Diligence and Precision
Unfortunately over lighting is a common practice when it comes to outdoor lighting and PLG practices a system of photometric analysis to avoid it. Outlined by the Model Lighting Ordinance (http://www.ies.org/PDF/MLO/MLO_FINAL_June2011.pdf) created jointly by the Illuminating Engineering Society (IES), a benchmark of lighting practices,and the IDA, PLG’s photometric analysis system ensures that light is only placed in the exact space and in the amount required for each individual location. By taking the initiative and sending engineers into the field for site surveys and light readings, PLG can confidently claim that our proposed fixtures will meet IDA standards.
Blue Light creates more light pollution than any other type of light, it has also been shown to cause harm to human and wildlife health. By producing LED options with lower then 3000K color temperature, PLG is on the forefront of preventing blue light emissions. Since 2010 an IDA published paper provided scientific evidence on the hazards of blue-rich white light sources. “The case against blue light is well founded with regard to discomfort glare, circadian rhythm disruption, light scattering skyglow, and biological system disruption in wildlife”(http://darksky.org/lighting/lighting-basics/)
In addition to IDAs paper the American Medical Association (AMA) released a paper further outlining blue-lights harmful effects in the summer of 2016. (https://www.ama-assn.org/ama-adopts-guidance-reduce-harm-high-intensity-street-lights)
