The Backlight-Uplight-Glare (BUG) rating system has been proposed as a metric for evaluating luminaire photometric output with respect to issues surrounding exterior environmental sensitivity based on the Luminaire Classification System (LCS) infrastructure established in IES TM-15�07. The BUG rating system was adopted and issued as Addendum A to IES TM-15�07. The proposed original values for the BUG system have since been modified to decouple the uplight and glare ratings based on feedback received during the public review process, but the basic infrastructure of the BUG system remains unchanged. The results of the analysis examining the impact of decoupling on the BUG ratings of various luminaires showed that the vast majority, 78 percent of �U� ratings, 90 percent of �G� ratings and 94 percent of combined �UG� ratings, will remain the same.
