In Partnership with ILP

Street lighting design can cause issues with finding suitable positions for installation, understanding the huge range of products available and the issues that need to be accounted for during the design process. This course takes the student on a journey from understanding the nature of light, how we see and the needs of different road users. It examines equipment specifications, luminaire testing and the options that could be considered when retro-fitting lanterns. This course does not include the use of lighting design software, rather, it highlights the aims of issues encountered during the lighting design process.

On completion, students will have knowledge of the issues concerning light, sight, the lighting design process, and product specifications. In addition, this course will focus on design issues and suggest good practice in addressing them and the application of Standards and guidance. 

Course Aim

This two-day blended course consists of a series of on-demand video presentations followed by a half-day online classroom tutorial. On completion, students will have knowledge of the issues concerning light, sight, the lighting design process, and product specifications. In addition, this course will focus on design issues and suggest good practice in addressing them and the application of Standards and guidance.


There are 15 sessions containing a total of approx. 9 hours of on-demand video presentations and access to these will be given for a fixed period leading up to the tutorial. Students will be expected to have viewed all the video content prior to the tutorial. There will be no restrictions for video access during this period so students can fit this in to suit their own lifestyle.
