They are the same as those used and discussed in Chapter 3 of the July 1997 Draft Report. For setting standards we would use the 10th percentile efficiency. Additionally, in calculating life cycle costs, the spreadsheet requires incremental ballast prices. The discussion below describes how we developed the ballast prices and incremental ballast prices.

Ballast Prices Because there are ballasts in the market at all of the efficiency levels considered by the Department for today's notice, we determined incremental ballast prices for various efficiency levels by collecting information in the marketplace. However, it is difficult to obtain end-user pricing. In most instances ballasts, either in fixtures or not in fixtures, are purchased by contractors from electrical distributors. The contractor installs the fixtures and/or ballasts in a building and bills the owner for the job. Thus the end-user ballast price is buried within the job invoice. To obtain end-user prices, the 1997 Report used ballasts prices derived from a data collection effort that Gough and Associates (G&A) conducted for LBNL by collecting data at points in the distribution chain where ballasts were sold as ballasts and applied mark-ups to estimate end-user prices. These markups, which were provided by respondents to a G&A survey of ballast and fixture manufacturers, were difficult to obtain and to verify. We reexamined the methodology used to obtain ballast prices for the 1997 report. DOE has decided to use a more direct approach where the starting price is closer to the end-user. By starting with Distributor to Contractor prices for ballasts in fixtures and not in fixtures, only one mark-up, segments G and H in the NEMA-provided ballast distribution channel chart (see Figure 1 below), is needed to arrive at the end-user price.

As described above, we have gathered new ballast price data from distributors of magnetic and electronic ballasts. There is now only one mark-up between the distributor selling price and the end-user price, for which we are using 13%. The department has used 13% contractor mark-up in past analyses, without any comment from stakeholders, and it was used by NEMA in material sent to DOE in July 1998

. We obtained prices for ballasts not in fixtures and for fixtures equipped with ballasts

. Ballasts not in fixtures are assumed to represent 37% of the market and ballasts in fixtures are assumed to represent 63% of the market

. These weights come from NEMA comment # 27 at 8 where 37% is for the distributor + LMC channel and 63% is for the OEM channel. With the goal of gathering ballast price data, LBNL attempted to contact two electrical distributors per state in late 1998 and January 1999. The first 26 distributors were taken from the Yellow Pages for 25 major metropolitan areas around the country. The remaining 74 electrical distributors were selected from the American Wholesalers & Distributers Directory (5th Ed, Holly M. Selden & Jane A. Malonis Editors, 1997 by Gale Research) After an initial phone call, letters of confidentiality along with a second sheet listing six fluorescent ballasts and six common fixtures were faxed to 60 distributors who said they would provide pricing information.

### & Jane A. Malonis Editors, 1997 by Gale Research) After an initial phone call, letters ofconfidentiality along with a second sheet listing six fluorescent ballasts and six common fixtures were faxed to 60 distributors who said they would provide pricing information.L S Depar tment of ner^U April .1.9.99 Each of these 60 distributors received a follow

-up call after the fax was sent. As of February 4, 1999, pricing data had been received from 27 electrical distributors in 19 different states. However, not all of the distributors provided prices for all six of the individual ballasts (not in fixtures) and for the six common fixtures equipped with these ballasts. Each distributor was asked to provide LBNL with a contractor price for each of the ballasts, assuming that the order would be for a quantity of 100 for any given ballast and was for a "good" client. Lower quantity purchases could result in higher prices and higher quantity purchases could result in lower prices. Table 1 below lists the six individual ballasts (not in fixtures) and the average of the prices we received from the distributors plus an assumed 13% contractor mark-up.

### We received more quotes than are listed in the table above. For T12 lamps, we only used prices from distributors who provided a price for both the magnetic and the electronic ballast. We did this because we wanted the most direct price differences between magnetic and electronic ballasts for T12 systems from the same source. For T8 lamps the full range of prices received were used to calculate the average. Each distributor was also asked to provide LBNL with a contractor price for six common fixtures equipped with the six fluorescent ballasts listed above. Again they were asked to assume that the order would be for a quantity of 100 for any given fixture and was for a "good" client. Table 2 below lists the common fixtures, each equipped with one or more of the six ballasts and the average of the prices we received from the distributors plus a 13% contractor mark-up. All of the fixtures for four-foot lamps are contractor grade recessed troffers with 277 volt ballasts and standard prismatic lenses. The fixtures for the eight-foot lamps are general purpose strip fixtures with 277 volt ballasts.

For T8 lamps the full range of prices received were used to calculate the average. NEMA also provided DOE with the results of their attempt to obtain ballast prices for ballasts sold in fixtures. NEMA asked fixture manufacturers for an estimate of the industry average differential in selling price from fixture manufacturer to distributors (segment D in NEMA's figure showing different channels from ballast manufacturer to end-user) between fixtures that were identical except for their ballasts. From these data, NEMA provided the Department with a ratio of the manufacturer price of a luminaire with electronic ballasts to one with magneticballasts. Then, using these data along with certain assumptions about fixture prices and markups, NEMA arrived at end-user prices for ballasts in fixtures. We have decided not to use this approach because the various assumptions are not documented, because fixture manufacturers were not asked to provide their own prices (which they would have known precisely) but instead what they estimated to be average prices for the entire industry, and because this approach does not provide any information about the range of possible prices. However, we did examine the results of the NEMA approach and found that the NEMA provided prices and ratios of fixture prices do fall within the ranges of data used in the analysis as discussed below.

average incremental ballast price for use in the LCC analysis

. We calculated the incremental price for an electronic ballast in a fixture by subtracting the price for a fixture equipped with a magnetic ballast from the price of the same fixture when equipped with an electronic ballast. The average of all the incremental prices is assumed to represent the incremental cost of the electronic ballast(s) in the fixture over and above the price of the baseline ballast 's average price. We used the T12 magnetic ballast price (not in a fixture) to be the baseline ballast since we cannot directly obtain the ballast portion of a fixture price

. We therefore made the assumption that the price of the baseline EEM ballast was the same whether sold by itself or as part of a fixture. This assumption affects the absolute ballast prices but does not affect the incremental price of an electronic ballast relative to a magnetic ballast. Given the above, the price of an electronic ballast is obtained as shown in Table 3 by the following: 

### Column 1 The average price of the magnetic (EEM) baseline ballast(s) not in fixture Column 2 The average price of the electronic ballast(s) not in fixture Column 3 The average incremental price for the electronic ballast(s) not in fixture, column

2 minus column I Column 4 The average price of the fixture associated with magnetic (EEM) ballast Column 5 The average price of the fixture equipped with an electronic ballast Column 6 The average incremental price for the electronically ballasted fixture, column 5

minus column 4 Column 7 Weighted electronic average incremental price - average incremental price of

electronic ballast not in fixture, column 3, multiplied by a weight of 0.37 plus average incremental price of electronic ballast not in fixture, column 6, multiplied by a weight of 0.63. Column 8 Weighted electronic average total price of electronic - weighted average

incremental electronic ballast price, column 7, added to the average price of the stand-alone EEM ballast, column 1. In the case of 3F40T12 and 3F32T8 tandem-wired electronic ballasts, the weighted price is 1.5 times the price of the corresponding 2-lamp electronic ballasts. This reflects the fact that existingwiring configurations will require three 2F40T12 or 2F32T8 electronic ballasts to be tandemwired between two 3-lamp fixtures. 

### The price for non-tandem wired 3F40T12 electronic ballasts is calculated by the same process as illustrated by the procedure above. However, in this case, the price of an EEM ballast (column 1) is actually the sum of the price for a 1F40T12 and a 2F40T12 EEM ballast.

Less Common Ballasts For the less common ballast types we were not able to directly obtain distributor prices. For these ballasts we went to a nation-wide supplier that stocks all of the less common ballasts and tend to receive orders for small quantities. In order to obtain pricing for the less common ballasts which would be comparable to the LBNL derived prices, we calculated the ratio between the average distributor price (from the LBNL prices) for the more common ballasts with the prices for them in the 1998/99 W. W. Grainger catalogue (number 389). For these ballasts, the prices and the ratios are in the first four rows of Table 4 below. Prices for the remaining ballasts in the table were adjusted by dividing the Grainger catalogue "Each "Price" by one of the ratios. All ballast prices in Table 4 are for ballasts sold separately, not as part of a fixture. Grainger's catalogue does not list fixtures equipped with these ballasts.

Ballast Price Variance The ballast prices we collected from distributors vary by location of the distributor and would likely also vary because of other factors (which we did not investigate) such as annual sales of the distributor, size of order, or time of data collection. Therefore, we have not used an average incremental price in the LCC analysis, but have used a range of prices. We have assumed that a large enough set of ballast prices would yield a normal distribution and have used a normal distribution for all of the incremental price input distributions for the LCC analysis. This was also done for the analysis in the July, 1997 Draft Report on ballasts. We chose a 15% standard deviation relative to the mean for all of the incremental price distributions used as inputs to the LCC analysis. Fifteen percent was also used in the July, 1997 report. We have also calculated the standard deviations for the larger sets of data we have for specific ballast types and find the assumed 15 percent standard deviation compares well with the data from Table 1. For example, the standard deviations of the 17 values of 2F40 T12/ES magnetic and electronic ballasts were 14% and 20% of their mean values, respectively. For the 21 values of 2F32T8 electronic ballast prices, we calculated a standard deviation of 14% of the mean value. Additionally, we tested the sensitivity of the LCC results to this input assumption (standard deviation) and found the results to be insensitive to the size of the standard deviation. As a result of this distribution, we are using the range of ballast prices shown in Table 6.

## *Pnces from Gramger catalog after adjusting It With pnceratIO ofGramgerto phone data for otherballasts for which ciata collected overphone was available (See Table 4). t Phone data collection

- Individual Ballast Price only (See Table I). :j: Phone data collection

- Price weighted byproportion ofballasts sold individually and those sold in fIxture (See Table 3).L: S. Department cif Energv .4pril 1999

Since incremental prices were used in the LCC analysis, we show, in the table below, the mean incremental ballast price and the range of incremental prices used for each lamp/ballast combination. For example, for the 2F40 T12/ES lamp, the mean incremental price to convert from the baseline EEM ballast to an electronic T12 ballast is $11.40, while the range of prices in the incremental ballast price distribution is from $6 .27 to $16.53.
