⚖️ Seller Warranty & Marketplace Dispute Conciliation

The warranty should be activated if, after following all usage and troubleshooting instructions, the bulb exhibits a manufacturing defect, such as a battery failure that does not charge after the first use, internal circuit failure without signs of misuse, or if the filament has a defect that prevents operation. In such cases, the product may be considered defective, and the consumer is entitled to a replacement, repair, or refund.
