Contents and procedures of the examination

You can be examined and certified as an ELE for indoor and/or outdoor lighting. The examination is based on the learning objectives set by ELEA, which cover a total of around 150 individual topics. The spectrum ranges from the basics to lighting planning and design. Not only theoretical knowledge is assessed, but also practical skills.  


The spectrum of topics to be mastered ranges from the fundamentals of lighting technology, electrical engineering, light sources and luminaires to lighting planning and design, the execution, operation and refurbishment of lighting installations and photometric measurements in indoor and outdoor lighting. The detailed learning objectives are binding for all members and are constantly adapted in line with current developments.


The national member societies regularly offer separate examinations for indoor and outdoor lighting. The examination consists of the presentation of a project work to be prepared in advance. This is followed by a technical discussion related to the contents of the project work and the learning objectives. There is deliberately no multiple-choice examination. This is the only way to test the most demanding level of competence defined by ELEA and to confirm it to the candidates.


The Quality Assurance Commission (QSK) of ELEA monitors the uniform and proper conduct of the audits. It is independent and not bound by instructions to the Board of Directors and the Executive Committee of ELEA.


Memorised knowledge is not sufficient to pass an examination for European Lighting Expert Interior Lighting or Exterior Lighting. The learning objectives must be worked out with individual mental effort in order to achieve the required competence.

The learning objectives are therefore classified according to their level of competences to be achieved. The following three levels of difficulty are used for the examination: K1, K2 and K3.


    Reproduce knowledge learnt by heart or acquired through practice: e.g. enumerate, name, describe, point out, distinguish, define, represent, know contexts, laws and applications.


    What has been learned is understood and can be explained, even if it occurs in an unfamiliar context: working on facts and problems, if possible from practice with calculations, graphical representations and explanatory descriptions.

  • K3 : APPLY

    What has been learned must be applied in a new, previously unknown situation; a knowledge transfer to a new application situation takes place: Working on multi-layered problems, such as those that can arise in everyday working life, finding the optimal solution from various possible solutions.

The requirements increase from K1 to K3. The level to be achieved in each case is indicated in the learning content of the respective examination material.


In preparation for the ELE examination, each national lighting company offers a suitable further training programme. In addition to the basics of lighting and electrical engineering, specific content on indoor and outdoor lighting is taught. The theory is reinforced by many practical exercises.

While the examination procedure and contents are identical for all lighting companies, the training programmes offered may differ. Depending on the amount of training required by the participants, this may result in different costs.
