IES Publishes Two New Outdoor Lighting Standards

The Illuminating Engineering Society of North America (IES) has published two new recommended-practice standards for outdoor lighting that are of relevance to SSL because of its growing dominance in outdoor lighting applications:

IES RP-20-14 (“Lighting for Parking Facilities”) is intended to optimize pedestrian and vehicle safety as well as energy conservation, and also addresses light trespass. It covers outdoor lots and roofed garages and is intended to guide new installations but not to be applied to existing installations unless their lighting is updated with the latest technology.
IES RP-33-14 (“Lighting for Exterior Environments”) focuses on such issues as light trespass and sky glow and is intended to help lighting designers and specifiers determine the proper lighting zone specifications for particular applications.

Electronic copies may be purchased online through the IES store.
