The Alliance for Solid-State Illumination Systems and Technologies (ASSIST), a program of the Lighting Research Center (LRC) at Rensselaer Polytechnic Institute, has released a publication that proposes a new method of evaluating human perception of directly observed light source flicker. The publication, ASSIST recommends…Recommended Metric for Assessing the Direct Perception of Light Source Flicker, provides specific measurement procedures and calculations to objectively determine whether the amount of flicker from a light source is above or below the threshold of human perception. The metric is applicable to any waveform shape and frequency and is based on peer-reviewed laboratory and human factors experiments.

Imagine a future where our homes, businesses, and cities are powered completely by the most abundant and unlimited energy resource on earth: the sun. Harry Verhaar, the Philips Lighting Head of Global Public and Government Affairs, is doing just that by creating a blueprint for a future lit by solar-powered, energy-efficient lights. In 2003, Verhaar started the global initiative to phase out inefficient lighting technology in favor of LED lights and has since led Philips to become a world leader in the solar-LED market. With the recent release of PHILIPS NEW LINE OF CONSUMER SOLAR-LED LUMINAIRES, we spoke with Verhaar about the future of solar light and how Philips is playing a role in such an important endeavor.
