Exit light

When selecting Exit Lights, prioritize LED technology for energy efficiency and a lifespan of at least 50,000 hours. Ensure the unit includes a built-in Ni-Cd or LiFePO4 backup battery capable of providing at least 90 to 120 minutes of emergency illumination during power outages. The housing should be made of fire-retardant ABS plastic or high-grade aluminum to withstand high temperatures.

Compliance is critical for safety products. For the US market, ensure products are UL 924 listed. For European markets, look for CE (EN 60598-2-22) and RoHS certification. If exporting to Australia, AS/NZS 2293 is mandatory. Always verify that the IP rating (e.g., IP65) is appropriate if the lights are intended for outdoor or high-moisture environments.

For industrial warehouses, choose high-lumen output and vibration-resistant fixtures. In commercial offices, slim-profile edge-lit acrylic panels are preferred for aesthetics. For hazardous environments (like chemical plants), you must source explosion-proof certified exit signs to prevent ignition risks.

Look for units with a Self-Diagnostic (Auto-Test) function, which automatically performs monthly and annual tests to ensure battery and lamp integrity. Additionally, ensure the presence of a manual test button and LED status indicator for easy maintenance checks by facility managers.

Request a sample for destructive testing and verify the battery production date to ensure they haven't been sitting in storage for too long. Use third-party inspection services like SGS or Intertek to conduct a Pre-Shipment Inspection (PSI), focusing on the emergency switch-over time and battery duration.

Negotiate for a warranty period of at least 3 to 5 years, covering both the LEDs and the battery. Discuss MOQ flexibility for customized signage (e.g., specific languages or pictograms). Ask for tiered pricing where a 20% increase in volume could lead to a 5-10% unit cost reduction.

Exit lights contain batteries, which are classified as Dangerous Goods (UN3481 or UN38.3). Ensure the supplier provides a Material Safety Data Sheet (MSDS) and a Non-Dangerous Goods Declaration for sea freight. For air freight, strict IATA packaging regulations must be followed to avoid customs delays or fines.

Always conduct transactions through secure payment channels and consider using Trade Terms like FOB (Free On Board) to maintain control over the main carriage and insurance. Verify the supplier's Audited Supplier status on Made-in-China.com to confirm their factory existence and production capacity.
