SLP manufactures lighting fixture components, primarily for industrial applications. One key branch of industrial lighting is food processing. As such, many of SLP’s components are designed to be utilized in food processing plants. To make that happen, these components require certification from NSF International.

NSF (National Sanitation Foundation) International is a global independent organization that develops public health standards for products in the food, water, health science and consumer goods industries. When SLP designs a fixture component for possible application in the food industry, the component is submitted to NSF for evaluation and testing to the Food Equipment Certification standard. Typically, luminaires in this standard are tested for usage in Splash Zones (areas exposed to routine soiling from splashes and spills, but are not surfaces intended for contact with consumable food), as well as Nonfood Zones (areas not exposed to food or splashes, but may be subject to minor dirt and debris). Some key criteria that NSF focuses on are surface smoothness, cleanability, and corrosion resistance.

Among the SLP fixture component lines that are NSF certified are the Citadel Round, Citadel 4/4i/4s, Citadel 2/Narrow4’, as well as the Remote Box Enclosure.
