A one day seminar introducing you to the substantial changes the new British Standard for Lighting BS5489 has brought.

A new and comprehensively updated BS 5489 Part 1 was published on 31 December 2020 and this CPD seminar will inform lighting professionals of the changes in this important document.

The British Standard provides guidance on all aspects of the design of road and public amenity lighting, including passive safety, sustainability, variable lighting, scotopic and photopic ratios and risk assessments. This educational seminar also includes the draft proposals for EN13201, conflict areas and the latest research on mesopic vision and what action lighting professionals must take.
