A database of results has been created to help engineers compare the performance of their own projects to the glow, trespass, and glare levels measured at nighttime lighting applications located across North America and Europe.
Bullough says a more extensive, continually growing database updated by the lighting community would be invaluable for making systematic progress in reducing light pollution.
Based on the 125 sites examined, LRC scientists have developed provisional limits for glow, trespass, and glare, offered as starting points for subsequent discussion among all stakeholders in nighttime lighting, according to Rea.
OSP can be used by lighting engineers immediately, particularly for the investigation of glow and trespass (glare analyses are more complex to perform and current commercial software does not readily allow them), and can help users compare several lighting design alternatives for the same site.
"This project began in 2005 with leading manufacturers approaching us for an objective and unbiased assessment of light pollution, and as a result, we are pleased to share this new, comprehensive tool that brings much-needed balance to the discussion," said Rea.
