Industrial lighting specification sheets often contain classifications and certifications that indicate where a fixture can be safely installed. Class 1 refers to flammable gases, Class 2 to combustible dust, and Class 3 to ignitable fibers, while Divisions and Zones describe how frequently the hazard may occur. Standards such as UL 844, CSA, ATEX, and IECEx confirm that equipment has been evaluated for specific hazardous applications. Knowing the difference between location classifications and product certifications is essential for choosing safe, compliant lighting.

Emergency lighting is critical in industrial and hazardous environments, helping personnel evacuate safely and shut down dangerous processes during power outages. Codes generally require systems to activate automatically within 10 seconds, operate for at least 90 minutes, provide adequate illumination, undergo regular testing, and be certified for hazardous locations. Red Sky Lighting’s RDX EM Series exceeds these standards with up to 180 minutes of runtime, outputs from 6,000 to 29,000 lumens, and reliable operation in temperatures up to 140°F (60°C).
