Definitions for fluorescent lamps

As used in this part, unless the context otherwise requires: "Compact fluorescent lamp" means a compact low-pressure, mercury-containing, electric-discharge light source in which a fluorescent coating transforms some of the ultraviolet energy generated by the mercury discharge into visible light, and includes the following characteristics: (1) One base (end cap) of any type, including but not limited to screw, bayonet, two pins, and four pins; (2) Integrally ballasted or non-integrally ballasted; (3) Light emission between a correlated color temperature of one thousand seven hundred Kelvin and twenty-four thousand Kelvin and a Duv of +0.024 and -0.024 in the International Commission on Illumination Uniform Color Space; (4) All tube diameters and all tube lengths; and (5) All lamp sizes and shapes for directional and nondirectional installations, including but not limited to plug-in, spiral, twin tube, triple twin, 2D, U-bend, and circular. "Linear fluorescent lamp" means a low-pressure, mercury-containing, electric-discharge light source in which a fluorescent coating transforms some of the ultraviolet energy generated by the mercury discharge into visible light, and includes all of the following characteristics: (1) Two bases (end caps) of any type, including but not limited to single-pin, two-pin, and recessed double contact; (2) Light emission between a correlated color temperature of one thousand seven hundred Kelvin and twenty-four thousand Kelvin and a Duv of +0.024 and -0.024 in the International Commission on Illumination Uniform Color Space; (3) All tube diameters, including but not limited to T5, T8, T10, and T12; (4) All tube lengths from 0.5 to eight feet, inclusive; and (5) All lamp shapes, including but not limited to linear, U-bend, and circular.
