DoE Reports Round 4 of CALiPER Testing Program Results: Inaccuracy of Performance Data
DoE Reports Round 4 of CALiPER Testing Program Results: Inaccuracy of Performance Data In round 4 of CALiPER testing DoE had a closer look on MR16 and T8 replacement products as well as on two downlights, seven task lamps and five "outdoor & other" fixtures. The DOE Commercially Available LED Product Evaluation and Reporting (CALiPER) Program, formerly called the Commercial Product Testing Program, supports testing of a wide, representative array of SSL products available for general illumination. The Department allows its test results to be distributed in the public interest for noncommercial, educational purposes only. Read more »

U.S. Department of Energy publishes final report on SSL efficacy for todays products
U.S. Department of Energy publishes final report on SSL efficacy for todays products DoE SSL luminaries test shows a huge discrepancy between manufacturer claims and actual tested luminaire performance. Numerous products for differnt applications were tested in three rounds. To give consideration to real-life conditions off state power consumption (standby power) was taken into account. Pilot test results were published in December 2006, first round results followed in March 2007. Now Final results are published for free distribution in the public interest for noncommercial, educational purposes. Read more »

UCI Researchers Find LED Products Billed as Eco-Friendly Contain Toxic Metals
LED products usually are electronic products that should be handled as electronics scrap if disposed, anyway. A realease of potentially hazardous substances under regular use is very unlikely, even when broken. LED professional does not agree with the generalized conclusions of this research. However, it is important to challange statements of PR and lobbies to boost more eco-friendly products. In fact, light-emitting diodes of tested holiday bulbs, traffic lights and car beams marketed as safe, environmentally preferable alternatives to traditional lightbulbs actually contain lead, arsenic and a dozen other potentially hazardous substances, according to newly published research.

Studies Published on Flicker Perception from SSL Systems - ASSIST to Release Related Recommendation
Studies Published on Flicker Perception from SSL Systems - ASSIST to Release Related Recommendation Flicker and stroboscopic effects have been a concern with solid-state lighting (SSL), and industry and the ENERGY STAR program have debated recently the effects of frequency and other driving modes on the perception and acceptability of flicker. To provide further data and guidance in this area, the Lighting Research Center (LRC) at Rensselaer Polytechnic Institute has conducted human factors studies of flicker that were recently published in the Lighting Research and Technology journal. The studies, funded by the Alliance for Solid-State Illumination Systems and Technologies (ASSIST), will become the basis for future ASSIST recommends guidelines on flicker from SSL systems.

DOE Publishes Updated Recommendations for Testing and Reporting LED Luminaire Lifetime
The U.S. Department of Energy (DOE) has published an updated version of the guide LED Luminaire Lifetime: Recommendations for Testing and Reporting, the latest edition in a series of publications on LED product performance and lifetime. The guide was developed by a working group under the auspices of DOE and the Next Generation Lighting Industry Alliance, composed of a diverse group of experts in reliability, lighting, and LED technology. Their recommendations are an important step toward consistent, industry-wide understanding of LED luminaire lifetime, and will assist standards organizations in their work. Read more »

Independent Research using Xicato Spot Modules: Link Between Light Quality and the Attraction of Retail Displays
Independent Research using Xicato Spot Modules: Link Between Light Quality and the Attraction of Retail Displays There is a strong link between the quality of accent light sources, in terms of color rendering ability and in particular the rendering of deep reds, and the attention-grabbing potential of retail displays, according to the outcome of an on-site evaluation by end-users and lighting designers conducted by independent researcher, Colette Knight and peer reviewed by University College London. Shoppers and lighting designers took part in the experiment carried out in a House of Fraser store in London. It showed that there was no statistical difference between the appreciation of colors rendered with halogen or Ra 95 (R9 >95) LED sources, whereas the rating was lower for Ra 80 (R9<20) LED sources. This translated directly into the rating of the display itself in terms of its attraction. Read more »
