Buying Guide
What makes an explosion-proof exit light suitable for your site? Start with safety classifications (Class I/II, Division 1) and the environmental IP rating. Higher IP ratings mean better protection against dust and water, which matters in damp or dusty facilities. Battery backup duration is critical for staying lit during outages; plan for at least 90 minutes in smaller spaces and longer in larger areas.
Key considerations
- Environment: Indoor, damp, or outdoor; consider wet-location or explosion-proof models accordingly.
- Power source: Hardwired vs. battery-backup; assess maintenance needs and test frequency.
- Visibility: Sign size, lumen output, and distance from occupants influence escape route clarity.
- Compliance: UL, UL924, and other local codes; ensure proper certification for hazardous areas.
- Installation: Wall or ceiling mount options; ensure mounting hardware and accessibility for maintenance.
