Guest post by Jim Brodrick, Department of Energy Solid-state lighting has been developing so rapidly over the past few years that it sometimes seems the only constant is its forward progress. The number of applications for which LED lighting products can compete with their traditional counterparts is growing all the time, and performance has continued [...]
The U.S. Green Building Council (USGBC) recently announced that the Green Building Certification Institute (GBCI) has certified the 10,000th LEED commercial project. Created in 2000, the LEED green building program has become a global symbol of sustainable building certifying more than 1.4 million square feet of new and existing buildings every day. The Live Oak [...]
The DSBL Bi-Level Stairwell luminaire by Deco Lighting—designed for minimal occupancy applications such as stairwells, corridors, restrooms, laundry rooms and dorms—incorporates an integral occupancy sensor that automatically reduces light output to save energy during unoccupied times.
The ninth annual Lighting for Tomorrow competition recognizes the best designed, energy efficient lighting products in the residential market. For the second year the competition has expanded its scope to include solid-state lighting (SSL) replacement lamps and lighting controls. Lighting for Tomorrow continues to challenge manufacturers to improve their design of SSL fixtures and to [...]
A fascinating study conducted by the Lighting Research Center (LRC) at Rensselaer Polytechnic Institute found that satellite images of outdoor lighting are unrelated to actual light levels reaching the eye. These results challenge previous studies linking satellite images of outdoor lighting with increased incidences of breast cancer. Light entering the eye regulates our body’s circadian [...]
Offered in a 3-in. round beveled or square beveled trim, Edge Lighting’s Sun 3 provides a precise 23-degree beam of warm white light from a recessed, in-grade LED luminaire. A remote 12VAC power supply powers the luminaire and an internal LED driver controls the high-intensity LED. An optional optical assembly may be added to tilt [...]
Dimming offers greater flexibility for lighting systems, providing users with more control over their lighting conditions to support visual needs and enabling energy management strategies that can reduce energy costs. Traditionally limited to high-end commercial building applications, such as conference rooms and private offices, dimming is now being implemented throughout buildings. In its August issue, [...]
ILEX Architectural Lighting, a manufacturer of lighting solutions for the hospitality and commercial markets, recently announced the official launch of its newly redesigned website. ILEX modified the design and functionality on ILEXLight.com to enhance the user experience and engage the visitor with a full offering of product details, specifications and recommended companion products / offerings.
