''Freezer'', a cabinet designed as a unit for the storage of food at temperatures of approximately zero degrees fahrenheit, having the ability to freeze food and having a source of refrigeration requiring an energy input.

''F40T12 lamp'', a tubular fluorescent lamp that is a nominal forty watt lamp with a forty-eight inch tube length and one and one-half inches in diameter.

''F96T12 lamp'', a tubular fluorescent lamp that is a nominal seventy-five watt lamp with a ninety-six inch tube length and one and one-half inches in diameter.

''Lamp'', an incandescent, reflector incandescent, tungsten halogen, or fluorescent type lamp.

''Luminaire'', 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.

''Medium voltage dry-type distribution transformer'', a transformer that: (1) has an input voltage of more than 600 volts but less than or equal to 34,500 volts; (2) is air-cooled; (3) does not use oil as a coolant; and (4) is rated for operation at a frequency of 60 Hertz.

''Metal halide lamp'', a high-intensity discharge lamp in which the major portion of the light is produced by radiation of metal halides and their products of dissociation, possibly in combination with metallic vapors.

''Metal halide lamp fixture'', a light fixture designed to be operated with a metal halide lamp and a ballast for a metal halide lamp.

''New appliance'', an appliance that is sold, offered for sale or installed for the first time and specifically includes floor models and demonstration units.

''Probe-start metal halide ballast'', a ballast used to operate metal halide lamps which does not contain an igniter and which instead starts lamps by using a third starting electrode probe in the arc tube.

''Refrigerator'', a cabinet with one exterior door designed for the refrigerated storage of food at temperatures above thirty-two degrees fahrenheit and having a source of refrigeration requiring an energy input; refrigerator may include a compartment for the freezing and storage of food at temperatures below thirty-two degrees fahrenheit but does not provide a separate low temperature compartment designed for the freezing and long term storage of food at temperatures below eight degrees fahrenheit. A refrigerator may have interior doors on compartments.

''Refrigerator-freezer'', a cabinet which consists of two or more compartments with at least one of the compartments designed for the refrigerated storage of foods at temperatures above thirty-two degrees fahrenheit and with at least one of the compartments designed for the freezing and storage of foods at temperatures of eight degrees fahrenheit or below. The source of refrigeration requires energy input.

''Residential furnace or boiler'', a product which utilizes only single-phase electric current, or single-phase electric current or DC current in conjunction with natural gas, propane, or home heating oil, and which:-

(1) is designed to be the principle heating source for the living space of a residence;

(2) is not contained within the same cabinet with a central air conditioner with a rated cooling capacity exceeding 65,000 Btu per hour;

(3) is an electric central furnace, electric boiler, forced-air central furnace, gravity central furnace or low-pressure steam or hot water boiler; and

(4) has a heat input rate of less than 300,000 Btu per hour for electric boilers and low-pressure steam or hot water boilers, and less than 225,000 Btu per hour for forced-air central furnaces, gravity central furnace and electric central furnaces.

''Single-voltage external AC to DC power supply'', a device that:

(1) is designed to convert line voltage AC input into lower voltage DC output;

(2) is able to convert to only one DC output voltage at a time;

(3) is sold with, or intended to be used with, a separate end-use product that constitutes the primary power load;

(4) is contained within a separate physical enclosure from the end-use product;

(5) is connected to the end-use product via a removable or hard-wired male/female electrical connection, cable, cord or other wiring;

(6) does not have batteries or battery packs, including those that are removable, that physically attach directly to the power supply unit;

(7) does not have a battery chemistry or type selector switch and indicator light, or does not have a battery chemistry or type selector switch and a state of charge meter; and

(8) has a nameplate output power less than or equal to 250 watts.

''State-regulated incandescent reflector lamp'', a lamp, not colored or designed for rough or vibration service applications, with an inner reflective coating on the outer bulb to direct the light, an E26 medium screw base, a rated voltage or voltage range that lies at least partially within 115 to 130 volts and that falls into either of the following categories: a bulged reflector, elliptical reflector, blown parabolic aluminized reflector or similar bulb shape with a diameter equal to or greater than 2.25 inches; or a reflector, parabolic aluminized reflector, bulged reflector or similar bulb shape with a diameter of 2.25 to 2.75 inches, inclusive.
