Products reported to provide supplemental lighting shall supplement daylight, which is the primary light source. These products shall be intended for applications where the lighting product is not the primary source of optical radiation for inducing photosynthesis, but is instead intended to supplement daylight and overall energy usage is not as high (e.g., a specialty lamp that is intended to provide specific spectra to induce a specific growth action in addition to daylight in a greenhouse or a higher output product with broadband spectra to fully supplement daylight in a northern environment).
