Chapter 60.1
Fluorescent Lamp Ballast Standards

§ 42-60.1-2. Definitions.

In this chapter the following words and phrases shall have the following meanings:

(1) “Ballast efficiency factor” (BEF) means

where relative light output and power input shall be determined by manufacturers’ testing in accordance with the standard ANSI C 32.2-1984.

(2) “Director” means director of the governor’s office of energy assistance.

(3) “Fluorescent lamp ballast” or “ballast” means a device designed to operate fluorescent lamps by providing a starting voltage and current, and limiting the current during normal operation, but does not include devices that have a dimming capability or are intended for use in ambient temperatures of zero degrees Fahrenheit or less, or have a power factor of less than .60 for a single F40T12 lamp.

(4) “F40T12 lamp” means a tubular fluorescent lamp that is a nominal forty (40) watt lamp with a forty-eight (48) inch tube length and one and one-half (1½) inches in diameter.

(5) “F96T12 lamp” means a tubular fluorescent lamp that is a nominal seventy-five (75) watt lamp with a ninety-six (96) inch tube length and one and one-half (1½) inches in diameter.

(6) “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 these lamps, and to connect these lamps to the power supply.

(7) “New appliance” means an appliance that is sold, offered for sale, or installed for the first time and specifically includes floor models and demonstration units.

(8) “Nominal input voltage” means an input voltage within plus five percent (5%) or minus five percent (5%) of a specified value.

(9) “Nominal lamp watts” means the wattage at which a lamp is designed to operate and for which it is therefore rated.

(10) “Relative light output” means the test ballast light output divided by a reference ballast light output using the same reference lamp and expressing the value as a percent. These measurements are made at the ballast’s rated primary voltage.
