Outline of Investigation for Horticultural Lighting Equipment
|Publication Date:||17 April 2019|
The requirements contained in this outline of investigation apply to lighting equipment intended for use in a horticultural environment and installed in accordance with the U. S. National Electrical Code (NEC), ANSI/NFPA 70 and the Canadian Electrical Code, Part I (CEC), CSA C22.1.
Equipment covered by this outline of investigation is intended for horticultural lighting purposes and includes: horticultural luminaires, hardware and horticultural systems intended for use in a plant growth environment.
Lighting equipment that provides broadband white light such as light for general illumination, or whose primary purpose when applied to plantings is aesthetic and/or sustaining plant life is not considered horticultural lighting.
The photobiological safety assessment within this outline of investigation evaluates the light output characteristic of a single horticultural luminaire. Applicable cautionary or warning markings are then required on the product and in the installation and operating instructions. Increased exposure risk to facility personnel may be present depending upon the number of horticultural luminaires and their placement and/or positioning within the plant growth facility.
It is the responsibility of the plant growth facility to address the risks specified in 1.4 at the facility level and to ensure that people entering the plant growth areas while the lights are on, are aware of these risks and that appropriate safeguards are in place.
