1 1 Klaus Bollmann President & CEO – Ringdale ActiveLED Developer and Manufacturer of LED Light Fixtures The B.U.G. Rating System

2 2 The original classifications included full cutoff, cutoff, semi-cutoff and non-cutoff. These were designed solely around street lighting applications. These designations were not accurate enough to meet the needs of projects in relation to light trespass, glare and night glow concerns. The Original IES Classification System

3 3 The BUG system was developed by the Illuminating Engineering Society (IES) to make comparing and evaluating outdoor luminaires fast, easy and more complete than older systems. Work on the BUG system started in 2005 when the IES upgraded the original roadway shielding classification system. B.U.G. Ratings – Improved Evaluation Criteria

4 4 ActiveLED Update “B” stands for backlight, or the light directed in back of a mounting pole. “U” stands stands for uplight, or the light directed above the horizontal plane of the luminaire “G” stands for glare, or the amount of light emitted from the luminaire at angles known to cause glare The BUG acronym describes light escaping from an outdoor lighting luminaire in sectors.

5 5 ActiveLED Update B0-U0-G0 means there is no light above 60 degrees. B1-U0-G1 is a rating typical for a commercial parking lot. It may be too dim for a large city center. BUG ratings are not an absolute judge of a light’s requirements

6 6 Allows a specifying engineer to quickly determine the suitability of a light in respect of light trespass, glare or dark sky (up-shine) characteristics. BUG ratings provide backlight output, glare information and indicates how well the luminaire controls uplight. Presents an accurate picture of lumen distribution and overall efficiency of the luminaire Benefits of using the B.U.G. Rating System

7 7 ActiveLED Update Bx-U0-Gx – Must have a “U” rating of “0” resulting in NO uplight The appropriate glare rating is determined by the community. Application of BUG ratings for Dark Skies

8 8 BUG does not apply to residential or indoor lighting. The IDA Fixture Seal of Approval Program can be used to rate residential outdoor luminaires. Application of B.U.G. Rating for Residential and Indoor Lighting

9 9 Glare Control – Before and After Two – 100 Watt ActiveLED Fixtures Two – 1000 Watt Metal Halide Fixtures AFTER BEFORE San Antonio, TX

10 10 Uplight “U” Value – With and Without Acorn Historic Style fixtures with 32 Watt ActiveLED retrofits – 3000K AFTER BEFORE Southwestern University - Georgetown, TX Cutoff Wall Packs and Pole Mounted ActiveLED Lights – 5000K Capital Chevrolet - Austin, TX “U” > 1 “U” = 0

11 Glare Control is better with LED 72 Watt ActiveLED Fixtures 400Watt Metal Halide Fixtures City of Brighton, CO New Old
