SLL LightBytes Online


Following developments relating to the spread of Coronavirus (COVID-19), the decision was made to cancel the remaining face to face events in the 2019-20 LightBytes series.

In order to help you maintain your CPD remotely, and to deliver the informative, peer reviewed content the Society has developed the SLL LightBytes Online webinar series instead.

Watch recordings from all four of the SLL LightBytes Online webinars:


The 2019-20 series focuses on light and wellness, with presentations divided into four overarching sessions; 

LightBytes Online consisted of four webinars, each focusing on one of the sessions above, with peer reviewed presentations delivered by the following speakers; Dr Eleonora Brembilla, Research Associate in advanced building daylight modelling; Richard Caple FSLL, Marketing & Applications Director for Thorlux; Roger Sexton FSLL, Vice President Specifier Support for Xicato; and Graeme Shaw MSLL, Technical Applications Manager for Zumtobel.

Each webinar included a live Q&A with the speakers.

Whilst there is still a very apparent need for further research and conclusive evidence concerning circadian lighting or the application of lighting for wellness, there is no substitute for daylight in relation to the stimulation of the circadian system and support of human health.
