We found that each type of ballast (i.e. electronic 2F40T12) exhibited a range of efficiencies in

the marketplace. The efficiencies shown above are the median (50 percentile) efficiencies which

were used for energy calculations. 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.

L S Department 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 individ ual 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.

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 magnetic

ballasts. 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.

prices do fall within the ranges of data used in the analysis as discussed below. 

Weighted Average Ballast Prices 

Having an average price for ballasts not in fixtures (Table I), we then determined an average 

price for ballasts in fixtures from the data in Table 2 and weighed them together to obtain an 
L'. S. Department of 'Enei gy _ April .1.1.19

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 ass umed 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 existing

wiring 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.

average incremental price of electronic ballast not in fixture, column 6, multiplied 

by a weight of 0.63. 

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 of3F40TI2 and 3F32T8 tandem-wired electronic ballasts, the weighted price is 1.5 

times the price of the corresponding 2-1amp electronic bailasts. This reflects the fact that existing 

wiring configurations will require three 2F40TI2 or 2F32T8 electronic ballasts to be tandemwired between two 3-1amp fixtures. 

The price for non-tandem wired 3F40TI2 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 IF40T12 and a 2F40TI2 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.

sensitivity of the Lee 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.

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.
