About Greatwall LED Light Co., Ltd. - Light Emitting Diode Supplier in China

Greatwall LED Light Co., Ltd. operates from China and currently lists seven active LED lighting products. The catalogue includes four‑foot LED tube lights ranging from 16 W to 18 W, several models with UL or UL DLC certification, a microwave‑sensor variant, and two golf‑ball‑shaped LED bulbs in 12 W and 3 W with E26/E27/B22 bases. Each tube is described as a 4 ft unit, and the bulbs are identified by their base type and wattage, reflecting a focused product line within the Light Emitting Diode category.

The listed items fall under the electrical equipment chapter of the HS system, typically classified in HS‑84 (e.g., 8541.40 for LED tubes and 8541.10 for LED bulbs). The product set demonstrates compliance with common safety standards such as UL and UL DLC, which are frequently required by importers in North America and Europe. By offering both standard and sensor‑controlled tubes, the supplier addresses commercial lighting applications in offices, retail spaces, and industrial facilities.

Product Range and Specialties of Greatwall LED Light Co., Ltd.

The catalogue provides four‑foot LED tubes in 16 W and 18 W configurations, with variants that include full PC covers, UL certification, UL DLC approval, and integrated microwave sensors. Additionally, the supplier lists two golf‑ball‑shaped LED bulbs, one 12 W model and one 3 W model, available with E26, E27, and B22 bases. In the LED lighting market, 4 ft tubes are commonly produced as T8 or T5 form factors, delivering efficacy between 90 and 110 lm/W and a colour rendering index (CRI) of 80 or higher. Bulbs of the golf‑ball shape are typically used for retrofit applications, offering a compact aluminium housing, a glass or polycarbonate diffuser, and compliance with IEC 60721 for environmental testing.

Industry practice for these product types includes offering a range of lumen outputs (approximately 1,200 lm for 16 W tubes and 1,350 lm for 18 W tubes) and providing detailed photometric curves. Buyers also expect options such as dimmable drivers, IP20 or IP44 protection ratings, and packaging that meets IEC 62040 for electromagnetic compatibility. The supplier’s focus on UL‑certified models aligns with the standard safety verification required for commercial lighting equipment in many export markets.

Trade and Export Information - Greatwall LED Light Co., Ltd.

China remains a major exporter of LED lighting, with shipments typically routed to Europe, North America, the Middle East, and Southeast Asia. LED tubes and bulbs are classified under HS chapter 85, where customs authorities often request test reports for UL, CE, or RoHS compliance. Importers frequently require a Certificate of Conformity (CoC) and a Declaration of Conformity (DoC) for each shipment, especially when the goods are destined for the EU or the United States. Standard logistics involve loading the tubes in cardboard cartons (usually 20 pcs per box) and the bulbs in smaller poly‑bag packs, then consolidating into 20‑ft or 40‑ft containers. FOB Shanghai or Ningbo and CIF Rotterdam or New York are common Incoterms used for these products.

Typical buyers include commercial lighting contractors, facility managers, and wholesale distributors who look for energy‑efficient retrofits. Because the catalogue emphasizes UL and UL DLC approvals, the supplier is positioned to meet the safety and performance expectations of markets that enforce strict electrical standards. Export documentation often includes the commercial invoice, packing list, test certificates, and, where required, a phytosanitary or customs declaration for electronic components.

Sourcing from Greatwall LED Light Co., Ltd. - Buyer Guidance

When evaluating Greatwall LED Light Co., Ltd., buyers should request the latest UL and UL DLC test reports for the 4 ft tube models, as well as CE and RoHS declarations for the bulbs. Verify the lumen output, efficacy (lm/W), CRI, and operating temperature range against the specifications provided in the product data sheet. Sampling is advisable for the sensor‑integrated tube to confirm response time and detection range before placing a bulk order.

Typical minimum order quantities for Chinese LED tube manufacturers range from 500 to 1,000 units per model, with lead times of 30‑45 days after receipt of a purchase order and approved samples. Buyers should confirm packaging details - such as double‑wall cartons, anti‑static liners, and moisture‑proof sealing - to protect the LEDs during ocean freight. Requesting a pre‑shipment inspection (PSI) by an accredited third‑party agency can further validate compliance with UL/DLC standards and reduce the risk of non‑conformity at the destination port.

What wattages are available for the 4 ft LED tubes?

The supplier lists 16 W and 18 W options for the four‑foot LED tubes. Both wattages are typical for T8‑type tubes used in commercial retrofits and deliver efficacy around 100 lm/W.

Are the LED tubes UL certified?

Yes, three tube models are described as UL certified, and one model carries UL DLC approval. Buyers should ask for the current UL test report to verify the certification status.

What base types are offered for the golf‑ball LED bulbs?

The catalogue includes bulbs with E26, E27, and B22 bases. The 12 W bulb and the 3 W bulb are both available in these three standard socket formats.

Is a microwave sensor version available?

A 4 ft tube with an integrated microwave sensor is listed. This variant typically provides motion‑activated lighting and is suited for occupancy‑controlled spaces such as conference rooms or restrooms.

What documentation should be requested before ordering?

Buyers should request UL or UL DLC certificates, CE and RoHS declarations, a product data sheet with lumen, efficacy, and CRI values, and a third‑party test report for any safety or performance claims.

What are the typical packaging and shipping methods?

LED tubes are usually packed in cardboard cartons of 20 pcs, while bulbs are placed in poly‑bag packs. Shipments are consolidated in 20‑ft or 40‑ft containers, commonly under FOB Shanghai or CIF destination ports.

What are the standard lead times and MOQ?

For new orders, lead times are typically 30‑45 days after order confirmation and sample approval. Minimum order quantities generally start at 500 units per tube model, though exact MOQ should be confirmed with the supplier.

Which markets commonly import these LED products?

European Union countries, the United States, Canada, and Middle Eastern nations are major importers of Chinese LED tubes and bulbs, driven by energy‑efficiency regulations and demand for retrofit lighting solutions.
