The U.S. Department of Energy (DOE) has published a new report, Color Maintenance of LEDs in Laboratory and Field Applications. Although concern for parametric failure of LED lighting products has largely been focused on lumen maintenance, color shift is a cause of early failure for some products, especially in applications where visual appearance is critical. [...]

Jim Brodrick on OLED Lighting
Republication of Postings from the U.S. Department of Energy (DOE) Solid-State Lighting Program by Jim Brodrick, U.S. Department of Energy Most of the attention given to solid-state lighting these days focuses on LED products, because OLEDs are several years behind their inorganic cousins in terms of development for general illumination. Despite some encouraging progress (e.g., [...]

Terry Clark on LED Luminaire Flicker
Finelite has released an LED Talks video on the topic of flicker in LED luminaires, which was recently recognized by the IES for inclusion in the 2013 IES Progress Report for “advancement in methods or aids to facilitate lighting design and/or application.” The video is accompanied by a whitepaper. The video, presented by Terry Clark, [...]

LRC ASSIST Guide Helps Multifamily Housing Managers Select LED Lighting
The Alliance for Solid-State Illumination Systems and Technologies (ASSIST), a program of the Lighting Research Center (LRC) at Rensselaer Polytechnic Institute, recently released a new publication to aid owners and facility managers of multifamily affordable and rental housing in selecting LED lighting products. The publication, The Lighting Field Guide: Upgrading to LEDs for Multifamily Housing, [...]
2013 DOE Solid-State Lighting Market Introduction Workshop
The Department of Energy will host its eighth annual two-day SSL Market Introduction Workshop for utility and energy efficiency program managers at the Benson Hotel in Portland, Oregon November 13-14, 2013. A free half-day of pre-workshop sessions will be held on November 12 for those new to or who want a refresher on solid-state lighting. [...]
ELECTRICAL CONTRACTOR Publishes Article on Color Tuning
I recently contributed a feature article to ELECTRICAL CONTRACTOR on color tuning as a capability of LED white light systems. The article talks about the potential utility this capability brings to architectural lighting applications, product developments and research. Check it out here.
DOE Publishes Fact Sheet on LED Product Lifetime and Reliability
Long life has been promoted as a key advantage of LEDs, but understanding and communicating how LED products fail and how long they last is essential. The U.S. Department of Energy has published a new SSL Technology Fact Sheet, Lifetime and Reliability, to help users understand typical causes for LED product failures, the difference between [...]
Jim Brodrick on New DOE Report Estimating LED Savings in Common Lighting Applications
Republication of Postings from the U.S. Department of Energy (DOE) Solid-State Lighting Program by Jim Brodrick, U.S. Department of Energy DOE has released a much-anticipated new report that estimates the savings from using SSL in applications where LEDs compete with traditional sources. Entitled Adoption of Light-Emitting Diodes in Common Lighting Applications, the report not only [...]
DOE Report Estimates LED Savings in Common Lighting Applications
The U.S. Department of Energy (DOE) has released a report analyzing markets where light-emitting diodes (LEDs) compete with traditional lighting sources (e.g., incandescent and fluorescent). The report, Adoption of Light-Emitting Diodes in Common Lighting Applications, provides estimates of current energy savings, plus potential savings if these markets switched to LEDs overnight. Nine markets were analyzed: [...]
