LEDs on Retrofit Fast Track for Historically Styled Lighting Applications

LEDs on Retrofit Fast Track for Historically Styled Lighting Applications

By Tom Salpietra, President & COO, EYE Lighting International Since street lighting became popular in the U.S. in the last half of the 1800s, the light source has migrated from natural gas to mercury, then to sodium lamps, and now to LEDs. While the ordinary “cobra head” and shoebox are the most common luminaire designs found on top of light poles today, over the years many cities invested in historically styled lighting fixtures for their downtown shopping and residential streets Read more [...]
Past as Prologue: What’s Ahead for Solid-State Lighting?

Past as Prologue: What’s Ahead for Solid-State Lighting?

By James Brodrick, U.S. Department of Energy Over the last decade, solid-state lighting (SSL) has evolved from a novelty to a viable option for most general lighting applications. Back in 2005 some likened the lighting market to the Wild West—not only because early SSL products didn’t match the performance of the technologies they were intended to replace but also because a lack of standards caused a great deal of confusion that was compounded by exaggerated performance claims. Today Read more [...]
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 [...]
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 [...]
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 [...]
Luminaire Intelligence

Luminaire Intelligence

New lighting technologies such as LED and fluorescent light sources, lighting controls, and daylighting create excellent opportunities for energy savings.  As the market shifts toward greater energy efficiency and intelligence in systems, luminaires (a.k.a. light fixtures) are the first thing to consider when planning your lighting strategy. In the lighting world, luminaires are the complete package.  Luminaires are electrical devices that integrate everything from the power supply 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 [...]
