Guest post by Jim Brodrick, U.S. Department of Energy t’s been a while since I’ve written about DOE’s CALiPER testing program, and the Round 11 Summary Report was published this week. As always, the results are worth noting. For those of you who don’t know, CALiPER tests a wide range of solid-state lighting products that [...]

The U.S. Department of Energy has completed Round 11 of product testing through the its CALiPER SSL program. Round 11 included five primary focus areas: * roadway arm-mount luminaires * roadway post-top luminaires * linear replacement lamps * high-bay luminaires * small replacement lamps (MR16, PAR lamps, A-lamps, and a candelabra lamp) As a benchmark, [...]

Room surface finishes can play a significant role in maximizing the efficiency of a lighting system because lighter finishes can produce relatively higher light levels and perceptions of brightness. In fact, in an existing space with a large area of dark surfaces can improve light levels and visual comfort almost immediately by simply repainting those [...]

Focal Point has expanded its Verve family with Verve IV, combining a classic curved shape with high-performance optics and new shielding options. The luminaire may be specified with a radial or flat baffle or parabolic louver to deliver 40% downlight standard, then add optional reflectors to increase downlight to 100%.

Redwood Systems, a developer of network-based power and control lighting systems, recently announced it has received a $1 million grant from the U.S. Department of Energy’s Small Business Innovation Research (SBIR) program. The program was established to help drive innovation and growth through the engine of small business. Last year, Redwood was awarded Phase I [...]

Guest post by Jim Brodrick, U.S. Department of Energy Some of you may have seen a new report on street lighting by the Lighting Research Center (LRC) at Rensselaer Polytechnic Institute. A number of people have asked for my comments on that report, so here goes. In a nutshell, the LRC report implies that GATEWAY [...]

The National Lighting Product Information Program (NLPIP), based at the Lighting Research Center in Troy, NY, recently released its latest Specifier Report, designed to provide objective performance information on existing street lighting technologies includingLED, induction, and high pressure sodium streetlights. NLPIP performed photomet­ric evaluations of 14 streetlights that used either HPS, pulse-start metal halide (PSMH) [...]

I authored an article for the June issue of TED Magazine that covers developments in the growing >150W HID electronic ballast segment. Check it out here.

A space’s lighting defines its personality and how people perceive it, which in turn affects how they feel about being there. Below are various lighting effects that can take the same space and transform it into different environments. Psychological impact Lighting effect Light distribution TENSE Intense direct light from above Non-uniform RELAXED Lower overhead lighting [...]
