(2) (a) "Compact fluorescent lamp" means a compact, low-pressure, mercury-containing, electric-discharge light source:

(I) In which a fluorescent coating transforms some of the ultraviolet energy generated by the mercury discharge into visible light; and

(II) That:

(A) Includes one base or end cap of any type, including screw, bayonet, two-pin, or four-pin;

(B) Is integrally ballasted or nonintegrally ballasted;

(C) Emits light between a correlated color temperature of 1700 Kelvin and 24000 Kelvin and a Duv of +0.024 and -0.024 in the CIECAM02-UCS; and

(D) Includes one or more tubes, which may be of any diameter or length.

(b) "Compact fluorescent lamp" includes lamps of all sizes and shapes for directional and nondirectional installations, including plug-in, spiral, twin tube, triple twin, 2D, U-bend, and circular lamps, that satisfy the description in subsection (2)(a) of this section.

(3) "Duv" means delta (u, 2/3v'), which is a metric that describes the distance of a light color point from the planckian locus.

(4) "Executive director" means the executive director of the department of public health and environment or the executive director's designee.

(5) (a) "Linear fluorescent lamp" means a low-pressure, mercury-containing, electric-discharge light source:

(I) In which a fluorescent coating transforms some of the ultraviolet energy generated by the mercury discharge into visible light; and

(II) That:

(A) Includes two bases or end caps of any type, including single-pin, two-pin, or recessed double contact;

(B) Emits light between a correlated color temperature of 1700 Kelvin and 24000 Kelvin and a Duv of +0.024 and -0.024 in the CIECAM02-UCS;

(C) Includes all tube diameters, including T5, T8, T10, and T12 tubes; and

(D) Includes all tube lengths from six inches to eight feet.

(b) "Linear fluorescent lamp" includes lamps of all shapes, including linear, U-bend, and circular.

(6) "Sunlamp product" has the meaning set forth in 21 CFR 1040.20 (b)(9).
