Researchers at the Natick Soldier Research, Development and Engineering Center are investigating the effects of different types of lighting in military shelters on Soldiers. Specifically, members of NSRDEC’s Cognitive Science Team are examining the effect of lighting on mood, or affective state, as well as visual acuity, cognitive alertness/awareness and the ability to perform tasks. [...]

The California Lighting Technology Center recently tested 26 LED A-lamp products marketed as alternatives to 60W incandescent A-lamps. Data collected on power (W), voltage (V), luminous output (lumens), correlated color temperature (CCT), color rendering index (CRI), rated life, and dimming performance allowed for comparison with manufacturers’ claims as well as current lamp quality standards. The [...]

The rapid development of lighting technologies, particularly solid-state systems using LEDs, has opened a universe of new possibilities as well as new questions about roadway lighting in the United States, which for decades has been dominated by the use of HPS lamps. Other light source technologies have also been angling for roadway market share. There [...]

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 [...]

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 [...]

A new market research report published by Lighting Solution Development reveals a large and rapidly expanding market for horticultural grow lights to legal, commercial marijuana growers. As of October, 2013, 20 states plus the District of Columbia have varying degrees of decriminalization for marijuana, including legal commercial growing. Two states, Colorado and Washington, have legalized [...]

The CSIL Centre for industrial Studies in Milano, Italy recently published a new report, E-Commerce in the Lighting Fixtures Sector. The report states that e-commerce accounts for 4% of the $75 billion global luminaire market, including both B2B and B2C. North America is the largest e-commerce market for luminaires; its incidence on the world market [...]

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: [...]
