Researchers at the Universities of Basel and Valencia recently reported that they have succeeded in laying the ground work for a novel solid-state light source based on light-emitting electrochemical cells (LECs). The group, led by Basel professors Catherine E. Housecroft and Edwin C. Constable, see LECs as potentially advantageous compared to LED because they are [...]

2014 Nobel Prize in Physics winner Professor Amano Hiroshi, recently stated LED lamps will be a mainstream consumer light source by 2016, but challenges remain. Primarily, he points out, costs must come down further, starting with production costs, which should come down five times by 2020. For this to occur, demand must increase globally and [...]

The North Carolina Clean Energy Technology Center has relaunched the Database of State Incentives for Renewables and Efficiency (DSIRE). Funded by the Department of Energy, DSIRE offers a comprehensive source of information related to policies and incentives that support the nation’s use of renewable energy and energy efficiency technologies. The new and improved website offers [...]

Cooledge Lighting has expanded its “light sheet” portfolio with SQUARE, a 1×1 lighting product that requires no heat-sink and can be snapped together to create a larger luminous plane capable of being trimmed to size, even while powered. The light source can be affixed to almost any surface (and is flexible, allowing wrapping around columns [...]

The relationship between lighting and productivity has been the subject of study for almost 100 years, but determining a definitive, quantifiable relationship remains elusive. That was the consensus of a three-person Light and Productivity panel of experts assembled by the National Lighting Bureau as part of its annual forum conducted in conjunction with the EdisonReport. [...]

The Illuminating Engineering Society is seeking experts to present at the 2015 Annual Conference being held in Indianapolis, Indiana this November 8-10. (This is a call for presentations, not to be confused with the Call for Papers.) The deadline is March 20, 2015. Click here to learn more and submit a proposal. LightShow West, to [...]

To celebrate the UN-designated Year of Light, the Illuminating Engineering Society is holding a photo contest. From IES: Every month we will announce a “Theme of the Month” to which you will post “lighting” photos related to the chosen theme. You can post as many photos as you wish and at the end of each [...]

A newly revised standard from ASHRAE and IES seeks to provide greater guidance and a more comprehensive approach to retrofit of existing buildings for increased energy efficiency. ANSI/ASHRAE/IES Standard 100-2015, Energy Efficiency in Existing Buildings, provides comprehensive and detailed descriptions of the processes and procedures for the retrofit of existing residential and commercial buildings in [...]

The U.S. Department of Energy’s CALiPER program has released Report 20.3, which is part of a series of investigations on LED PAR38 lamps. Report 20.3 focuses on an evaluation of robustness. Three samples each of 40 of the Series 20 PAR38 lamps (including LED and benchmark conventional lamps) underwent multistress testing, whereby samples were subjected [...]
