IES LD+A Research Matters: G24 Lamps - A New Niche for LEDs


Today’s LED lighting products offer facility owners and managers an opportunity to reduce their lighting system’s power consumption dramatically.  However, the options for updating four-pin (G24) CFL lamps to LED solutions were limited to retrofit kits or new dedicated fixtures until recently.  Over the last few years, manufacturers have improved and developed a cross-section of LED retrofit options including LED replacement lamps that should all be considered when conducting a lighting upgrade.

Researchers Awarded IES Taylor Technical Talent Award for Color Quality Research


Professors Michael Siminovitch and Konstantinos Papamichael of the California Lighting Technology Center, with Dr. Lorne Whitehead of the University of British Columbia and Dr. Jennifer A. Veitch of the National Research Council, Canada have been awarded the 2016 Taylor Technical Talent award from the Illuminating Engineering Society for their research article, “High Color Rendering Can Enable Better Vision without Requiring More Power”.

IES LD+A Research Matters: Next Generation Healthcare Lighting


Three key elements of emerging healthcare lighting design are circadian wellness, dark adaption, and a high-fidelity visual environment for patient care. Solid-state lighting solutions with spectral control capabilities can be seamlessly integrated into healthcare lighting designs using advanced controls and sensor geometry to create a patient-friendly experience. For patients who need to sleep during the day, these technologies can be manually enacted, along with appropriate window shading, to create a nighttime environment at any hour.

OLED Lighting Workshop, May 2016


On May 17, 2016, the OLED Coalition and California Lighting Technology Center collaborated to host the first OLED Lighting Workshop. Leaders in lighting design and manufacturing gathered to mold the future of OLED lighting. Stakeholders in attendance articulated their needs and ideas for maximizing the potential of OLED technology in today’s market.

IES LD+A Research Matters: Short-term Color Preference Comparisons are Inadequate for Optimizing Long-term Illumination


The evaluation of the color rendering performance of electric lighting sources has become a controversial issue, especially in California, where high color fidelity requirements were recently unanimously approved by the California Energy Commission for the next version of energy efficiency requirements for new buildings and major retrofits (Title 24) and light sources (Title 20).  Opponents of the new version of the California energy codes have claimed that the new requirements will result in increased energy consumption and higher cost.  Further, they have claimed that color fidelity metri
