The Illuminating Engineering Society (IES) recently published Recommended Practice for Daylighting Buildings (RP-5-13). This Recommended Practice module includes the most up-to-date data on the many benefits of daylighting, including energy savings of 40-50% or more. It also offers information and expertise on daylight delivery methods, glazing systems, shading techniques, control strategies and daylight performance simulation [...]

NEMA’s indexes for HID lamp shipments continued to hover near historical low levels during 2013Q2. The index for mercury vapor lamp shipments continued to track downward, declining by 8.2% on a year-over-year (y/y) basis. Likewise, shipments of metal halide lamps fell 6.4% y/y, landing at the second lowest level in the series history. Sodium vapor [...]

The National Lighting Product Information Program (NLPIP) at Rensselaer Polytechnic Institute’s Lighting Research Center (LRC) recently released its latest publication, Lighting Answers: Plasma Lighting Systems. Plasma lighting systems, also known as electrodeless high-intensity discharge, light-emitting plasma, high-efficiency plasma, or advanced plasma lighting, are emerging in the marketplace primarily for high-bay and outdoor lighting applications. Many [...]

Designed as an LED retrofit solution for linear fluorescent luminaires, Cree’s UR Series LED Upgrade Kit operates at 102 lumens/W. Available in 2- and 4-ft. lengths and various lamp configurations, the UR Series features simple installation in virtually any linear fluorescent luminaire due to a unique magnet design, quick connect and form-fitted driver. For a [...]

After a hiatus of several months, NEMA’s Electroindustry Business Conditions Index (EBCI) for current conditions in North America is back. The EBCI measured 56.3 in October, down slightly from 56.7 in June, the last time the index was released, but still showing signs of improvement in the business environment. Respondents remained optimistic on balance regarding [...]

The Energy Center of Wisconsin offers a wide range of online education courses, including a number of lighting courses, with topics ranging from daylighting to specifying LED products. Check out the course listing here. Note some courses present a cost for either viewing or getting education credit.

Showing a steady increase in the demand for design services, the Architecture Billings Index (ABI) continues to accelerate, as it reached its second highest level of the year. As a leading economic indicator of construction activity, the ABI reflects the approximate nine to twelve month lead time between architecture billings and construction spending. The American [...]

The U.S. Department of Energy (DOE) has published a new report, Color Maintenance of LEDs in Laboratory and Field Applications. Although concern for parametric failure of LED lighting products has largely been focused on lumen maintenance, color shift is a cause of early failure for some products, especially in applications where visual appearance is critical. [...]

Uniquely designed with LEDs in the front and the rear of the bulb, the TerraLUX Decorative MR16 LED Lamp produces warm light in all directions that is ideal for use in high-end decorative luminaires. The 4W lamp replaces 20W halogen MR16s and is available with a 20-degree narrow flood beam, 3000K color temperature and 90+ [...]
