Watt Stopper/Legrand has developed the LS-301 Dimming Photosensor, carefully combining features for optimal performance and ease of installation and use. At the heart of the device is the groundbreaking sliding setpoint control algorithm pioneered by Watt Stopper/Legrand. The LS-301 also employs a handheld setup remote to facilitate quick and convenient commissioning.

Watt Stopper/Legrand introduces the new fixture-mounted FD-301 dimming photosensor. Lighting fixture manufacturers can easily integrate the FD-301 during production so fixtures arrive at the jobsite with the control pre-wired, adding value and saving contractors’ time. Commissioning, too, is fast and simple. Once operational, the photosensor provides precise and reliable energy-saving control, dimming 0-10 VDC ballasts in response to available daylight. Integrating the device into the fixture also improves aesthetics, reducing the number of items on the ceiling.
A Square D® Powerlink® whole-building lighting control system can now be seamlessly integrated into a commercial building automation system with the incorporation of the Building Automation and Control network (BACnet®) communication protocol into Powerlink intelligent lighting control panelboards. Incorporation of BACnet into Square D Powerlink panelboards significantly reduces the cost and challenges normally associated with incorporating a lighting control system into a comprehensive building automation platform. At the same time, it makes it easier for a building owner or facility manager to access information about all of a building’s systems, including lighting, in order to maximize both energy and cost savings.
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.
