从China供应商批量进口5050 4leds Injection Module

The 5050 4leds injection module from T-sun Opto-Electronic Technology Co., Ltd. is a constant-voltage LED unit built around four 5050 SMD LEDs per module, driven at DC 12 V with a per-module power draw of 0.9 W. Each module measures 36 x 36 x 5 mm and carries an IP65 ingress protection rating, suitable for damp and dusty exterior environments. The supplier specifies a working temperature range of -20 degrees C to +60 degrees C and a storage range of -40 degrees C to +80 degrees C, with a rated lifespan of 50 000 hours. Connection is limited to 20 modules in series for typical installations, and the housing uses milky white ABS cover material.

The module employs ABS plastic housing with a milky white diffuser cover, a standard choice for injection-moulded LED modules in channel-letter and signage applications where uniform light spread and weather resistance matter. The 5050 LED package (5.0 mm x 5.0 mm) is a mid-power SMD format that balances lumen output with thermal management, common in backlighting and shallow-depth sign boxes. The constant-voltage drive architecture at 12 V DC allows direct use with standard switching power supplies but requires attention to total load and voltage-drop across long chains. The IP65 rating indicates protection against dust ingress and low-pressure water jets, though submerged or high-pressure washdown use would need additional sealing.

Typical buyers include sign manufacturers, advertising display fabricators, and retail fixture contractors who need edge-lit or backlit illumination for channel letters, light boxes, and architectural accent lighting. The compact 36 mm footprint suits narrow letter strokes and shallow cabinets where deeper modules would not fit. For import, the standard packing is 100 pieces per bag and 20 bags per carton, with a gross weight of 20 kg and carton dimensions of 50 x 31 x 40 cm. Buyers should confirm with T-sun Opto-Electronic Technology Co., Ltd. the exact LED bin, colour temperature options, and whether UL or CE certification files are available for their market.

T-sun Opto-Electronic Technology Co., Ltd. perceptual address is B Building, Wuwu Technology Park, Longhua Town, Shenzhen 518108, Guangdong, China, placing the supplier in the dense LED manufacturing corridor of Shenzhen. The company's trust tier is listed as harbor, and its response rate shows 0.00 with zero average response hours, meaning no response data is currently recorded. The supplier tier is marked imported, indicating the profile was migrated or aggregated from an external source rather than created natively on the platform.

The listing provides no stated certifications, no verified factory audit details, no declared year of establishment, and no disclosed employee count or production capacity. Buyers should treat the profile as an unverified entry and conduct independent due diligence, including requesting business licence copies, factory inspection reports, and sample evaluation before committing to volume orders. The product description contains concrete electrical and mechanical data, which suggests some level of technical engagement, but the absence of response history means direct communication latency is unknown.
