Architectural Area Lighting’s (AAL) popular Pivot linear flood light is now available in LED. The Pivot is a flexible lighting solution for both indoor and outdoor applications, serving indirect lighting, perimeter highlighting, wall grazing, sign lighting and wall washing applications. Available in three lengths (2’, 4’, and 8’), each with two lumen packages, the Pivot [...]

In 2009, DOE issued energy standards for commercial general-service fluorescent lamps that took effect July 14, 2012 and eliminated a majority of 4-ft. linear and 2-ft. U-shaped T12 lamps and many 8-ft. T12 and T12HO lamps from the market. Exceptions include lamps with a CRI rating of 87 or higher, lamps designed to operate in [...]

IES has extended its call for papers for its 2014 Annual Conference (Pittsburgh, PA, November 2-4) from June 5 to June 16, 2014. Click here to submit our proposal.

Artist Andela Andrea uses light and materials to create luminous objects and environments that appear surreal, sometimes even alien. Click here to see more.

In December 2013, Precision Paragon conducted its 4th annual state of the lighting industry survey. This year’s survey was distributed to over 5,000 energy-efficient lighting industry professionals. My biggest takeaways were this: The large majority of respondents believe the relighting market is growing. LED luminaires continue to rapidly grow in popularity. Respondents indicate for the [...]

A research team led by the Institut de Physique et de Chimie des Matériaux de Strasbourg (IPCMS, CNRS/Université de Strasbourg), in collaboration with UPMC and CEA, has developed the first ever single-molecule LED. The device is formed from a single polythiophene wire placed between the tip of a scanning tunneling microscope and a gold surface. [...]

Many companies add whiteners to laundry detergent, paints, fabrics and other materials to make whites look “whiter than white,” but the choice of light sources may be even more important, according to new research. Kevin W. Houser, professor of architectural engineering at Penn State University, recently led a study about how well various light sources [...]

Excessive heat generation is one of the main reasons why light-emitting diodes fail. With the Oslon Square, Osram Opto Semiconductors has produced an LED that withstands high ambient temperatures. To ensure that the color point of each LED in a luminaire remains uniform even at higher temperatures, they are measured and binned at 85°C. This [...]

Spanish light artist Roseline de Thélin creates visually stunning holographic light sculptures and installations. Her projects focus on holographic ethereal beings she calls “Homos Luminosos” (luminous beings) as well as organic forms, all using points of light distributed along optical fibers. She uses the relationship between light and dark to create three-dimensional images that are [...]
