Adaptive Wall Packs at UC Davis

Last June UC Davis replaced 101 static HPS and MH wall packs with adaptive LED wall packs by Philips, equipping them with outdoor motion sensors by WattStopper and networked controls from Lumewave. Along with streetlights and post-top luminaires, the wall packs were incorporated into the Adaptive Campus Control System at UC Davis, via an RF network that provides campus-wide lighting control.

Adaptive LED Wall Packs

Wall packs offer an effective means of illuminating building perimeters, bolstering security and aiding wayfinding, but many are limited in terms of their efficiency, with minimal or nonexistent cutoff. Moreover, because wall packs typically operate in areas with low occupancy rates, they often waste energy fully illuminating vacant spaces for hours at a time every night.

In 2012, UC Davis upgraded its exterior lighting as part of the university’s Smart Lighting Initiative. Wall packs on campus, like other exterior lighting fixtures, were retrofitted with dimmable LED sources, motion sensors, and wireless controls. This allowed the units to be incorporated into an adaptive campuswide lighting control system. The system offers an intelligent, networked approach to lighting and energy management, with improved lighting quality and optimal energy efficiency.

Advanced LED Downlighting System

This technical brief deals with the issue of existing LED downlight products that fail to live up to expectations, providing poor light distribution, glare, and low system efficiencies. The solution is newly designed downlights that use LEDs to their full potential while maintaining the features and functionality that have made them popular.

Evaluation of Xenon Lighting

Due to the potential use of xenon lamps in outdoor applications, CLTC in collaboration with PG&E, developed an evaluation and testing program for xenon technology used in general illumination, outdoor applications. The research included under this project informed utilities about the performance and reliability of xenon lamps in these applications as compared to Light Emitting Diodes (LED), induction or other appropriate parking and area lighting solutions.
