Let's Talk About Your Project

MOQ varies by product type. For standard lighting fixtures, MOQ typically starts from 50-200 units depending on the model. For custom OEM modules, MOQ is discussed based on tooling, materials, and production requirements. Contact us with your specific product and we'll provide a clear answer.

Yes. We regularly work from customer-supplied drawings, samples, renderings, or application descriptions. Our engineering team evaluates structural fit, thermal management, power supply, and optical requirements, then proposes a development path. Send us your materials and we'll review feasibility at no charge.

Standard product samples are typically available within 3-7 business days. Custom OEM module samples depend on the complexity of the design -- initial prototypes usually take 10-20 business days after specification confirmation. We'll give you a specific timeline once we understand your requirements.

Depending on the product and target market, we can support CE, RoHS, REACH, CB, UL/ETL, SAA, and other market-specific certifications. Tell us your target market and project requirements and we'll confirm what certification documentation is available or can be arranged.

We follow a structured QC process that includes incoming material inspection, in-process monitoring, functional and electrical testing, appearance inspection, and final pre-shipment verification. For OEM projects, we lock in approved specifications and component sources before mass production begins to ensure consistency.

Standard warranty is 3 to 5 years depending on the product grade and component selection. For quality issues, we focus on root-cause analysis and practical corrective action, including replacement parts or product exchange where applicable. Warranty terms are confirmed in writing before order placement.
