Engineered to upgrade architectural, sports, and municipal infrastructure with advanced LED configurations.
Jiangsu Rhynox Lighting Co., Ltd. (established in 2018) stands at the forefront of industrial and municipal LED modernization. We engineer, manufacture, and export high-performance LED retrofit systems, solar integration devices, and advanced outdoor luminaires. Leveraging over 10 years of deep industry expertise, our engineering teams bridge the gap between legacy infrastructure and intelligent, net-zero municipal ecosystems.
Operating across the core manufacturing hubs of the Yangtze and Pearl River Deltas, we provide global procurement managers, ESCOs, and engineering partners with direct access to highly optimized OEM/ODM channels. By combining military-grade structural design with state-of-the-art optical engineering, we secure verified efficiency and absolute dependability for large-scale urban development projects.
"Our mission is to eliminate the economic and structural friction of transitioning to high-efficiency LED technology. We deliver validated performance upgrades that withstand the harshest environments on earth."
In the domain of commercial, municipal, and industrial lighting, retrofitting has moved past simple module replacement. Modern retrofitting represents a precise mechanical and electronic conversion designed to optimize thermal efficiency, driver reliability, and optical distribution. Below is our engineering roadmap for contemporary LED retrofit systems:
Modern retrofits use custom-molded PMMA and polycarbonate lenses designed for specific beam angles. This minimizes light pollution (Upward Light Output Ratio, ULOR = 0) and directs lumens exactly where needed, reducing waste.
We use programmable constant-current drivers with built-in 10kV/20kV surge protection, a low total harmonic distortion (THD < 10%), and compatibility with smart dimming interfaces (0-10V, DALI-2, and DMX512).
Our structures support NEMA 7-pin and Zhaga Book 18 receptacles. This allows for plug-and-play installation of photocells, motion sensors, and wireless nodes connected to central management systems (CMS).
The industry is moving toward high-efficacy packages exceeding 180 lm/W to 200 lm/W at the system level. By upgrading internal components while preserving the existing outer housing, retrofitting minimizes material waste, reduces capital costs by up to 50% compared to new fixture installations, and significantly shortens project payback periods.
Industrial retrofitting demands customized approaches for different operating environments. A light used in a coastal cargo port faces vastly different stresses than one installed in a sports stadium or a highway tunnel. Jiangsu Rhynox designs and manufactures specialized retrofit configurations for three key sectors:
Coastal installations require high resistance to moisture and salt. Our marine-grade retrofit fixtures feature SUS316 stainless steel hardware, electro-powder coatings, and pass 1000-hour salt spray tests (C5-M corrosion rating) to prevent degradation in humid, high-salinity air.
High-mast stadium retrofits require precise glare control and high color fidelity. We offer specialized optical lenses with a Unified Glare Rating (UGR) < 19, high color rendering (CRI > 80, TLCI > 80), and flicker-free drivers designed for HDTV slow-motion sports broadcasting.
Tunnel lighting requires constant operation and uniform light distribution. Our custom linear LED retrofits provide high visual comfort, prevent the "flicker effect" for drivers, and include automated backup systems for continuous operation.
Jiangsu Rhynox Lighting maintains an integrated production network across the Yangtze and Pearl River Deltas. By leveraging regional electronics, optics, and metal-casting supply chains, we ensure stable material sourcing and competitive pricing for large projects.
Our quality control program goes beyond standard checks. Each unit undergoes a 36-step testing protocol, including thermal shock cycles (-40°C to 85°C), high-humidity exposure, ingress protection verification, and a 72-hour burn-in period. We maintain a 2,000 square meter climate-controlled warehouse to store sensitive electronic components, ensuring optimal assembly conditions and consistent manufacturing quality.
Our quality management system is backed by our digital tracking framework. This traces every single component from the initial SMT placement to final assembly and packaging.
Sourcing commercial lighting equipment globally requires clear risk management and verified certifications. Jiangsu Rhynox operates as a fully insured and audited exporter, offering structured compliance protocols for international buyers:
We provide full lighting simulations before manufacturing begins. This ensures your project complies with localized regulations (such as EN 12464-2 or EN 13201 street lighting standards) and eliminates onsite performance discrepancies.
Every industrial luminaire we build receives a unique digital record containing its exact component batches, SMT reports, spectrophotometer values, and 72-hour burn-in data, enabling full traceability.
To support large-scale commercial retrofits, we back our shipments with global product liability and transit insurance. This protects EPC contractors and distributors throughout the installation lifecycle.
When executing large-scale lighting retrofits, procurement teams must evaluate several technical criteria to ensure long-term performance and high return on investment:
