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.
