Current through September 30, 2024

Section 430.32 - Energy and water conservation standards and their compliance dates

The energy and water (in the case of faucets, showerheads, water closets, and urinals) conservation standards for the covered product classes are:

(a)Refrigerators/refrigerator-freezers/freezers. These standards do not apply to refrigerators and refrigerator-freezers with total refrigerated volume exceeding 39 cubic feet (1104 liters) or freezers with total refrigerated volume exceeding 30 cubic feet (850 liters). The energy standards as determined by the equations of the following table(s) shall be rounded off to the nearest kWh per year. If the equation calculation is halfway between the nearest two kWh per year values, the standard shall be rounded up to the higher of these values.

(1) The following standards apply to products manufactured on or before September 15, 2014, and before the 2029/2030 compliance dates depending on product class (see paragraphs (a)(2) and (3) of this section).

¹ This lamp type comprises of directional lamps. A directional lamp is a lamp that meets the definition of reflector lamp as defined in § 430.2 .

² This lamp type comprises of, but is not limited to, lamps that are pin base compact fluorescent lamps ("CFLs") and pin base light-emitting diode ("LED") lamps designed and marketed as replacements of pin base CFLs.

³ Indicates whether or not lamps are capable of operating in standby mode operation.

(C) The standards described in paragraph (dd)(1)(iv) of this section do not apply to a general service lamp that:

(1) Is a general service organic light-emitting diode (OLED) lamps (as defined in § 430.2 );

(2) Is a non-integrated lamp that is capable of operating in standby mode and is sold in packages of two lamps or less;

(3) Is designed and marketed as a lamp that has at least one setting that allows the user to change the lamp's correlated color temperature (CCT) and has no setting in which the lamp meets the definition of a colored lamp (as defined in § 430.2 ); and is sold in packages of two lamps or less;

(4) Is designed and marketed as a lamp that has at least one setting in which the lamp meets the definition of a colored lamp (as defined in § 430.2 ) and at least one other setting in which it does not meet the definition of colored lamp (as defined in § 430.2 ) and is sold in packages of two lamps or less; or

(5) Is designed and marketed as a lamp that has one or more component(s) offering a completely different functionality (e.g., a speaker, a camera, an air purifier, etc.) where each component is integrated into the lamp but does not affect the light output of the lamp (e.g., does not turn the light on/off, dim the light, change the color of the light, etc.), is capable of operating in standby mode, and is sold in packages of two lamps or less.
