levels established for the analysis are determined based on the market distribution of existing products in other words, based on the range of efficiencies and efficiency level clusters that already exist on the market. Using the design option approach, the efficiency levels established for the analysis are determined through detailed engineering calculations and/or computer simulations of the efficiency improvements from implementing specific design options that have been identified in the technology assessment.
DOE may also rely on a combination of these two approaches. For example, the efficiency-level approach based on actual products on the market may be extended using the design option approach to interpolate to define gap fill levels to bridge large gaps between other identified efficiency levels and/or to extrapolate to the max-tech level particularly in cases where the maxtech level exceeds the maximum efficiency level currently available on the market.
In the January 2016 Final Rule DOE
used an efficiency-level approach, determining efficiency levels based generally on commercially available lamps that incorporate the design options identified in the technology assessment and screening analysis. 81
FR 580, 592. For each established product class, DOE selects a baseline model as a reference point against which any changes resulting from new or amended energy conservation standards can be measured. The baseline model in each product class represents the characteristics of common or typical products in that class. Typically, a baseline model is one that meets the current minimum energy conservation standards and provides basic consumer utility. The current standards for CFLKs are based on efficacy and are found at 10 CFR
430.32s6.

Issue 19: DOE requests feedback on whether the current established energy conservation standards are appropriate baselines for CFLKs to evaluate whether to amend the current energy conservation standards for these products.
Issue 20: DOE requests data and information regarding the most common models of CFLKs i.e. whether they use lamps or integrated SSL circuitry, the number of light sources, the total lumen output of the fixture, etc.. DOE requests information on the percent of CFLKs that have sockets for lamps versus the percent that have integrated SSL
circuitry.
Issue 21: DOE requests feedback on the common characteristics of light sources found in CFLKs i.e., technology, base type, wattage, efficacy, color rendering index CRI, correlated color temperature CCT, and lifetime. DOE requests information on the percent of CFLKs with sockets that are shipped with CFLs versus LED
lamps.
Issue 22: DOE requests feedback on the appropriate baseline models for any newly analyzed product classes that are not currently in place, as discussed in section II.B.1 of this document. For newly analyzed product classes, DOE
requests energy use data to develop a baseline relationship between energy use and adjusted volume.
In the January 2016 Final Rule, DOE
selected a baseline and more-efficacious substitutes taking into consideration two different substitution scenarios: 1
A lamp replacement scenario and 2 a light kit replacement scenario i.e., accounting for changes to the fixture. In both scenarios, the baseline lamp was kept the same and the baseline fixture was assumed to have the most common total socket number of two for CFLKs.
In the lamp replacement scenario, the more-efficacious substitute was required to have the same base type as the baseline lamp and no changes to the
fixture were made. In the light kit replacement scenario, a moreefficacious fixture was chosen, allowing for a more-efficacious lamp substitute with a different base type than the baseline lamp and with a different number of sockets than the baseline fixture. For additional discussion of the baseline selected for the January 2016
Final Rule, see chapter 5 of the January 2016 Final Rule TSD. 81 FR 580, 594
595.
In the January 2016 Final Rule, DOE
ensured potential substitutions maintained lumen output within 10
percent of the baseline lamp lumen output for the lamp replacement scenario and within 10 percent of the baseline fixture lumen output for the light kit replacement scenario. 81 FR
580, 594. In the January 2016 Final Rule TSD, DOE ensured that a wide variety of design options would be available at all efficacy levels ELs e.g., E12, E17, and G9 bases and candle, flame tip, and torpedo shapes. DOE also ensured that dimmable lamps and lamps with a range of CCTs and lumen packages were available at all ELs. Further, DOE
confirmed that CFLKs with consumerreplaceable and non-consumer replaceable LED modules and drivers would meet EL 3. See chapter 5 of the January 2016 Final Rule TSD.
In the January 2016 Final Rule, DOE
developed a continuous equation to establish ELs, specifying a minimum lamp efficacy for a lumen package. To develop the general form of the equation, DOE evaluated lamps with similar characteristics, such as technology, bulb shape, and lifetime, across a range of lumen outputs. 81 FR
580, 596.
The maximum available efficacies analyzed in the January 2016 Final Rule are provided in Table II.5 and Table II.6
of this document. The maximum available efficacy level is the highest efficacy unit currently available on the market.
