Forest Lighting, the USA division of global LED manufacturing leader MLS, announced it has received certification from The National Sanitation Foundation (NSF International) covering its T8 LED tube 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.

The U.S. Department of Energy's CALiPER program has released Report 21.2, which is part of a series of investigations on linear LED lamps. Report 21.2 focuses on the performance of three linear (T8) LED lamps and a benchmark fluorescent lamp in five different troffer types. Also included are the results of a subjective evaluation. The LED lamps were intended as alternatives to T8 fluorescents and were chosen for the study primarily based on their luminous intensity distributions (narrow, medium, and wide beam angles).

The U.S. Department of Energy's CALiPER program has released an Application Summary Report that focuses on the bare-lamp performance of 31 linear LED lamps intended as an alternative to T8 fluorescent lamps.
