BUG Rating System and Nighttime LED Outdoor Lighting
The BUG Lighting Classification System is a useful way to measure the performance of luminaires at night. Developed by the Illuminating Engineering Society (IES) and the International Dark-Sky Association, the system is used to evaluate any outdoor luminaire. It was first added to the Luminaire Classification System (LCS) in 2009, replacing the previous system that was primarily for streetlights.
