Ningbo Jianheng Import And Export Co., Ltd. (operating alongside Ningbo Yuancheng Plastic Co., Ltd.) stands at the forefront of China's clean energy lighting landscape. Over a rich 20-year history of technological evolution, we have grown from a local assembly workshop into a globally respected, fully integrated manufacturer and supplier. We specialize in high-efficiency solar pathway, deck, garden, and structural lighting systems.
Spanning an industrial footprint of 10,750 square meters in Ningbo, our facility is engineered for high-throughput production, advanced material testing, and agile prototyping. With a workforce of 105 highly skilled assembly and tooling technicians, paired with 15 specialized office and engineering staff, we maintain a reliable ecosystem that controls every stage of manufacturing—from raw plastic extrusion and circuit design to container loading.
As the demand for energy-efficient, smart home-compatible landscape illumination rises, color-changing solar garden lights have transitioned from simple garden accents into complex, highly integrated outdoor fixtures. Our product design strategy targets critical engineering areas:
We deploy premium monocrystalline silicon solar cells with conversion efficiencies up to 22.5%. Monocrystalline technology outperforms standard polycrystalline configurations under diffused and low-light conditions, ensuring that color-changing systems receive sufficient charge even in autumn and winter seasons.
Traditional Ni-MH batteries (such as 1.2V 600mAh cells) are increasingly being upgraded to high-performance LiFePO4 (Lithium Iron Phosphate) or high-capacity Li-ion (e.g., 2200mAh 18650) batteries. These chemistries extend cycle life to over 2,000 cycles, and we integrate dedicated Battery Management Systems (BMS) to protect against overcharging, over-discharging, and low-temperature degradation.
Our color-changing light engines utilize high-brightness surface-mount LEDs (SMD 5050 RGBW). The inclusion of a dedicated 'W' (White) chip ensures high-quality warm white (2700K-3000K) utility lighting, while the RGB chips provide vibrant decorative transitions. Advanced microcontrollers (MCUs) drive custom smooth fading, flickering flame, and chasing effects.
Outdoor fixtures face intense UV exposure, temperature fluctuations, and moisture. We utilize UV-stabilized polycarbonate (PC), marine-grade aluminum, and anti-rust stainless steel finishes. Double-ring silicone gaskets and potting sealants secure our electronics to IP65 and IP67 standards.
The next generation of our solar garden lights integrates Smart Bluetooth Mesh and Zigbee controllers. These systems allow municipal buyers and smart-home consumers to control thousands of lights simultaneously via mobile application or central smart-home hubs (compatible with Matter protocols). Adaptive dimming curves adjust light output dynamically based on remaining battery capacity, ensuring uninterrupted illumination even during long stretches of rainy weather.
Ningbo Jianheng provides optimized supply chain services designed for diverse commercial procurement channels:
We provide drop-test approved mail-order packaging, barcode labeling, custom pack sizing (e.g., 4-pack, 6-pack, 10-pack), and compliance documents directly suited for rapid logistics fulfillment.
Our factory supports high-volume manufacturing runs, custom color boxes, palletization, and strict adherence to retail compliance audits, including environmental and social standards.
For custom commercial and municipal bids, we offer specialized photometric data (.IES files), custom structural mounts, and high-lumen, architectural-grade solar fixtures designed to match complex spatial plans.
At Ningbo Yuancheng Plastic Co., Ltd. and Ningbo Jianheng, quality control is integrated into every phase of production. We recognize that international markets enforce strict reliability and safety criteria, which is why our plant has successfully obtained BSCI (Business Social Compliance Initiative) and ISO9001:2015 quality management certifications.
Our product families are certified to meet international regulatory standards, carrying CE, RoHS, and UKCA marks. For the North American market, we offer configurations compatible with FCC Part 15 and UL/ETL specifications. We also utilize in-house optical testing chambers (integrating spheres), salt-spray corrosion cabinets, and waterproof test rooms to guarantee structural performance over years of outdoor use.
Operating out of the Yangtze River Delta industrial hub—specifically in Ningbo, Zhejiang province—grants us access to the world's most dense electronics, polymer, and shipping networks. This geological advantage ensures resilient production and logistics pipelines:
Unlike assembly-only companies, we utilize our sister company Yuancheng Plastic Co., Ltd. for direct injection molding. We maintain direct relationships with chemical suppliers for UV-treated ABS, PC, and PMMA plastics, which insulates us from seasonal polymer market volatility.
We deploy high-speed Pick-and-Place SMT machines to assemble solar controller PCBs. Automated optical inspection (AOI) detects component misalignment, cold solder joints, or voltage anomalies before the boards transition to the final assembly line.
Our factory is located less than 50 kilometers from Ningbo-Zhoushan Port—the world's busiest container port by throughput. This proximity minimizes drayage costs, shortens shipping lead times, and allows us to quickly navigate high-volume export procedures.
We support a broad range of custom lighting projects, specialized specifications, and wholesale programs. Our engineering and design teams work in lockstep with procurement officers to realize complex product designs:
