Watt Stopper/Legrand announces the launch of RoHS-compliant commercial occupancy sensors as part of the company’s ongoing commitment to the planet. Specifiers, building owners and contractors who select these lighting controls can be assured that they are helping reduce the amount of hazardous waste that will enter the environment, in addition to achieving energy savings.
Watt Stopper/Legrand’s Isolé plug load controller provides a convenient way for building managers to prevent wasted energy from a wide variety of electrical devices in private and modular offices. Isolé couples a personal occupancy sensor with a surge-protected power strip to turn off unneeded devices when a space is vacant while also protecting expensive equipment. It is the only occupancy-based plug load controller available.
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.
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.
Special residential vacancy sensors from Watt Stopper/Legrand include LED nightlights for added comfort, convenience and safety, as well as energy savings. These sensors offer many benefits to homeowners and are perfect for retrofits or new construction.
For years, Lander University relied on a programmable relay-based system installed in the mid 1980s to provide energy-saving scheduled control of lighting and equipment for its most vital buildings. While the system, which controlled the Learning Center, Cultural Center, Student Center and Athletic Complex, had initially served its purpose, the controls had become antiquated and unreliable. After experiencing numerous disruptions to classes and events, engineers at the state university in Greenwood, S.C., set out to research replacement options.
Engineering Services Department personnel priced equipment and installation costs for a variety of solutions and were delighted to learn about Watt Stopper/Legrand’s unique ability to upgrade older GE panels, retrofitting them with new control engines. For less than ten percent of the cost of a new system, they could refurbish the existing panels and enjoy the benefits of a sophisticated, modern control system. The university could significantly extend the life of its capital equipment and avoid sending materials to a landfill. Additionally, the upgrade would take much less time than a full replacement.
