Browse our premier engineered line of solar outdoor luminaires. We support advanced customization on electronics, optics, and battery packaging for global projects.
As a pioneer in the global photovoltaic application sector, Ningbo Jianheng Import And Export Co., Ltd. (operating alongside its modern manufacturing arm Ningbo Yuancheng Plastic Co., Ltd.) has anchored itself as a tier-1 solar lighting manufacturer in China. Spanning a history of 20 years of continuous engineering advancement, our group has evolved from a component fabricator into a specialized vertical OEM/ODM giant in commercial outdoor solar lights.
Our core mission revolves around the development, design, and systemic execution of reliable, long-lifecycle, and ultra-high-efficiency solar solutions. Our state-of-the-art facility occupies 10,750 square meters of automated infrastructure. With a dedicated floor-level assembly team of 105 skilled technicians and 15 specialized office and engineering support staff, we coordinate rigorous supply processes to maintain stable output and zero-defect deliveries for global B2B projects, municipalities, and bulk consumer markets.
The 40W solar flood light is widely considered the technical baseline for modern commercial and municipal off-grid lighting installations. Designing an industrial-grade system requires balancing conversion rates, storage lifecycle, thermal degradation, and luminous output. Below is our engineering roadmap outlining the design philosophies that set our OEM configurations apart from standard consumer-grade models.
Standard flood lights rely on low-cost polycrystalline sheets. Our customized 40W series uses high-purity Monocrystalline Silicon cells, boosting conversion efficiency to 21%–23%. The panels feature an anti-reflective, low-iron tempered glass front, ensuring high solar transmission even in low-light environments.
Unlike ternary lithium batteries, we use premium Lithium Iron Phosphate (LiFePO4) storage chemistry. Providing over 2,000 deep-discharge cycles (DoD at 80%) and operating reliably in temperatures ranging from -20°C to +65°C, our batteries feature integrated smart Battery Management Systems (BMS) to protect against overcharging.
Our LED arrays utilize High-Efficacy SMD 3030 / 2835 chips, delivering up to 160 lm/W at the chip level. Optical polycarbonate lenses distribute light across a wide 120-degree beam angle. This design maximizes ground coverage while keeping glare levels low.
| Performance Specification | Standard Market Grade (Entry Level) | Ningbo Jianheng Commercial OEM Grade |
|---|---|---|
| Solar Conversion Efficiency | 15% - 17% (Polysilicon) | ≥ 22.0% (Monocrystalline Silicon) |
| Battery Cycle Life (DoD 80%) | 500 - 800 cycles (Lithium Ternary / Lead-Acid) | ≥ 2,500 cycles (A-Grade LiFePO4 Chemistry) |
| Luminous Efficacy | 90 - 110 lm/W | 150 - 170 lm/W (SMD 3030 Premium Arrays) |
| Smart Power Control | Simple On/Off Timer | Adaptive PWM/MPPT Controllers with Multi-stage PIR Sensing |
| Housing Protection Rating | IP65 (Thin Plastic / Recycled Cast Aluminum) | IP66 / IP67 (Corrosion-resistant Marine Grade Aluminum) |
We manufacture under strict quality standards. Ningbo Yuancheng Plastic Co., Ltd. utilizes Factory 4.0 principles to balance fast turnaround times with consistent manufacturing quality. By integrating our primary raw materials, metal stamping, plastics injection molding, and electronic board positioning inside our 10,750 square meter facility, we maintain full control over the production timeline.
By managing our key component production in-house, we protect partners from supply chain delays. In-house plastics injection molding allows us to custom-engineer optical lenses, gaskets, and outdoor housings. This reduces assembly tolerances and optimizes sealing performance for IP66-rated moisture protection.
Additionally, our proximity to the Ningbo Port provides logistics advantages. From sea freight coordinates to customs documentation, we offer a seamless transition from our production floor directly to international shipping hubs.
Need custom chassis configurations, altered driver outputs, or customized brackets? Our dedicated design division turns specifications into physical, functional engineering samples within a 7-day turnaround window.
Quality is our top priority. We strictly control the raw materials we use and maintain a complete quality inspection process to ensure that our products meet industry standards. Our factory has passed BSCI certification and ISO9001 certification, and our products have CE, ROHS, and UKCA certification. We take pride in being able to provide our customers with quality and reliable solar lights.
We undergo third-party social compliance and workflow audits annually, confirming that all production is completed under safe, ethical, and structured environments.
Every 40W flood light must pass a 100% full-load burn-in test for 24 hours. We test battery cycling, thermal dissipation, and waterproof stability prior to packaging.
Using integrating spheres and goniophotometer equipment, we measure absolute lumen output, Color Rendering Index (CRI), and spatial distribution curves to provide accurate IES files.
Our OEM 40W Solar Flood Lights are designed to meet diverse infrastructural and environmental requirements worldwide. Below are the primary application scenarios where our customizable lighting systems deliver high performance:
Off-grid lighting solutions for public parks, greenways, and pedestrian paths. Integrating high-conversion monocrystalline panels and motion sensors allows municipalities to avoid high trenching and cabling costs. The smart power reduction mode ensures constant illumination even during consecutive rainy days.
Providing continuous nighttime illumination for logistics yards, warehouses, and structural perimeters. Engineered with durable aluminum housings and high-lumen SMD 3030 chips, these systems support security cameras by providing clear lighting throughout the night.
Reliable illumination for rural villages, agricultural facilities, and remote outposts lacking access to the main power grid. The easy-to-install mounting brackets and low-maintenance LiFePO4 batteries provide long-term lighting solutions with minimal upkeep.
High-performance lighting for advertising billboards, parking structures, and corporate entryways. Our customizable optics and color temperature options (from 3000K warm light to 6500K daylight) deliver balanced, high-visibility lighting.
We streamline the procurement process for global importers, distributors, and engineering contractors. From customized casing designs to custom brand packaging, our manufacturing processes are tailored to support efficient supply chain workflows.
We offer comprehensive OEM services, including custom laser engraving, branded packaging, and instructional documentation tailored to your target market.
We adjust battery capacities and LED configurations to meet specific project guidelines, ensuring compliance with local government lumen requirements.
Located near Ningbo Port, we manage shipping logistics, customs documentation, and regional certifications for hassle-free import processes.
