The analysis of illumination engineering is vital not only to understand the principles of light control as enforced to interior lighting architecture like domestic and factory lighting but also necessary to understand outdoor applications such as highway lighting and floodlighting. In this modern era, electrically originated light is preferred to the other source of illumination, due to an account of its steady light output, low cost, cleanliness, ease of control, and reliability. The most excellent illumination is that it produces no anxiety in the eyes. Besides its decorative and esthetic facet, good lighting has a rigorously functional value in lowering the fatigue of the workers, protecting their health, rising production, etc. The science of illumination engineering is, therefore, become major important.

1. Elucidate illumination
2. Discuss the properties of good illumination
3. Illustrate the various terms used in illumination
4. Identify the relation between various units
5. Identify the measurement of light intensity
6. Discuss the laws of illumination
