If a defect occurs within warranty, please provide photos/videos and the order details / item code so we can verify the claim. For small quantities, we typically arrange replacement units with your next order to reduce freight cost. For batch issues, we will trace the production batch, investigate root cause, and agree on a solution—replacements in the next shipment or another after-sales plan based on the situation.

We follow a multi-stage QC process from incoming materials to final shipment. First, key materials and electronic components (including LED chips) are inspected and pre-aged before production. During manufacturing, semi-finished units are tested to catch issues early. We also run reliability tests such as high/low temperature, waterproof, vibration, and anti-interference testing where applicable. Every finished product then undergoes final aging and inspection, and we perform a final quality check before shipment.

Our LED work lights and light bars are built to an IP67 waterproof level. Selected models also feature a waterproof breather valve to help equalize pressure and reduce moisture buildup in demanding environments.

Our LED work lights and light bars go through anti-interference testing before shipment to help ensure minimal EMI/RFI impact in real-world use. Test results and compliance documents may vary by model—please confirm with your sales contact.
