The California Energy Commission (CEC) has published a voluntary quality specification for omnidirectional and directional LED replacement lamps intended to replace screwbase incandescent lamps in light fixtures other than colored lamps, light strips and rope lights, linear pin-based lamps and integrated light fixtures. Research conducted by the California Lighting Technology Center resulted in two conclusions. [...]

The U.S. Department of Energy recently completed Series 19 of testing through the DOE Solid-State Lighting CALiPER program. Report 19 reviews the independently tested performance of nine LED linear pendants and also evaluates a supplemental collection of 11 linear pendant products available in both an LED and fluorescent version. In general, the LED versions were [...]

University of Georgia researchers have fabricated an LED that emits warm white light using a single light emitting material (phosphor) with a single emitting center for illumination. “Right now, white LEDs are mainly used in flashlights and in automotive lamps, but they give off a bluish, cool light that people tend to dislike, especially in [...]

Guest post by Jim Brodrick, U.S. Department of Energy OLEDs don’t get as much publicity as LEDs, because they’re a good five to seven years behind their inorganic cousins in terms of commercial deployment. But they have considerable potential to save energy, as well as a number of other advantages. So where do we stand [...]

The U.S. Department of Energy has released a CALiPER 2012 Year in Review report that summarizes recent testing results and provides an overview of multi-year trends, available here. Since its inception in 2006, the CALiPER program has tested more than 500 products, revealing a variety of performance trends, holding manufacturers accountable for claims, and identifying [...]

Guest post by Jim Brodrick, U.S. Department of Energy Because they’re directional, reflector lamps are an important tool for both ambient and accent lighting, especially in residential and light commercial applications. One common type of reflector lamp is the PAR lamp, which is often used in demanding applications where color quality and visual appearance are [...]

The U.S. Environmental Protection Agency has posted the final ENERGY STAR Luminaires Specification Version 1.2 criteria. You can view the specification at the Light Fixtures web page here.

LEDucation 7 will take place on Wednesday, March 20, 2013 in New York City with an expansion in exhibit space and educational sessions at the Hotel Pennsylvania – Penn Plaza Pavilion. Over [...]

The U.S. Department of Energy has completed Series 20 of testing through the DOE Solid-State Lighting CALiPER program, available here. Report 20 evaluates the independently tested photometric performance of 38 LED PAR38 lamps, with results showing significant improvement versus earlier CALiPER testing of similar products. All of the LED PAR38 lamps tested offer substantial energy [...]
