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 [...]
NEMA Podcasts Explain New Lightbulb Labels and Lumens

NEMA Podcasts Explain New Lightbulb Labels and Lumens

      To more fully explain America’s transition to energy efficient lighting, NEMA is producing a six-part podcast series focused on the 5LS of Lighting: Location, Lumens, Lightbulbs, Label, and Law.  As utilities, contractors, and consumers attempt to both understand and explain the new lighting world, they can quickly learn the basics.  The most recent releases are included below. Labels Podcast–New lightbulb packaging labels are starting Read more [...]
Reflection on Lightfair

Reflection on Lightfair

Last month, the lighting universe came together at Lightfair (or LEDfair, depending on who you ask).  Manufacturers from far and wide were displaying their best and brightest new technologies.  And though the weather was not always the most inviting, the city of Philadelphia most certainly was.  What a great venue. For those of you who missed it, a couple of key trends for the lighting systems of tomorrow seemed to surface as the week progressed. Flexibility.  Wherever Read more [...]
How can I tell which Exit Sign is best?

How can I tell which Exit Sign is best?

When Energy Star closed the exit sign category, specifiers and inspectors no longer had a mark of distinction with which to identify top-tier products.  There were even instances of people seeking out new old stock Energy Star labeled signs and preferring them over newer (better) signs, just because of the brand recognition of Energy Star. In response to concerns over the loss of the Energy Star program and associated marks, the NEMA Emergency Lighting Section established the NEMA Premium Exit 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 [...]
Seeing the Light Ahead

Seeing the Light Ahead

Greetings from San Diego, California, the (not frozen) site of the U.S. Department of Energy's workshop on R&D in Solid State Lighting. Following a morning meeting today of the NEMA-housed Next Generation Lighting Industry Alliance (NGLIA), three NEMA and NGLIA member companies lead off the 3-day DOE event by challenging participants to "think outside the bulb". Leading off, Greg Merritt of Cree, Inc., challenged a packed house of over 400 participants to debate whether DOE's Read more [...]
The Federal Govt has banned incandescent lamps – FALSE!

The Federal Govt has banned incandescent lamps – FALSE!

Like a weed that keeps reappearing in your garden, the myth that the Federal Government has BANNED the incandescent light bulb continues to crop up and cause angst among consumers.  And what’s worse, pundits and elected officials who should know better are doing their best to help it spread.  It is particularly distressing to hear free-market conservatives spin this issue as another example of government intrusion into our lives and homes. As NEMA, its member companies, Read more [...]
EISA Sets Standards for Lighting the Future

EISA Sets Standards for Lighting the Future

Since the invention of electric light, the incandescent lamp has been the standard.  Why?  They are cheap to produce, can be made in a wide range of sizes, and require no external regulating equipment.  The trouble is that incandescent lamps are based on a design that was developed over a century ago and the majority of their electrical energy consumption produces heat, not light.  If we wanted them to heat our house, this would be a good thing.  For a light source Read more [...]
