Explore our industrial application portfolio designed for high durability and resource efficiency.
Ningbo Gravity Light Manufacturing Co., Ltd. was proudly awarded the China National High-Tech Enterprise certification in 2021, building upon over 20 years of core expertise in semiconductor packaging, optical design, and structural integration. As a leading manufacturer of commercial, industrial, and specialized light engines, we bridge the gap between high-level semiconductor manufacturing and ruggedized warehouse high bay applications.
Our capabilities go beyond standard luminaire assembly. Leveraging our proprietary chip-on-board (COB) technology, custom PCB design, and robust thermodynamic designs, we manufacture high bay structures that maintain stable lumen output under the most grueling warehouse environment configurations.
How Modern Smart Warehousing Demands Are Transforming Industrial Optical and Thermal Engineering.
With global net-zero goals, high bay efficacy has shifted from 120 lm/W to over 180 lm/W. By deploying state-of-the-art COB packaging, system designers achieve substantial energy reductions without sacrificing lux density at the working plane.
Modern warehouse operations demand adaptive lighting. High bay systems are no longer static loads; they integrate DALI-2, Zigbee, and sensor systems to adjust intensity based on real-time pedestrian presence and daylight harvesting.
Worker comfort impacts operational productivity. Advanced optical lenses are designed to restrict UGR to <19, preventing visual fatigue for forklift operators maneuvering under high vertical storage racks.
The convergence of logistics automation and sustainable design makes the choice of a high bay lighting manufacturer critical. Today's systems must maintain structural stability while interfacing with complex warehouse management networks. As automated storage and retrieval systems (ASRS) grow in ceiling height, lighting solutions must adapt to project light precisely through tight racking aisles, eliminating shadowed zones that present occupational hazards.
B2B procurement specialists, electrical engineers, and project developers face strict parameters when acquiring industrial lighting assets. Sourcing from a verified manufacturer guarantees consistency across global properties. Gravity Light offers structured support built around these strict requirements:
Shipping to international regions requires a clear understanding of regional electrical and safety codes. Sourcing high bay systems without certified compliance can lead to project delays and insurance liability issues.
Our facility ensures all hardware is backed by global compliance assurances, offering complete documentation for markets in The United States, Vietnam, Japan, Britain, Italy, Russia, India, Brazil, Spain, and the Middle East.
Our designs proudly carry: RoHS, CE, and ETL Certifications. Additionally, Ningbo Gravity Light obtained the Utility Model Patent for System-level Integrated Lighting Modules, guaranteeing that our components are engineered to reduce component stress and eliminate field failures.
Different warehouse topologies demand distinct optical configurations. We match structural layouts to custom high bay solutions.
Standard drivers fail at -30°C. Our specialized cold storage high bays utilize drivers with premium low-temperature capacitors and custom heat transfer gaskets to prevent seal degradation from thermal cycling.
Aisles narrower than 2 meters require asymmetrical narrow optics (30°x90° or 60°x90°) to project light directly onto vertical storage levels instead of wasting energy on top shelves.
High ambient temperatures and airborne oil particles degrade optical acrylics. We utilize tempered glass covers and chemical-resistant powder-coated housings to resist ambient stresses.
Our research and development vision is committed to driving long-term value for logistics operations. By centering our innovations on semiconductor precision, we are building tomorrow's infrastructure today:
1. Adaptive Spectrums: Development of high bay lights that alter color temperature throughout shifts, improving human focus during night shifts and encouraging circadian rhythm alignment.
2. Material Circularity: Implementing cradle-to-cradle designs that allow simple, toolless repair of modules and drivers, reducing waste and supporting local compliance with eco-design regulations.
3. Smart Grid Compatibility: Designing power drivers capable of operating on fluctuating microgrids and direct DC grids powered by local solar storage installations.
Our R&D department addresses industrial needs across a broad scope of lighting applications, including:
Commercial Lighting, Indoor Lighting, Outdoor Lighting, Industrial Lighting, Landscape Lighting, Horticultural Lighting, UV Lighting, Emergency Lighting, Specialty Lighting, Traffic Lighting, Intelligent Lighting, Drone Lighting, Health and Medical Lighting.
By taking learnings from demanding sectors like medical, horticultural, and drone lighting, we apply rigorous vibration, thermal, and UV-aging tests to our flagship warehouse high bay designs.

The LED driver is the most critical element for luminaire longevity. High-quality warehouse high bays utilize industrial drivers (such as Mean Well, Inventronics, or Sosen) with 6kV to 10kV surge protection. Because warehouses operate continuously under high electrical loads, low-end drivers are susceptible to voltage spikes. A high-quality driver maintains consistent output and prevents flicker, guaranteeing stable lumens even in harsh industrial grids.
UGR measures the psychological discomfort caused by high luminance in the field of view. In warehouses, forklift operators constantly look upward to locate pallets on high shelves. High bay systems with poor optics produce extreme glare, increasing operator fatigue and the risk of accidents. Specifying fixtures with UGR <19 or using deep-reflector optical designs improves both safety and efficiency.
A generic 120-degree high bay light scatters light across the top zones of warehouse racks, wasting energy and causing glare. For high-ceiling narrow aisles (mounting heights over 10 meters), narrow beam angles like 60 degrees or specialized oval distributions (such as 30x90 degrees) project light straight down to the work plane. This significantly increases floor-level lux while lowering energy consumption.
Importing requires certifications that verify safety and energy efficiency. For North America, ETL or UL listing is essential to satisfy building codes, along with DLC Premium listing for utility rebates. For European markets, CE and RoHS are mandatory. As a certified High-Tech Enterprise, Ningbo Gravity Light ensures all our warehouse systems meet these global testing standards to avoid regulatory delays.
LED lifespan is directly linked to junction temperature. If the heat generated by the LED chip is not dissipated, the light output degrades quickly. We design our high bays using die-cast aluminum heat sinks with optimized convection paths. This keeps junction temperatures well below the critical threshold, guaranteeing an L80 rating of over 50,000 operating hours.
