IESSA has as a tenet in the advancement of lighting knowledge. To this end we offer a number of lighting courses from basics to intermediate as well as with those handling specific areas of lighting have been developed.


The Basic lighting Concepts, Vision, Lamps and Colour course is designed to provide persons associated with, or entering into the lighting industry with an understanding of basic lighting terminology and techniques.

The specialised courses are dedicated to various specific aspects of light and covers aspects such as road lighting and maintenance, shop and retail lighting, emergency lighting, and industrial lighting as well as the use of lighting tools such as the ‘Relux computer design program’. These courses range from 1 day to 2 days. The candidates to the courses are recognised with either certificates of attendance or certificates of accomplishment as appropriate.
