AI-Powered supplier vetting

SummaryThe supplier operates in LED optoelectronic products, components, displays, lamps, accessories, smart-home products, and related software. It reports R&D, production, sales, 3D software design, ODM, OEM, and multiple customization capabilities, including customization from samples and designs. Production information includes 50 LED strip-light lines, monthly sales exceeding 8 million meters, a stated stock of 5 million meters, and integrated information-system controls with AOI and crystal solid-state testing. However, quality and service governance appears weakly documented: only one quality inspector is reported, finished products are checked by packing staff, and there are no written procedures or records for service assessment, corrective actions, or complaint handling. No certification, formal customer cases, overseas service network, or financial strength evidence is provided. The supplier has exported for 10 years and offers multiple trade and payment terms, but lead times and service arrangements...

Supplier typeThe supplier is a manufacturer and R&D-oriented LED business covering LED strips, displays, lamps, accessories, optoelectronic components, sensors, semiconductor-chip-related activities, and smart-home products. Its description states that it integrates R&D, production, and sales, while also providing ODM and OEM services.

After-Sales capabilityThe supplier states that training is part of its overseas service offering, but it has no overseas showroom, agents, branches, offline trade-show participation, or identified overseas service countries. Complaint handling, service assessment, and corrective/preventive-action processes have no written procedures or records, indicating limited documented after-sales governance.

R&D capabilityThe supplier reports R&D capability, at least one new product during the past year, 3D software design, ODM services, smart-home and control-program R&D, and integrated information-system manufacturing. It also reports AOI and crystal solid-state testing, although no SDK is available; overall evidence supports active product and process development.

Production capacityThe supplier reports 50 LED strip-light production lines, monthly sales exceeding 8 million meters, stock of 5 million meters, and integrated production-to-logistics information systems. It states three-day delivery for stocked core products, off-season lead time within 15 working days, and peak-season lead time of one month; however, quality inspection is reported as one inspector and finished products are checked by packing staff.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. It also provides 3D software design, ODM, and OEM services, with a broad range of voltage, color-temperature, and color-model options.

Product Q&A

Q:What is the difference between COB LED strip and SMD LED strip?

COB strips have higher brightness, more uniform light (no dark spots), and better heat dissipation. SMD strips are more flexible in installation for small spaces.

Q:What voltages are available for your COB LED strips?

We offer 5V, 12V, 24V, 110V and 220V, which can meet different usage scenarios.

Q:Can COB LED strips be cut?

Yes, most of our COB strips can be cut along the marked cutting lines, without affecting the normal use of the remaining part.

Q:What is the delivery time?

We have 5 million meters of stock for core products, ensuring delivery within 3 days after order confirmation. For bulk orders, delivery time is 7-15 days.

Q:Which logistics companies do you cooperate with?

We cooperate with DHL, FedEx, UPS and other international logistics companies, and can also arrange logistics according to your requirements.
