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 [...]
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 [...]

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.
