NEMA’s index for LED A-line replacement lamps increased for the second consecutive quarter in Q3 2013. Shipments during the quarter registered a gain of 71.9 percent compared to the previous quarter. Shipments rose 60.2 percent on a year-over-year basis. Halogen A-line lamp shipments improved as well, eclipsing the level during the same period last year [...]

Cree recently demonstrated an LED concept luminaire operating at 200 lumens/W, which is more than twice the efficiency of the best linear fluorescent luminaires. The prototype leverages Cree’s vertical integration with innovations in LED chips, optics, materials technology and novel system design to deliver unprecedented performance. The 3,200-lumen concept luminaire delivered greater than 200 lumens/W [...]

Hubbell Lighting recently launched three new LED luminaires from Columbia Lighting—the LWC Premium Wraparound, LPT Premium Lensed Striplight and LRO Lensed Striplight, well suited for lighting kitchen or dining areas, work or utility spaces, hallways, restrooms, and other areas with lower ceilings. Columbia Lighting’s LWC Premium Wraparound fixture is available in lumen packages ranging from [...]

My January column for the Lighting Controls Association blog and newsletter lightingCONTROL summarizes the major lighting changes in the new LEED v4. Of particular interest for general lighting is a new “lighting quality” provision (EQc6, Interior Lighting, 1 point), which lists eight options and requires adoption of at least four of them in the design. [...]

NEMA’s Electroindustry Business Conditions Index (EBCI) for current conditions in North America slipped below the 50-point level typically associated with expansion in January for the first time since October 2012. The index declined for the third straight month, falling to 40.6 from 52.8 in December. On the plus side, confidence in future business conditions again [...]

Eaton’s Cooper Lighting division is sponsoring the Outdoor Lighting Design Award for the 2014 Illuminating Engineering Society’s (IES) Illumination Awards program. The Outdoor Lighting Design Award recognizes excellence in lighting design and application in all aspects of exterior lighting. The Outdoor Lighting Design Award celebrates achievements in aesthetics, applied technical acumen, creative solutions to demanding [...]

NEMA’s shipment indexes for T5, T8 and T12 lamps retreated during 2013Q3, decreasing by 7.3%, 9.4% and 5.5%, respectively. Year-over-year (y/y) performance showed mixed results for the different lamp types. The T5 lamp index increased by 5.7% compared to 2012Q2. T8 lamp shipments improved as well increasing by 10.7%. Shipments of T12 lamps continued to [...]

GE’s new Lumination IS Series LED Luminaires are designed to deliver high light output coupled with energy efficiency in a sleek, streamlined form factor for low bay, open ceiling environments. The luminaire’s indirect light source produces an even glow that radiates from its aerodynamic “reflector” design, yielding greater illuminance over vertical and horizontal surfaces with [...]

My contribution to the December 2013 issue of ELECTRICAL CONTRACTOR describes four interesting lighting technologies that offer a new potential for lighting. Field-induced polymer electroluminescent, quantum-dot LED, visible light spectrum communication, and bioluminescent illumination. Check it out here.
