The first two publications listed below are designed to help homeowners, contractors, builders, and others understand the best practices for directional lighting (e.g., downlights, accent lights, and track lights) and what to look for in an LED-based directional lamp or light fixture. The last document is written for fixture manufacturers and provides recommendations for testing directional lighting fixtures, regardless of light source.
