Charge of the Light Brigade
Helping the 100-plus-year-old GE Lighting bridge the gap between Edison’s incandescent and SSL is a man who is equal parts old world and new (think Teddy Roosevelt meets Steve Jobs). Last June, GE promoted Jaime Irick to president and CEO of GE Lighting Solutions. In that role, he partners with GE Lighting president and CEO Maryrose Sylvester to drive the development, growth and management of GE’s LED product business for both the consumer and professional markets. » More
LRC Study Challenges Claims that Satellite Images of Outdoor Lighting Predict Breast Cancer
A recent study conducted by the Lighting Research Center (LRC) at Rensselaer Polytechnic Institute found that satellite images of outdoor lighting are unrelated to actual light levels reaching the eye. These results challenge previous studies linking satellite images of outdoor lighting with increased incidences of breast cancer. Light entering the eye regulates our body’s circadian rhythms, and disruptions in these rhythms may lead to serious health problems such as cancer. However, according to the LRC study, the spectrum, quantity and duration of light exposure reaching the eye must be specified in order to determine the effects of light on human health, and satellite photometry cannot do this. » More
DOE to Host Webcast on High-Efficiency Troffer Specification
On October 25, 2011, the U.S. Department of Energy (DOE) will host a 90-minute live webcast on the high-efficiency troffer specification developed by a cross-cutting project team from DOE's Commercial Building Energy Alliances (CBEA). » More

The Case for Performance Specs

Municipalities undertaking street lighting projects should adopt RFPs with a performance specification rather than the more common “three-name spec,” says Paul Mitchell, regional manager—sales and education with Sternberg Lighting.

The three-name spec is sometimes mandated due to the state or federal monies tied to the project. In other cases, a city may be concerned that a one-name spec or sole-source listing will lead to them paying more than they should. Another goal to create equal ground or fair market competition among vendors.

However, Mitchell says this approach is not right for LED luminaires in particular. “Municipal specifiers often end up not getting the product(s) they wanted,” he says. “One reason for this is that it is very difficult to identify three LED luminaires that are truly equal, particularly when it comes to decorative street lighting.” » More

Who will be the dominant player in the LED luminaire market five years from now?
Traditional luminaire manufacturers
Electronics companies

Last month’s survey question:
In five years, which source will be more prevalent in residential applications?

LEDs = 69% CFLs = 31%

Retrofit Kits for Fluorescent Lamps
Cooper Lighting introduces a series of four contractor-friendly Metalux fluorescent retrofit kits designed to meet and exceed today’s energy needs and guidelines while improving light quality. The Metalux Commercial, OpticaHP, Archos and Cruze retrofit kits consists of architecturally inspired designs that update a building’s look and value, while offering a wide range of features and benefits that save energy, time and money when compared to similar new construction T8 or T5 luminaire offerings. » More
Occupany Sensors in Wall- and Ceiling-Mount Configurations
Encelium Technologies introduces a new family of low-voltage occupancy sensors. This product line includes a full range of passive infrared (PIR) and dual technology (ultrasonic/PIR) low-voltage sensors available in both wall-mount and ceiling-mount configurations. The occupancy sensors are ideal for use with Encelium’s Energy Control System and also as stand-alone sensor applications for projects where ECS may not be suitable. » More
A Portal for LED Lamps
Lighting Internet Technology Enterprises, LLC (LITE) has launched the “LED Lamp Locator”—a web-based tool that will enhance the ease with which professional lighting users can search, evaluate, compare and specify the market’s broad range of LED replacement lamps. Providing lighting distributors, specifiers, contractors, end users, manufacturers and other lighting professionals with a comprehensive database of current LED lamp products offered by the market’s range of global manufacturers, the LED Lamp Locator will help minimize the confusion and misinformation often associated with the identification and selection of LED lamps in today’s fast-paced and rapidly expanding marketplace. » More
Outdoor Luminaires for Transit Environments
Schréder Lighting US introduces Piano, a family of outdoor architectural luminaires. Performance highlights include:
• ThermiX thermal management for optimum lighting performance
• Electronic power supply is over 90 percent efficient, with surge protection

LED Floodlight for Commercial Applications
RAB Lighting has expanded its family of LED floodlights with the addition of a new 18-W “LFLOOD.” The LFLOOD18 produces 73 lumens per watt and is designed to replace the 70-W metal halide floods found on many commercial building exteriors. » More
    Coming Up in LD+A November

Public buildings and institutions are the theme of the November issue of LD+A. Highlights include:

  • A feature story on the Durham Consolidated Courthouse in Canada where designers creatively borrowed watts from certain areas and spent them in others to create an energy-efficient yet aesthetically pleasing facility. This layered approach sheds appropriate illumination on all the players in the judicial process, from the judge to the jury.
  • Coverage of Goodhue Memorial Hall at the Hackley School in New York where a new library with an entirely new lighting plan has risen from the ashes of a devastating fire in 2007.
  • A report from researchers at the California Lighting Technology Center who argue that “secondary” areas in buildings (stairwells, corridors and service rooms) can offer untapped potential for huge energy savings related to lighting.
  • A newsmaker Q+A with one busy IES Member—Charles Cameron, president of the IES New York City Section, who has also launched a new firm in the past year, while managing the lighting program for a local school.
