ASSIST Recommendation Provides New Evaluation Metric for Parking Lot Luminaires

Parking lot and outdoor luminaires are a rapidly growing market for the LED lighting industry, and many LED-based outdoor luminaires have entered the marketplace with claims of significant energy savings and life-cycle cost reductions compared to traditional luminaires. However, some of these LED systems are not realistically able to meet the requirements of good outdoor lighting, and no simple method exists to evaluate and compare the performance of outdoor lighting systems before selection and installation.

To help outdoor lighting designers and specifiers make optimum luminaire choices, the Alliance for Solid-State Illumination Systems and Technologies (ASSIST) has published a new volume in its ASSIST recommends series about parking lot lighting. The issue "Recommendations for Evaluating Parking Lot Luminaires" describes a new, alternative metric for evaluating parking lot luminaires based upon how well they cater to the application's requirements. The metric was developed through previous research by the LRC and builds upon the concept of application efficacy.

The volume is available for free download from the ASSIST Web site.
