(a) General lighting standard for commercial kennels. Lighting in commercial kennels may be provided by natural or artificial light, or both. Whether lighting is provided by natural or artificial light, or both, the following standards shall be met:

1. (1) There shall be ample lighting by natural or artificial means to provide sufficient illumination to allow routine inspection of the kennel, housing facility and primary enclosures and observation of the dogs at any time and to assure proper cleaning and good housekeeping practices and for the well-being of the dogs.
2. (2) Lighting shall be uniformly diffused throughout the kennel and housing facility where a dog is housed, kept or present, including primary enclosures.
3. (3) All areas of the kennel and housing facility in which a dog is housed, kept or present, including primary enclosures, shall be provided a regular diurnal cycle through natural or artificial light, or both.
4. (4) The lighting range provided during the 12-hour light period of the diurnal cycle shall be 40 to 60 foot candles or 430—650 lux, in all areas and rooms of the kennel and kennel housing facility, including primary enclosures, where a dog is housed, kept or present.
5. (5) Primary enclosures and other areas of the kennel and kennel housing facility in which a dog is housed, kept or present shall be placed or located in a manner that protects each dog from exposure to excessive light.

(b) Specific lighting standards. The following specific standards are in addition to, not in place of, all other requirements meeting the general lighting standards established in this section. The following specific standards apply:

1. (1) Natural light. Where kennel and housing facility lighting is provided by natural light, any window or opening, with the exception of the openings that provide for unfettered access to the exercise area, which provides natural light shall be covered with a transparent material such as glass or hard plastic and remain unobstructed.

   1. (i) The artificial lighting shall be provided by full spectrum lighting.
   2. (ii) Lighting sources and systems shall be kept in good repair and functional and may not have any bulb or part of the system in disrepair, such as being unable to produce light, burned out or emitting irregular bursts of light, such as when a ballast is in disrepair.
   3. (iii) Light sources, whether their primary purpose is to provide heat or light, shall be provided in a manner that prevents dogs from being injured (that is, through contact with the light, fixture, bulb, switch or cord or through electrocution).
