The process varies by supplier, but the honest answer is that cross-border warranty claims are more logistics than law. A reputable supplier will:
1. Require photo/video evidence of the failure + a brief description of the installation conditions
2. Ship replacement product with your next order (consolidated shipping — you're not paying air freight for two panel lights)
3. Or, for larger failures (e.g., a batch issue affecting multiple fixtures), arrange a separate replacement shipment at their cost
What they won't do: refund you cash, cover the labor cost to replace a failed fixture on-site, or air-freight a single replacement unit for free. The warranty covers the product, not the installation cost incurred to access it.
The practical protection, beyond the warranty clause, is to order 2–3% spare units with every shipment. At typical LED failure rates, that buffer covers you for years, and spare units shipped with the original container cost nothing extra in freight. If your project has zero tolerance for dark fixtures (hospital, 24/7 operation), carry 5% spares and treat them as insurance, not waste.
We honor our warranty terms and make the replacement process straightforward. Most claims we see are for driver failures (as expected — the driver is the statistical failure point, not the LED) and are resolved by shipping replacement drivers with the customer's next order.
