 WattStopper’s innovative LMLS-400 and LMLS-500 digital photosensors were selected by Building Operating Management (BOM) readers as recipients of BOM’s 2012 Top Products Awards. The photosensors are part of WattStopper’s Digital Lighting Management (DLM) product line, and are specifically designed for easy integration with occupancy sensors and other lighting controls. DLM maximizes energy savings and return on investment (ROI), and meets or exceeds the latest code requirements.
These photosensors comprise the most complete and most flexible range of daylighting control options on the market. Both products include a two-way infrared (IR) transceiver for communication with a wireless configuration tool, and the LMLS-400 features automatic commissioning for either switching or dimming, an industry first. Either sensor can be configured for on/off switching, bi-level or tri-level step switching or step dimming, or continuous dimming for each controlled zone.
A convenient menu-based handheld wireless tool is used for sensor configuration. The wireless tool also initiates the self-commissioning process for the LMLS-400, and prompts users to input light levels in order to quickly commission the LMLS-500. Once the LMLS-500 receives measured light levels for each control zone, it automatically recommends setpoints, greatly simplifying the setup process compared to other open loop daylighting controls.
WattStopper’s LMLS-400 is a single-zone closed loop photosensor that can be installed on a ceiling or in a lighting fixture. The LMLS-500 is a multi-zone open loop photosensor designed to mount on a ceiling or in the light well of a skylight, and control up to three lighting zones. The digital photosensors simply plug into a DLM network and can easily be added, or exchanged for one another, if project requirements change. They are ideal for both retrofits and new construction.
The Building Operating Management Top Products Awards are 100% reader-selected and recognize the most popular manufacturers and suppliers of the year, as determined by building and facility executives who participated in a national survey. Award winners are featured in the January 2012 issue.

 WattStopper has launched two powerful daylighting sensors that allow engineers, building owners and installers unprecedented options when designing, purchasing and implementing daylight harvesting systems. The new LMLS-400 and LMLS-500 may be used for switching or dimming applications, and are specifically designed for easy integration with occupancy sensors and other lighting controls. Both digital photosensors include a two-way infrared (IR) transceiver for communication with a wireless configuration tool, and the LMLS-400 features automatic commissioning for either switching or dimming, an industry first. By developing both open and closed loop control solutions for a full range of dimming and switching control strategies, WattStopper now offers the most complete and most flexible range of daylighting control options on the market.
The LMLS-400 is a single-zone closed loop photosensor that can be installed on a ceiling or in a lighting fixture. The LMLS-500 is a multi-zone open loop photosensor designed to mount on a ceiling or in the light well of a skylight, and control up to three lighting zones. Either sensor can be configured for on/off switching, bi-level or tri-level step switching or step dimming, or continuous dimming for each controlled zone. The digital photosensors are part of WattStopper’s Digital Lighting Management product line, and connect to room controllers and other devices using Cat 5e cables with RJ45 connectors on a free topology room network.
A convenient menu-based handheld wireless tool is used for sensor configuration. The wireless tool also initiates the self-commissioning process for the LMLS-400, and prompts users to input light levels in order to quickly commission the LMLS-500. Once the LMLS-500 receives measured light levels for each control zone, it automatically recommends setpoints, greatly simplifying the setup process compared to other open loop daylighting controls.
The digital photosensors can be easily exchanged for one another if they were not specified correctly, or added to a DLM network or if the project requirements change. Both photosensors detect only the visible portion of the lighting spectrum to precisely measure and control light levels, which prevents over -or under-dimming, and ensures occupant satisfaction.

 NASA's Kennedy Space Center in Florida hosts a ribbon-cutting ceremony for the space agency's most environmentally friendly facility, the Propellants North Administrative and Maintenance Facility in Kennedy's Launch Complex 39 area. From left, are Mike Benik, director of Kennedy's Center Operations; James Wright, deputy assistant administrator for the Office of Strategic Infrastructure at NASA Headquarters; Bob Cabana, Kennedy's center director; Ward Davis, president of HW Davis Construction Inc. in Cape Canaveral, FL, installed a light control system from Lutron Electronics Co., Inc. The Propellants North Administrative and Maintenance Facility is using innovative light control strategies to dramatically reduce energy consumption and maximize the use of available daylight.
“We are thrilled to help NASA achieve net zero energy use in their greenest facilty to-date with simple light control strategies that can save up to 60 percent of lighting energy and increase employee comfort and productivity,” said Andy Wakefield, Government Business Development Director at Lutron.
The light controls at the Propellants North Administrative and Maintenance Facility include wireless wall-mounted controls, digitally addressable electronic ballasts, occupancy sensors and daylight sensors to dramatically reduce energy use. “Many of the office walls are solid glass, so installing wireless wall-mounted controls was the perfect solution to allow the buildings to maximize use of available daylight at all times,” said Wakefield.
The recently rebuilt building will be NASA’s first carbon neutral facility, which means it will produce enough energy on site from renewable sources to offset what it requires to operate. The facility will also reach for the U.S. Green Building Council’s Leadership in Environmental and Energy Design (LEED) Platinum status, which is the highest LEED rating.

Lutron’s Radio Powr Savr™ wireless occupancy/vacancy sensor, EcoSystem™ T4 CFL ballast and Radio Powr Savr wireless daylight sensor have been named winners of the “2011 Top Products Awards” by the readers of the trade publication Building Operating Management magazine.
The Top Products Awards recognize the most popular manufacturers and suppliers of the year, as determined by building and facility executives who sought further information about new products that appeared on the FacilitiesNet.com. Awards are given to the products that finished in the top 10 percent of all items posted between October 1, 2009 and September 30, 2010.
Ideal for new construction or retrofit applications, Lutron’s Radio Powr Savr occupancy/vacancy sensors are ceiling-mounted and wall-mounted RF sensors that install in minutes and require no wiring. Proprietary XCT™ Technology allows Lutron Radio Powr Savr sensors to distinguish the difference between actual motion in a space and background interference that would typically cause performance problems for sensors without this technology (i.e. turning lights on or off at the wrong times). Occupancy decisions using XCT Technology are made solely on the basis of actual movement, while background interference and noise are disregarded. This helps to reduce performance problems for sensors equipped with XCT (called “false on” and “false off” events) because of Lutron’s advanced signal processing. Depending on the overall system configuration, Radio Powr Savrs can significantly reduce lighting electricity usage in a given space.
As with all EcoSystem components, the CFL ballast is adaptable, with one model that can control both 26W and 32W T4 lamps. It is energy efficient, with ultra-low (<1W) stand-by power requirements. And it is expandable, appropriate for everything from a single room to an entire building. The CFL ballast can dim lights down to 5%. Customers operate EcoSystem™ through a variety of control options including GRAFIK Eye® QS, Energi Savr Node™ Modules and Quantum™ total light management system.
The Radio Powr Savr wireless daylight sensor is a battery-powered, ceiling-mounted sensor that saves energy by dimming or turning off electric lighting when sufficient daylight is available. The sensor detects light in the space and then wirelessly transmits the appropriate commands to the compatible dimming and switching devices via Lutron Clear Connect™ Radio Frequency (RF) technology. The RF-linked controls then adjust the lights to take advantage of natural daylight. The addition of the wireless daylight sensor to the Radio Powr Savr family of wireless sensors helps to expand savings from a simple occupancy sensing strategy to now include a simple daylight harvesting solution too.
“It is an honor to be recognized by a publication such as Building Operating Management,” said Ed Blair, Vice President & General Manager of Commercial Solutions at Lutron. “Their readership represents market sectors that are important to us. Lutron is committed to developing sustainable and expandable total light management solutions, and the number of requests for information regarding these three products shows that we’re meeting real needs.”

 California new Title 20 standards, which went into effect January 1, 2010, created new energy efficiency standards for 150-500W metal halide light fixtures used in indoor and outdoor applications. These fixtures may not be manufactured in the State of California unless they meet the new standards.
Indoor fixtures: First, no probe-start ballasts are allowed. Next, the fixture must comply with the Energy Independence and Security Act of 2007, which imposes a minimum acceptable efficiency of 88% for its pulse-start ballast.
But then Title 20 goes beyond EISA 2007, requiring one of four options.
1. Minimum ballast efficiency of 90% for 150-250W lamps and 92% for 251-500W lamps. Basically, by choosing a higher-efficiency ballast than that required by EISA 2007, the Title 20 requirement can be satisfied.
2. A ballast with an efficiency of 88% or greater AND an integral occupancy sensor with a default setting to automatically reduce lamp power through dimming by at least 40% within 30 minutes or less of an area being vacated.
 3. A ballast with an efficiency of 88% or greater AND an integral photocontrol to automatically reduce lamp power through dimming by at least 40% in response to daylight contribution to light levels.
4. A ballast with an efficiency of 88% or greater AND a relamping rated wattage (stated on a permanent, pre-printed factory-installed fixture label) with only one of these four bins: a) 150-160W, b) 200-215W, c) 290-335W or d) 336-500W (if the fixture is able to operate 336-500W lamps, it must be prepackaged and sold together with at least one lamp per socket with a minimum lamp mean efficacy of 80 lumens/W.
Basically, the ballast must be even more efficient than EISA 2007 or use lighting controls. The intent appears to be to push end-users towards use of 150-500W electronic ballasts, which currently represent 2% of total HID ballast shipments, according to 2009 NEMA data. Alternately, users can stick with magnetic ballasts that offer a compliant level of efficiency or control capability. Magnetic ballasts would be most desirable for applications where electronic ballasts are not yet available or where the alternative has a form factor requiring modification of the luminaire. In addition, electronic ballasts are still proving themselves in extreme environments in which magnetic HID ballasts have already proven themselves.
Of course, there are exceptions, which negate the minimum ballast efficiency requirements for certain metal halide lighting systems if they meet any of the following conditions:
1. Luminaires that use regulated lag ballasts.
2. Luminaires that use electronic ballasts that operate at 480V.
 3. Luminaires that a) are rated for use only with 150W lamps, b) are rated for use in wet locations [as specified by NEC 2002, Section 410.4(A)], AND c) contain a ballast that is rated to operate at ambient air temperatures above 50C, as specified by UL 1029-2001.
Outdoor fixtures: Same as the above, but outdoor fixtures that may comply with Option #3 must comply with at least one of the other options.
Future requirement: Starting January 1, 2015, indoor 150-500W metal halide fixtures must comply with Option #4 (wattage bin ranges) in addition to at least one of the other compliance options.
