Explore our diverse portfolio of smart off-grid power, phototherapy systems, extreme weather safety equipment, and structural architectural lighting solutions engineered to global standards.
In harsh industrial infrastructures—such as chemical refineries, offshore drilling rigs, wastewater treatment plants, and coastal processing zones—lighting fixtures are subjected to continuous chemical and environmental stress. Choosing standard luminaire systems in these spaces results in rapid oxidation, enclosure failures, short circuits, and significant safety hazards. Standard "weatherproof" configurations are structurally incapable of surviving environments characterized by high salinity, acidic vapors, volatile solvents, or alkaline dust.
This technical whitepaper outlines the advanced structural design, materials science, and deployment strategies necessary to achieve long-term reliable illumination. We examine the critical design guidelines, regulatory compliance standards, global supply chain parameters, and custom OEM/ODM capabilities needed by procurement directors and lead project engineers to specify the correct anti-corrosion luminaires.
How our customized engineering solves the fundamental physical mechanisms of environmental degradation.
Enclosures designed and coated to withstand long-term exposure to marine environments, high humidity, and aggressive offshore atmospheres in compliance with ISO 12944 classification.
Utilizing our patented System-level Integrated Lighting Module to separate the heat-generating semiconductor driver from the LED chip matrix, eliminating premature thermal degradation.
Precision-engineered continuous silicone or fluorosilicone gaskets prevent ingress of pressurized water jets, cleaning agents, hot steam, and corrosive atmospheric pollutants.
Ningbo Gravity Light Manufacturing Co., Ltd. was awarded the China National High-Tech Enterprise certification in 2021. With over 20 years of expertise in high-performance packaging and semiconductor innovation, we specialize in high-end COB technology, custom PCB design, and robust industrial lighting solutions.
Our goal is to be a globally recognized leader in premium light sources. Our services go far beyond standard assembly—we partner with global engineering and procurement firms to design, manufacture, and certify customized OEM/ODM industrial light fixtures capable of operating in the world's most aggressive environments.
Driven by our core corporate philosophy of "High Quality, Zero Defect", we enforce stringent quality controls at every stage, from material incoming inspection (IQC) to automated optical inspections (AOI) and final burn-in testing.
A standard catalog fixture rarely solves the complexities of extreme industrial sites. Specific environmental chemistry, physical mounting configurations, and safety standard zones differ from project to project. Our engineering division offers comprehensive design flexibility:
Depending on the corrosion profile of your project site, we offer tailor-made structural materials:
Integrating our 20+ years of semiconductor expertise, our custom-designed PCB boards minimize thermal resistance between the junction of the LED and the outer casing. By applying our patented System-level Integrated Lighting Module, we reduce total system operating temperatures by up to 15°C compared to conventional systems. This increases the lifetime of critical electrical components (especially internal capacitors) and ensures the luminaire delivers high lumen output without thermal runaway.
We source and integrate high-end programmable drivers (Meanwell, Inventronics, or custom-designed Gravity Light drivers) equipped with robust surge protection (up to 10kV/20kV line-to-earth) to mitigate unstable power grids. Dimming protocols include 0-10V, DALI-2, Zigbee, and customized IoT configurations for smart industrial automation networks.
How Gravity Light bridges the gap between premium Chinese manufacturing and localized global operations.
We provide complete certification support (RoHS, CE, ETL, KC, PSE). We supply accredited laboratory test reports (IP ratings, IK impact ratings, LM-79, LM-80, and salt spray certificates) for local inspection authorities.
Located in Ningbo, the global epicentre of advanced tooling, casting, and electronic manufacturing. We leverage vertical integration to offer fast prototyping, optimized component sourcing, and efficient maritime shipping.
Our engineering team collaborates directly with your design office, offering custom dialux simulation studies, photometrical analyses, and site integration reviews to prevent field installation errors.
Understanding the exact localized stresses of each application ensures long-term operational success. We customize our anti-corrosion luminaires according to the following target sectors:
Exposed to extreme environmental factors including constant salt-spray, high UV exposure, and heavy mechanical impacts from ocean waves. The atmospheric chemistry consists of continuous chlorine ions. Here, we utilize copper-free aluminum alloy housings with an ultra-thick baked-on powder coating or structural 316L stainless steel components, achieving full protection against galvanic and chemical corrosion.
In addition to requiring explosion-proof certifications (ATEX/IECEx Zones 1 & 2), these locations are prone to severe chemical attack from corrosive gases such as sulfur dioxide (SO2) and hydrogen sulfide (H2S). We design hermetically sealed luminaires using non-reactive tempered safety glass lenses and chemical-resistant polymer gaskets (Fluorosilicone) to seal out dangerous ambient gases.
Wastewater structures produce high levels of hydrogen sulfide, which reacts with oxygen to form sulfuric acid on damp metal surfaces. Standard iron and low-grade aluminum fixtures degrade rapidly. In these projects, we recommend our specialized non-metallic GRP (Glass Reinforced Polyester) linear fixtures, providing complete chemical immunity and ensuring the physical integrity of the lighting layout.
These plants undergo daily high-pressure sanitation procedures using aggressive chlorinated foam, caustic soda, or nitric acid-based detergents. Luminaires must be certified to **IP69K** to withstand water temperatures up to 80°C and pressures of 100 bar, while maintaining a smooth, non-porous structure to prevent bacterial accumulation.
The future of heavy-industrial lighting technology over the next decade.
Global corporations require sustainable manufacturing processes. We design our industrial fixtures for circularity—allowing easy driver replacements and modular LED board upgrades, minimizing electronic waste.
Modern heavy industry requires smart luminaires that monitor their own thermal profiles and power draw, reporting real-time component health metrics to prevent unscheduled shutdowns.
Modern optics focus on precise light distribution to minimize glare, increase worker safety, and maximize target lux levels while reducing the total fixture power footprint.
