What is the BWL doing to identify, plan, and mitigate the risks of not following best practice?

The BWL will consider:

  • Choosing fixtures with minimal uplight while still in accordance with ANSI/IES RP-8-18
  • Using “warm-white” or filtered LEDs (CCT < 3000 K; S/P ratio < 1.2) to minimize blue emission
  • Looking for products with adaptive controls like dimmers, timers and motion sensors
  • Avoiding over-lighting because of the higher luminous efficiency of LEDs
  • Selecting proper distribution patterns suitable for the roadway

The BWL has standardized its streetlight system with a color temp of 3000K. Where possible, International Dark Sky (IDA) fixtures are selected and carry an IDA Seal of Approval. More information can be found on www.darksky.org.
