, and IES data, and work through the lighting calculations.
• Build a financial case: savings, incentives, and ROI against other efficiency projects.
• Finish a four-hour practice test under exam conditions.

How to study

Do not sit all eight tests in one week. Take one four-hour test first. No pausing. Score it by topic. That profile is your study plan.

Review only what you missed, using the current AEE CLEP Body of Knowledge and the references from your approved training. Use the middle tests on weak sections. Save the last tests for a full dress rehearsal. In the final days, review terminology, lighting calculations, and the financial metrics you still hesitate on. Then stop.

This bank supports exam practice. It does not replace the approved CLEP preparatory training AEE requires.

Who wrote the questions?

Krishnaji Pawar developed this bank from practice in sustainable design, green building certification (including LEED and GSAS), energy modeling, lighting and energy projects, greenhouse-gas accounting, and environmental management. Beyond Smart Cities publishes it with related training for high-performance buildings and energy credentials.
