LRC Releases New Report on LED Horticultural Lighting Systems

The Lighting Research Center (LRC) at Rensselaer Polytechnic Institute has published a new report on the energy and economic performance of LED horticultural luminaires. The LRC evaluated key factors such as power demand, life-cycle cost, luminaire intensity distribution, and luminaire shading. Of particular importance is the fact that the LRC considered the effectiveness of the entire lighting system for a controlled growing environment.

The Effectiveness of Apple’s iPad Night Shift Application Tested by Lighting Research Center

The light emitted by portable electronic devices (PEDs), particularly when used at night, has drawn a great deal of interest among sleep researchers, healthcare professionals, and the media. Research shows that exposure to light at night (LAN) may be associated with poor sleep and may lead to diminished alertness and performance throughout the day. Exposure to LAN can also acutely suppress melatonin, a hormone produced at night and in darkness, which tells the body it is nighttime. The short-wavelength “blue” light emitted by electronics can be especially disruptive to melatonin production, and the proximity to the eye when PEDs are in use only aggravates the threat to getting a good night’s sleep.

Rethinking Exposure to Saturated Colored Light

Two key physical properties of light participate in color vision: wavelength and power. They factor into a light source’s spectral power distribution, which describes the amount of light power at each wavelength in the visible spectrum (which ranges from approximately 380 nanometers to 780 nanometers) that is emitted by that particular source. Power is a measure of the amount of light from each wavelength that arrives at a defined location per unit time.

Lighting Research Center Issues New Report: LED Lighting in a Campus Building

The Lighting Research Center (LRC) at Rensselaer Polytechnic Institute recently evaluated a newly constructed building at Siena College—Rosetti Hall, a 25,000 square foot, 3-story, contemporary brick building that includes classrooms, meeting rooms, and offices. The New York State Energy Research and Development Authority (NYSERDA) awarded funding to change the lighting specification from the originally specified conventional fluorescent lighting to all light emitting diodes (LEDs), designed by Engineered Solutions of Clifton Park, N.Y., and to have the project evaluated as a DELTA demonstration project by LRC. The 20-page full color, illustrated report, “LED Lighting in a Campus Building” detailing the project evaluation and findings, is available for free download from the LRC website.
