DOE Publishes Technical Brief Clarifying Misconceptions about Safety of LED Lighting

The spectral emission of LEDs is a frequent subject of concern, so to set the record straight, the U.S. Department of Energy has published a technical brief entitled True Colors: LEDs and the Relationship Between CCT, CRI, Optical Safety, Material Degradation, and Photobiological Stimulation. Using an example dataset of 20 CALiPER-tested LED lighting products that cover the full range of market-available CCTs and CRIs, it separates myth from fact regarding the potential of LEDs to cause retinal damage, changes to artwork or other media, and stimulation of the human circadian system (which impacts health).

DOE Publishes CALiPER Report on Cost-Effectiveness of Linear (T8) LED Lamps

The U.S. Department of Energy's CALiPER program has released Report 21.3, which is part of a series of investigations on linear LED lamps. Report 21.3 details a set of life-cycle cost simulations that compared a two-lamp troffer using LED lamps (38W total power draw) or fluorescent lamps (51W total power draw) over a 10-year study period. The LED lamps were assumed to produce similar light output and light distribution when mounted inside the troffers, an assumption that was reasonable for less than a third of the products tested for this series of reports, but that may be more widely achievable in the near future, as SSL products advance.
