‘‘(9) Test procedures for illuminated exit signs shall 
be based on the test method used under Version 2.0 of 
the Energy Star program of the Environmental Protection 
Agency for illuminated exit signs. 
‘‘(10) Test procedures for distribution transformers 
and low voltage dry-type distribution transformers shall 
be based on the ‘Standard Test Method for Measuring the 
Energy Consumption of Distribution Transformers’ pre-
scribed by the National Electrical Manufacturers Associa-
tion (NEMA TP 2–1998). The Secretary may review and 
revise this test procedure. For purposes of section 346(a), 
this test procedure shall be deemed to be testing require-
ments prescribed by the Secretary under section 346(a)(1) 
for distribution transformers for which the Secretary 
makes a determination that energy conservation standards 
would be technologically feasible and economically justi-
fied, and would result in significant energy savings. 
‘‘(11) Test procedures for traffic signal modules shall 
be based on the test method used under the Energy Star 
program of the Environmental Protection Agency for traf-
fic signal modules, as in effect on the date of enactment 
of this paragraph. 
‘‘(12) Test procedures for medium base compact fluo-
rescent lamps shall be based on the test methods used 
under the August 9, 2001, version of the Energy Star pro-
gram of the Environmental Protection Agency and De-
partment of Energy for compact fluorescent lamps. Cov-
ered products shall meet all test requirements for regu-
lated parameters in section 325(bb). However, covered 
products may be marketed prior to completion of lamp life 
and lumen maintenance at 40 percent of rated life testing 
provided manufacturers document engineering predictions 
and analysis that support expected attainment of lumen 
maintenance at 40 percent rated life and lamp life time. 
‘‘(13) The Secretary shall, not later than 18 months 
after the date of enactment of this paragraph, prescribe 
testing requirements for ceiling fans and ceiling fan light 
kits.’’; and 
(2) by adding at the end the following: 
‘‘(f) ADDITIONAL
CONSUMER
AND
COMMERCIAL 
PRODUCTS.—The Secretary shall, not later than 24 
months after the date of enactment of this subsection, pre-
scribe testing requirements for suspended ceiling fans, re-
frigerated bottled or canned beverage vending machines, 
and commercial refrigerators, freezers, and refrigerator-
freezers. Such testing requirements shall be based on ex-
isting test procedures used in industry to the extent prac-
tical and reasonable. In the case of suspended ceiling fans, 
such test procedures shall include efficiency at both max-
imum output and at an output no more than 50 percent 
of the maximum output.’’. 
(c) NEW STANDARDS.—Section 325 of the Energy 
Policy and Conservation Act (42 U.S.C. 6295) is amended 
by adding at the end the following: 
‘‘(u) BATTERY CHARGER AND EXTERNAL POWER 
SUPPLY ELECTRIC ENERGY CONSUMPTION.—
‘‘(1) INITIAL RULEMAKING.—(A) The Secretary 
shall, within 18 months after the date of enactment 
of this subsection, prescribe by notice and comment, 
definitions and test procedures for the power use of 
battery chargers and external power supplies. In es-
tablishing these test procedures, the Secretary shall 
consider, among other factors, existing definitions 
and test procedures used for measuring energy con-
sumption in standby mode and other modes and as-
sess the current and projected future market for 
battery chargers and external power supplies. This 
assessment shall include estimates of the significance 
of potential energy savings from technical improve-
ments to these products and suggested product 
classes for standards. Prior to the end of this time 
period, the Secretary shall hold a scoping workshop 
to discuss and receive comments on plans for devel-
oping energy conservation standards for energy use 
for these products. 
‘‘(B) The Secretary shall, within 3 years after 
the date of enactment of this subsection, issue a 
final rule that determines whether energy conserva-
tion standards shall be issued for battery chargers 
and external power supplies or classes thereof. For 
each product class, any such standards shall be set 
at the lowest level of energy use that—
‘‘(i) meets the criteria and procedures of 
subsections (o), (p), (q), (r), (s), and (t); and 
‘‘(ii) will result in significant overall an-
nual energy savings, considering both standby 
mode and other operating modes. 
‘‘(2) REVIEW
OF
STANDBY
ENERGY
USE
IN 
COVERED PRODUCTS.—In determining pursuant to 
section 323 whether test procedures and energy con-
servation standards pursuant to this section should 
be revised, the Secretary shall consider, for covered 
products that are major sources of standby mode en-
ergy consumption, whether to incorporate standby 
mode into such test procedures and energy conserva-
tion standards, taking into account, among other 
relevant factors, standby mode power consumption 
compared to overall product energy consumption.
