Light pollution, obtrusive light, or nuisance light affects people, animals and plants, it wastes energy, and it is completely avoidable. The ILP’s world-renowned guidance on the reduction of obtrusive light was updated in 2020 and in our free CPD session, we invite all lighting engineers, designers, consultants and manufacturers to:

• See Allan Howard BEng (Hons) CEng FILP, panel chair, present the latest GN01 Guidance Notes for the Reduction of Obtrusive Light 2020.
• Understand Table 4 and follow an example approach for calculating light intensity.
• Learn from Emily Bolt BEng (Hons), to discover practical information on what type of products to apply in what situations, available from many manufacturers.
