The National Electrical Manufacturers Association (NEMA) has published LC 1-2007 Test Procedure for Compatibility of Hearing Aids and Ultrasonic Lighting Control Devices. This standard provides a basis to evaluate the possible interactions between ultrasonic lighting control devices and hearing aids utilizing a set of test procedures. This evaluation can be used as the basis for specifying performance criteria for both hearing aids and occupancy sensors to eliminate interference.
Universal Lighting Technologies is among the charter members of the new NEMA Premium Ballast Program, which recognizes excellence in energy-saving technology. The program is designed to identify the industry’s most efficient T8 ballasts, including the entire ULTim8® family of electronic ballasts from Universal Lighting Technologies.
Universal Lighting Technologies™ has announced the latest in high efficiency wireless controllable lighting systems with the release of the DEMANDflex™ ballast family and DCL® (Demand Control Lighting) controls. DEMANDflex ballasts feature an innovative wireless control technology to receive commands without the need for extra control wires. These ballasts have the flexibility to have power levels tuned during installation at the circuit level to optimize and maximize energy savings.
Sensor Switch has announced that its revolutionary nLight® Control System has been released and is available for immediate installation. nLight is the first lighting control system to cost-effectively integrate Occupancy-based, Daylight-based, Time-based, and Manual control methods. Requiring no centrally hardwired equipment, nLight provides facility managers with the ability to deliver increased energy savings and occupant convenience via one system, all while lowering equipment and installation costs, to provide a quick return on investment.
NYSERDA sponsored a demonstration project featuring a new Integrated Classroom Lighting System (ICLS) created by Finelite, Inc., a fixture manufacturer, installed as a retrofit into 28 existing classrooms at seven schools and universities. The Lighting Research Center (LRC) assessed teacher and student satisfaction. The result is a design template demonstrated to satisfy audio-visual needs and improve teacher and student satisfaction while reducing lighting power density to an average 0.73W/sq.ft., nearly 50% less than ASHRAE 90.1-2004/2007. Although Finelite optimized the design into an engineered system integrating the company’s light fixtures with state-of-the-art lighting control strategies, the template, if properly designed, can be treated as open source with suitable products from a wide range of manufacturers.
Phoenix Sky Harbor International Airport in Arizona is one of the ten busiest airports in the world. A typical day at Sky Harbor sees 108,887 passengers arrive and depart along with 808 tons of cargo on 1,486 airplanes …
Watt Stopper/Legrand introduces the RD-200 Dimming Wall Switch Vacancy Sensor. By combining a preset dimmer and a sensor, this device helps homeowners enjoy the most pleasing light level for each activity and maximize energy savings. The RD-200, which is the newest addition to Watt Stopper/Legrand’s line of residential vacancy sensors, complies with California Title 24 requirements.
Watt Stopper/Legrand has developed lighting control solutions designed to enhance high-end, modern construction. The company’s newest commercial occupancy sensors incorporate sophisticated design details that make them aesthetically pleasing as well as easy to operate. At the same time, each elegant package is manufactured to withstand the rigors of commercial use; both the robust housing and the control electronics are engineered for longevity.
The Square D® Clipsal® Pascal Automation Controller from Schneider Electric enhances the capabilities of a Square D Clipsal lighting control system by providing expansive scheduling capability and facilitating operation of third-party products from input devices such as keypads and touch screens in both residential and commercial applications. The Pascal Automation Controller is easily installed by an electrical contractor, using standard Cat-5 cable. Third-party products, such as a movie projector, screen, and security or HVAC systems, are connected to the Pascal Automation Controller via its two RS232 ports.
The Siloam Family Health Center in Nashville, Tenn., has employed an energy cost-savings strategy using Square D® Wall Switch Occupancy Sensors from Schneider Electric, allowing allocation of more budget to maximizing patient care. The sensors, which use passive infrared (PIR) technology to detect occupancy, requires a button press to activate lighting in occupied rooms much like a standard light switch. If lights are accidentally left on when the room is vacated, the sensor automatically turns them off after a preset time delay. Forty sensors were co-donated by Schneider Electric’s three Middle Tennessee locations — Nashville, La Vergne and Smyrna — in December 2007, as part of the facilities’ Mission for the Community initiative.
