The U.S. Department of Energy’s CALiPER program has released a Snapshot Report on LED outdoor area lighting. Based on LED Lighting Facts data through the second quarter of 2014, the report focuses on outdoor area/roadway luminaires, parking garage luminaires, canopy luminaires, and outdoor directional luminaires. As of July 1, 2014, area/roadway products alone comprised 23% [...]

MIT Technology Review recently published an article about how Lighting and the Internet are merging, and what that means. I found this excerpt to be of particular interest: “Another look at how lighting systems are changing will emerge this November, when a 14-story regional headquarters for Deloitte, nearing completion in Amsterdam, will be festooned with [...]

Don Peifer posed this question in his recent column for LD+A: Does the hype surrounding LEDs match the reality? Or put another way: Is the battle over and have LEDs already won? Read an excerpt here. LightNOW’s take: LEDs are still only a tiny fraction of the total installed base but represent a large and [...]

The U.S. Department of Energy’s CALiPER program has released a Snapshot Report on indoor LED luminaires, which utilizes the LED Lighting Facts® program’s extensive product database to help industry stakeholders understand the current state and trajectory of the market for that class of products. Based on data through the first quarter of 2014, the report [...]

Here’s an interesting application for LEDs: growing food on other planets. Researchers at the University of Guelph’s Controlled Environment Systems Research Facility (CERF) are studying LEDs as a light source that can facilitate plant growth in environments where nutrients and electricity are scarce, such as space and even during colonization efforts of other planets. The [...]

The Lighting Research Center (LRC) at Rensselaer Polytechnic Institute recently evaluated a newly constructed building at Siena College—Rosetti Hall, a 25,000 square foot, 3-story, contemporary brick building that includes classrooms, meeting rooms, and offices. The New York State Energy Research and Development Authority (NYSERDA) awarded funding to change the lighting specification from the originally specified [...]

The U.S. Department of Energy has released a report on a GATEWAY demonstration of LED lighting at the University of Florida’s Nadine McGuire Theatre and Dance Pavilion in Gainesville. Four interior spaces—the acting studio, dance studio, scene shop, and dressing room—were fitted with LED luminaires or retrofit lamps along with dimming controls. In addition, the [...]

Republication of Postings from the U.S. Department of Energy (DOE) Solid-State Lighting Program by Jim Brodrick, U.S. Department of Energy [At] LIGHTFAIR International, we saw a lot of T-LEDs (LED T8 replacement lamps), and it’s clear that manufacturers are putting a great deal of thought into how to make those products better, brighter, and easier [...]

This new IES document provides a method for measuring light output and color maintenance of LED lamps, light engines and luminaires. Check it out here.
