(29) (A) The term “fluorescent lamp ballast” means a device which is used to start and operate fluorescent lamps by providing a starting voltage and current and limiting the current during normal operation. (B) The term “ANSI standard” means a standard developed by a committee accredited by the American National Standards Institute. (C) The term “ballast efficacy factor” means the relative light output divided by the power input of a fluorescent lamp ballast, as measured under test conditions specified in ANSI standard C82.2–1984, or as may be prescribed by the Secretary. (D) (i) The term “F40T12 lamp” means a nominal 40 watt tubular fluorescent lamp which is 48 inches in length and one-and-a-half inches in diameter, and conforms to ANSI standard C78.81–2003 (Data Sheet 7881–ANSI–1010–1). (ii) The term “F96T12 lamp” means a nominal 75 watt tubular fluorescent lamp which is 96 inches in length and one-and-a-half inches in diameter, and conforms to ANSI standard C78.81–2003 (Data Sheet 7881–ANSI–3007–1). (iii) The term “F96T12HO lamp” means a nominal 110 watt tubular fluorescent lamp which is 96 inches in length and one-and-a-half inches in diameter, and conforms to ANSI standard C78.81–2003 (Data Sheet 7881–ANSI–1019–1). (E) The term “input current” means the root-mean-square (RMS) current in amperes delivered to a fluorescent lamp ballast. (F) The term “luminaire” means a complete lighting unit consisting of a fluorescent lamp or lamps, together with parts designed to distribute the light, to position and protect such lamps, and to connect such lamps to the power supply through the ballast. (G) The term “ballast input voltage” means the rated input voltage of a fluorescent lamp ballast. (H) The term “nominal lamp watts” means the wattage at which a fluorescent lamp is designed to operate. (I) The term “power factor” means the power input divided by the product of ballast input voltage and input current of a fluorescent lamp ballast, as measured under test conditions specified in ANSI standard C82.2–1984, or as may be prescribed by the Secretary. (J) The term “power input” means the power consumption in watts of a ballast and fluorescent lamp or lamps, as determined in accordance with the test procedures specified in ANSI standard C82.2–1984, or as may be prescribed by the Secretary. (K) The term “relative light output” means the light output delivered through the use of a ballast divided by the light output delivered through the use of a reference ballast, expressed as a percent, as determined in accordance with the test procedures specified in ANSI standard C82.2–1984, or as may be prescribed by the Secretary. (L) The term “residential building” means a structure or portion of a structure which provides facilities or shelter for human residency, except that such term does not include any multifamily residential structure of more than three stories above grade. (M) The term “F34T12 lamp” (also known as a “F40T12/ES lamp”) means a nominal 34 watt tubular fluorescent lamp that is 48 inches in length and 1½ inches in diameter, and conforms to ANSI standard C78.81–2003 (Data Sheet 7881–ANSI–1006–1). (N) The term “F96T12/ES lamp” means a nominal 60 watt tubular fluorescent lamp that is 96 inches in length and 1½ inches in diameter, and conforms to ANSI standard C78.81–2003 (Data Sheet 7881–ANSI–3006–1). (O) The term “F96T12HO/ES lamp” means a nominal 95 watt tubular fluorescent lamp that is 96 inches in length and 1½ inches in diameter, and conforms to ANSI standard C78.81–2003 (Data Sheet 7881–ANSI–1017–1). (P) The term “replacement ballast” means a ballast that— (i) is designed for use to replace an existing ballast in a previously installed luminaire; (ii) is marked “FOR REPLACEMENT USE ONLY”; (iii) is shipped by the manufacturer in packages containing not more than 10 ballasts; and (iv) has output leads that when fully extended are a total length that is less than the length of the lamp with which the ballast is intended to be operated.
