Engineered to excel in architectural, municipal, and commercial outdoor environments with certified waterproof integrity.
Founded on a commitment to clean energy and structural endurance, Ningbo Jianheng Import And Export Co., Ltd. (operating with its core production asset Ningbo Yuancheng Plastic Co., Ltd.) stands as a benchmark manufacturer in the global solar garden light market. With a historical foundation spanning two decades, we specialize in addressing B2B purchasing constraints regarding waterproof lifespans, photothermal efficiency conversion, and casing degradation.
Our operation encompasses a modernized manufacturing facility covering 10,750 square meters, staffed by 105 highly specialized technicians on the production line and supported by 15 dedicated account executives. This infrastructure guarantees rapid communication, robust manufacturing tracking, and frictionless dispatch of wholesale, OEM, and ODM consignments to retailers, project managers, and distributors worldwide.
How our vertically integrated production in Ningbo guarantees cost stability, speed, and strict tolerance control.
By leveraging the capabilities of Ningbo Yuancheng Plastic Co., Ltd., we have established complete control over our structural casings. Outdoor lighting fails most frequently not due to electrical degradation, but because of environmental breakdown—UV exposure yellowing polycarbonate lenses, expansion-contraction cracking, or seal failure. Our plastic injection tooling department produces durable ABS, polycarbonate, and acrylic components engineered to resist degradation in demanding climates.
With Ningbo’s status as a premier global logistics hub, our supply chain maintains strategic access to raw materials and shipping routes. Our components, ranging from monocrystalline silicon panels to specialized LED chips, are sourced directly from verified primary suppliers, insulating our customers from unexpected market price spikes and logistics delays.
Addressing the core challenge: balancing aesthetic design with technical endurance in harsh environments.
Transitioning beyond inefficient polycrystalline modules, we utilize high-purity monocrystalline silicon panels. Combined with low-iron tempered glass and PET lamination, they achieve 21-23% photovoltaic conversion, enabling charging even under overcast skies.
Water intrusion is prevented using dual-groove silicone gaskets, ultrasonic plastic welding, and hydrophobic venting membranes. This allows internal pressure equalization without letting moisture bypass our IP65 and IP67 barriers.
We supply high-capacity Lithium Iron Phosphate (LiFePO4) and specialized Ni-MH cells equipped with overcharge and over-discharge protection circuits. This design ensures reliable operation across a temperature range of -20°C to 60°C.
We are shifting from static lighting structures to responsive, integrated nodes. Our R&D team is currently focusing on three primary technical advancements:
Tailored lighting designs configured for specific regulatory, architectural, and commercial needs.
Public pathways require high durability, low maintenance, and reliable performance. Our buried ground lights (such as the YC-LG010 Aluminum Deck Light) feature corrosion-resistant aluminum housings capable of withstanding pedestrian traffic and heavy lawn maintenance machinery without seal failure.
For distributors and home-improvement retailers, packaging, certification, and ease of assembly are crucial. We provide drop-test certified retail packaging and complete, step-by-step user manuals. This helps minimize return rates and simplifies assembly for the end consumer.
Hotels, resorts, and corporate campuses require consistent color temperatures and premium aesthetics. Our custom flickering flame solar lanterns and glass pendant installations deliver atmospheric lighting without the high installation and utility costs of traditional trenching and wiring.
For residential complexes and industrial zones, safety is a priority. Our high-power LED solar wall lights, equipped with integrated passive infrared (PIR) motion sensors, provide reliable lighting on demand. This conserves battery power while deterring unauthorized entry.
Ensuring your imported shipments meet all destination market customs and safety regulations.
At Ningbo Jianheng, quality control is integrated into every step of our production process rather than being treated as a final check. We conduct tests on all raw materials, including verifying battery capacities and monitoring the degradation of LED chips, before manufacturing begins. Our factory maintains active BSCI (Business Social Compliance Initiative) and ISO9001:2015 certifications, ensuring ethical labor practices and consistent quality management.
For international markets, compliance is key to avoiding delays at customs. Our products carry verified CE, RoHS, UKCA, and WEEE marks, allowing for direct sale in the European Union, United Kingdom, North America, and Asia-Pacific regions.
Additionally, we conduct aging tests on all products. Every light undergoes a continuous 24-hour cycle test in simulated wet conditions to ensure waterproof seals remain intact before packing.

Frequently asked questions from procurement officers, global distributors, and engineering contractors.
For standard custom packaging or logo printing, our starting MOQ is typically 200 units per model (e.g., model YC-CP023). For complete custom molding projects developed from CAD files, MOQ requirements vary based on the part's size and complexity. Please contact us to discuss your design details.
We test our products in our in-house lab using rain spray simulation chambers and water immersion tanks. Every batch undergoes sample testing where lights are operated under water pressure to verify that seals, gaskets, and ultrasonic joints prevent leakage before packaging.
We support a 7-day rapid prototyping service. Once we receive your CAD drawings or design parameters, our engineering department creates 3D-printed structural components and matches them with the appropriate solar circuit boards. This allows us to deliver functional physical samples quickly.
For regions experiencing freezing temperatures, we recommend Ni-MH or low-temperature LiFePO4 cells. We also adjust our battery management system (BMS) configurations to limit charging rates during extreme cold, helping protect the cells and extend their operational lifespan.
Yes, all outdoor-facing plastic components (such as ABS, PC, and PMMA) are formulated with UV-stabilizing additives. This helps prevent yellowing, chalking, and brittleness caused by prolonged exposure to sunlight.
We offer a standard 1-year product warranty. For civic, architectural, and municipal projects, we can provide extended warranties by incorporating premium components, such as upgraded monocrystalline panels, branded LED chips, and high-cycle batteries.
