Not all nighttime environments are the same; therefore, outdoor lighting should be tailored to the specific tasks required. The newly updated standard (ANSI/IES RP-43-25 Recommended Practice: Lighting Design for Outdoor Pedestrian Applications) introduces a refined framework for defining the expected luminous environment (aka, lighting zones) associated with common nighttime tasks. Lighting zones can then be used as an essential tool for balancing visibility, environmental stewardship, and the human experience at night. This webinar explores the intent behind the new lighting zone definitions and how they apply to the outdoor environments we create. From urban centers to rural landscapes, we’ll examine how lighting zones shape design decisions, influence light levels, and support responsible use of light at night. Whether you’re designing, reviewing, or setting policy, this webinar will help you translate RP-43 into practice. All live attendees will receive a 25% discount on ANSI/IES RP-43-25.
