Explore our highly specialized lighting components, designed to deliver exceptional reliability and efficiency across commercial, medical, and specialized industrial sectors.
Safety, regulatory enforcement, and energy conservation drive the modern transformation of heavy-industry lighting networks.
In hazardous environments—where flammable gases, combustible dusts, or ignitable fibers are present—standard industrial lighting is a catastrophic liability. A single electric arc or thermal anomaly can result in devastating explosions. Consequently, Hazardous Location (HazLoc) lighting is subject to the world’s most stringent technical guidelines, governed by regional and international certification systems including ATEX (Europe), NEC/CEC (North America), and IECEx (Global).
Modern petrochemical plants, offshore drilling rigs, chemical warehouses, and agricultural processing centers are facing escalating pressure to transition from legacy High-Intensity Discharge (HID) and fluorescent lamps to solid-state LED systems. The transition is not simply driven by energy-efficiency mandates; it is fundamentally about structural integrity, thermal management, and lowering the Total Cost of Ownership (TCO) in environments where maintenance activities require severe safety shutdowns and highly specialized technician labor.
Furthermore, standard light fixtures fail under extreme operational parameters. True hazardous location engineering requires robust copper-free aluminum housings, explosion-proof tempered glass lenses, and customized heat sinks designed to control surface temperatures (T-ratings) effectively. As a leading manufacturer, we combine our profound semiconductor packaging heritage with precision manufacturing to deliver fixtures that function flawlessly in Class I Division 1, Class I Division 2, and ATEX Zone 1/21 ecosystems.

From raw ingot processing and die-casting to SMD placement, driver encapsulation, and explosive gas chamber simulation testing, we optimize for speed, quality, and structural integrity.
Operating under the rigorous standard of "High Quality, Zero Defect", every production batch is put through rigorous tests including high-pressure nitrogen gas leak tests, salt-spray corrosion analysis, thermal shock chambers, and vibration resistance tables to ensure survival in offshore environments.
By choosing to partner with a specialized supplier like Ningbo Gravity Light Manufacturing Co., Ltd., global industrial procurement teams bypass intermediaries. You receive products manufactured to precise compliance protocols (RoHS, CE, ETL, KC, PSE, and customized domestic standards) with complete design flexibility, such as specialized bi-color configurations, integrated smart sensors, emergency battery back-ups, and varying optics for challenging structural installations.
Understanding regional directives and how our lighting engineering meets or exceeds international safety requirements.
| Classification System | Target Environment Type | Hazard Characteristics | Gravity Light Compliance Standard |
|---|---|---|---|
| Class I, Division 1 (North America) | Flammable Gases / Vapors | Ignitable concentrations exist under normal operating conditions continuously or periodically. | Flameproof housing, heavy-duty tempered glass, silicone gaskets, tested to Ex d standards. |
| Class I, Division 2 (North America) | Flammable Gases / Vapors | Ignitable concentrations are only present under abnormal failure conditions. | Hermetically sealed components, non-sparking design configurations, optimized thermal path. |
| Class II, Division 1 & 2 | Combustible Dusts | Presence of magnesium, coal, aluminum, or grain dusts capable of causing ignition. | Dust-tight IP66/IP67 enclosure ratings, smooth external geometry to prevent heat-trapping dust buildup. |
| ATEX / IECEx Zone 1 & 2 | Gases, Vapors, & Mists | High likelihood of explosive atmospheres in daily operation (Zone 1) or low likelihood (Zone 2). | Intrinsically Safe (Ex i), Flameproof (Ex d), and Increased Safety (Ex e) structural options. |
From marine rigs to automated paint booths, we supply tailored systems engineered for reliable long-term operations.
Upstream offshore drilling platforms and downstream petrochemical refinery lines operate around explosive vapors like methane, butane, and hydrogen. Our fixtures are designed with spark-resistant, impact-resistant housings that withstand continuous structural vibration and marine salt spray.
Aggressive organic vapors and acid mists will quickly degrade standard metallic parts. Our customized polyester powder coatings and specialized polymer components provide corrosion protection while maintaining superior luminous flux and color rendering indexes (CRI).
Organic dusts (flour, starch, wood dust, agricultural residues) can build up on fixtures, creating a thermal barrier. If the temperature exceeds safe limits, a dust explosion can occur. Our fixtures feature a sloped, dust-shedding profile and thermal limiters to ensure safe surface temperatures at all times.
Humid environments filled with methane and corrosive hydrogen sulfide require robust, chemically resistant, IP66-rated explosion-proof luminaires to ensure continuous and safe municipal operations.

Expert technical insights to help you make informed procurement decisions for hazardous locations.
Under the NEC/CEC system, Class I, Division 1 locations are environments where ignitable concentrations of flammable gases, vapors, or liquids are present continuously, intermittently, or during routine maintenance. Class I, Division 2 locations are environments where these hazards are only present during accidental system failures or unusual conditions. Division 1 fixtures require robust flameproof (Ex d) construction, whereas Division 2 fixtures can use non-sparking configurations (Ex n or Ex e) depending on the surface temperature requirements.
Explosion-proof light fixtures do not keep explosive gas out of the housing; rather, they prevent an internal ignition or spark from escaping into the surrounding hazardous atmosphere. If gas leaks inside and is ignited by the electronics, the heavy-duty enclosure contains the explosion and cools the escaping hot gases before they can ignite the external environment.
The Temperature Rating (T-Rating) specifies the maximum surface temperature that a fixture will reach during operation. The T-rating must be lower than the auto-ignition temperature of the gases or dusts present in the installation area. T-ratings range from T1 (450°C) to T6 (85°C). We optimize thermal dissipation in our LED fixtures to maintain safe, low T-ratings.
Absolutely not. Standard industrial LED lights lack hermetic seals, fail to limit maximum surface temperatures under fault conditions, and do not feature spark-free drivers. Using uncertified fixtures in hazardous locations violates safety codes and poses severe explosion risks.
We recommend fixtures with an IP66 or IP67 rating. IP66 protects against high-pressure water jets from any direction, which is ideal for washdowns. IP67 protects against immersion in water up to 1 meter for 30 minutes, making it suitable for heavy marine use.
Chip-on-Board (COB) technology mounts multiple LED dies directly to a substrate, creating a single lighting module. This structure improves thermal transfer, eliminates mechanical solder joints that can fail from vibration, and allows for compact, high-efficiency fixtures with uniform light distribution.
Copper-free aluminum alloy with an electrostatically applied polyester powder-coating is the industry standard. This combination prevents galvanic corrosion from salt spray and stands up to acidic or alkaline environments commonly found in chemical plants.
Yes. Our designs are engineered to meet international safety standards and carry certifications such as RoHS, CE, and ETL, enabling seamless integration across global industrial markets.
We operate under a "High Quality, Zero Defect" standard. Every production batch undergoes automated optical inspection (AOI), high-voltage isolation tests, thermal runaway monitoring, and pressurized nitrogen leakage tests before shipping.
Yes. We provide tailored lighting solutions, supporting custom bracket designs, specialized optics, emergency battery backups, and wide-input voltages (e.g., 100-277VAC or 347-480VAC) to meet various site requirements.
