Lighting in water treatment applications must provide adequate illumination that enhances worker safety, improves productivity, and reduces maintenance costs. In spaces with demanding environments, look for hazardous-rated luminaires with listings such as C1D1, C1D2, C2D1, and others. Well performing lighting solutions in these applications should include durable luminaires with precise optical control and uniform illumination, paired with controls, to reduce energy consumption and ensure these needs are met.
