In a recent column for ELECTRICAL CONTRACTOR, I provided an update on the 179D energy efficiency tax deduction, ENERGY STAR V.2 Lamps criteria and V.2 Luminaires criteria, and metal halide rules taking effect.

A recent blog post on tEDmag.com talks about a more recent Department of Energy ruling on general service lamps, in which DOE expanded the definition of lamps that will face energy standards in 2020. This was a curious ruling. DOE appears to remove several significant lamp exemptions, while appearing to include reflector lamps, which are separately regulated. Meanwhile, DOE did not produce new energy standards by the deadline, which means, according to the language of the Energy Independence and Security Act of 2008, that general service lamps will face a backstop energy standard of 45 lumens/W in 2020. This situation appears to be in flux, and I’ll cover it in detail as the situation becomes more clear.
