Light Bulb Amendment puts U.S. Jobs at Risk

Light Bulb Amendment puts U.S. Jobs at Risk

Yesterday NEMA sent the below letter to every member in the U.S. House of Representatives.   Support US Jobs and Oppose Burgess Amendment on Light Bulbs Dr. Burgess (R-TX) has announced he will be offering an amendment that has the impact of threatening U.S. manufacturing jobs.  The National Electrical          Manufacturers Association (NEMA) strongly opposes the Burgess amendment and urges you to vote against it.  The amendment Read more [...]
Standards Harmonization Good for Growth of Solid State Lighting

Standards Harmonization Good for Growth of Solid State Lighting

Recently, NEMA published SSL 4-2012, SSL Retrofit Lamps: Suggested Minimum Performance Requirements.  The purpose of this standard is to provide suggested minimum performance levels for SSL retrofit products. Federal programs such as Energy Star set high performance goals to encourage growth of such products, but do not provide minimum acceptance criteria for products as a whole.  Since its publication, NEMA has been approached by several organizations wishing to adopt, in part or in total, Read more [...]
Shedding Some Light on Consortium Collaboration

Shedding Some Light on Consortium Collaboration

In October 1879, Thomas Edison perfected a workable electric light at his laboratory in Menlo Park, N.J.  Thus, the incandescent lamp was born.  More than 80 years later, the first practical visible-spectrum (red) light emitting diode (LED) was developed by Nick Holonyak at General Electric Company.  Almost 50 years later, the lighting industry has evolved and added a variety of products to support and improve upon Mr. Edison’s incandescent lamp. Today, NEMA’s Lighting Read more [...]
US Participation Needed in Quantum Dot Standards

US Participation Needed in Quantum Dot Standards

The TC 113 TAG is about to introduce new work proposals for a specification for characterizing luminescent nanoparticles (e.g. Quantum Dots), and a template specification sheet for these nanoscale materials.  QD’s as a game changer in next-generation LED lighting and medical imaging technologies have begun making inroads in the marketplace, so standardized characterization techniques and a template specification are critical to encourage common language communication between nanomaterial Read more [...]
Performance Makes a Comeback with New Light Bulb Labeling System

Performance Makes a Comeback with New Light Bulb Labeling System

Ever thought about what you should consider when buying a light bulb?  Any clue what a lumen is? Chances are if you’re heading out to your local supermarket or hardware store to pick up some light bulbs, you’ll find a store attendant and ask what aisle the 100W (or 75W, 60W, etc.) light bulbs are in and pick up a package. Now, say you head to the car dealership looking to purchase a new ride.  You’ll walk around the lot as a salesperson shows you vehicle after Read more [...]
NEMA Lighting Division efforts bear fruit in California

NEMA Lighting Division efforts bear fruit in California

This week the State of California Public Utilities Commission (CPUC) approved and published their Strategic Lighting Plan, which was two years in the making. NEMA staff and members participated directly in the development and drafting of the SLP from start to finish to provide the manufacturer perspective in effort to balance out the advocates and regulators, and to serve as a reality check by leveraging NEMA's extensive experience with consumer acceptance and consumer desires.  The Strategic Read more [...]
Toyota Should Take a Lesson from Burner Controls Industry

Toyota Should Take a Lesson from Burner Controls Industry

The sudden acceleration of Toyota vehicles may be due to software issues; if this is the case then there are valuable lessons for all standards developers.  So many products now incorporate electronic controls, yet many have not been evaluated to determine what happens when a failure occurs.  For mechanical systems we have tried and tested methods to handle failure - a vehicle's hydraulic brake system has a cable emergency brake back-up. The aerospace industry builds in triple redundancy Read more [...]
Lighting industry position on light at night and biological factors forthcoming

Lighting industry position on light at night and biological factors forthcoming

The NEMA Lighting Systems Division is concerned over numerous recent efforts to raise awareness of light at night and potentially related effects on biological processes.  While many of these are well-intended, they often fall short of being credible, and could do more harm than good.  There are many instances where lighting at night is favored and desired for safety and aesthetics, and ultimately NEMA lighting manufacturers wouldn't sell products if they weren't in demand.  Read more [...]
NEMA Addresses SSL Dimming Challenges

NEMA Addresses SSL Dimming Challenges

The NEMA Lighting Controls and Solid State Lighting Sections have co-produced a white paper on the subject of dimming screw-base integrated ballast LED lamps. It is designated LSD-49 and is titled "Solid State Lighting for Incandescent Replacement—Best Practices for Dimming". NEMA and the SSL industry hope that by issuing guidance as early as possible on this subject, SSL technology can avoid the pitfalls associated with less than compatible self-ballasted CFL and Dimmer combinations.
