The SLL Lighting Design Diploma is widely recognised as the benchmark for lighting professionals.
The Society recognises specialisation in lighting by the award of its Lighting Design Diploma to members who have attained an appropriate standard in light and lighting along with relevant experience. 

The Society also plays a major part in developing educational courses such as the distance learning package by the Lighting Education Trust (LET) and the MSc run by the UCL Bartlett School of Architecture. We also run the series of one day SLL LightBytes in various parts of the country where you can quickly be updated on the latest trends and technology. Mid Career College runs courses on a range of building services subjects.
