The global industrial landscape is undergoing a radical transition. As logistics hubs, automated fulfillment centers, and high-precision manufacturing plants scale up worldwide, the demand for highly efficient overhead illumination is soaring. According to recent industrial energy audits, high ceiling spaces—defined as overhead mounting heights above 6 meters (20 feet)—consume up to 40% of a facility’s total electrical budget solely through illumination.
The global shift from outdated High-Intensity Discharge (HID) and Metal Halide (MH) lamps to advanced solid-state LED systems is no longer just a trend: it is a financial and operational imperative. Modern warehouse operators demand solutions that not only slash power draws but also improve safety metrics (e.g., higher color definition for barcode scanners) and integrate seamlessly with smart Building Management Systems (BMS). As a result, the market requires customized LED High Bay lights designed to handle thermal extremes, voltage fluctuations, and hazardous particulates.
Industrial installations are frequently subject to extreme humidity, chemical vapors, and high particulate levels. Advanced high bay systems leverage IP65/IP66 and NEMA ratings to guarantee long-term ingress protection.
By transitioning from legacy HID lamps (yielding ~60-80 lm/W) to state-of-the-art custom LED configurations achieving up to 190 lm/W, facilities reduce operational expenditures by 60% or more, resulting in rapid payback periods.
Modern high-bay platforms support wireless interfaces, including DALI, Zigbee, and Bluetooth Mesh networks, enabling localized dimming, daylight harvesting, and automated motion-activated sensing profiles.

Our manufacturing process follows strict quality control standards at every stage—from material selection to final inspection—ensuring reliability and long-term performance. In-house SMT processing, reflow soldering, and visual inspection processes minimize assembly failure rates below 0.1%.
We provide flexible OEM and ODM services to meet the diverse needs of global clients. By working closely with distributors, project contractors, and brand owners, we develop tailored lighting solutions that align with different market requirements and application scenarios. From customized mounting brackets to bespoke driver housing and custom beam angles, our R&D team streamlines development cycles from CAD design to sample approval in under two weeks.
At Dorde Lights, we believe long-term success comes from trust and consistency. We are committed to maintaining close cooperation with our partners and continuously improving our products and services to adapt to evolving market demands. Every production batch undergoes comprehensive aging tests and lighting assessments to verify consistency of color temperature (CCT) and luminous output.
Our vision is to become a trusted global LED lighting manufacturer recognized for quality, innovation, and customer-focused solutions. We will continue to invest in product development and manufacturing excellence to bring better lighting experiences to users around the world.
Engineering high bay luminaires for high reliability requires careful consideration of three critical physics domains: thermodynamics, electrical topology, and optical propagation. The performance and degradation profile of an LED array depends directly on junction temperature management. Below, we break down our core manufacturing paradigms that differentiate our industrial lights from standard consumer fixtures.
Our custom fixtures leverage heavy die-cast ADC12 aluminum housings with optimized convective fin structures. This ensures that the thermal dissipation path keeps the junction temperature of the LED chips below 75°C, preserving lumen maintenance over an 80,000-hour L70 lifespan.
We source only premium MeanWell, Sosen, and Inventronics drivers configured for Power Factor (PF) >0.97 and Total Harmonic Distortion (THD) <10%. Integrated 4kV-10kV surge protection shields circuits from grid voltage spikes and industrial inductive switching noise.
Every space has unique geometry. We utilize highly polished, UV-stabilized polycarbonate lenses with tight optical distributions (60°, 90°, 120°, and asymmetric patterns) to focus light directly onto workspaces and reduce glare (UGR < 22).
| Performance Parameter | Legacy Metal Halide (400W) | Standard LED High Bay | Dorde OEM Premium High Bay |
|---|---|---|---|
| System Luminous Efficacy | 50 - 70 lm/W | 120 - 140 lm/W | 160 - 190 lm/W |
| Lumen Depreciation (L70) | 15,000 Hours | 50,000 Hours | 80,000+ Hours |
| Power Factor (PF) / THD | 0.85 / >25% | 0.90 / <15% | 0.97 / <10% |
| Color Rendering Index (CRI) | Ra 65 | Ra 70 - 80 | Ra 80 - 95 (Bespoke) |
| IP / IK Impact Rating | IP20 / IK05 | IP65 / IK08 | IP66 & IP69K / IK10 |
Our research and development pipeline focuses on three key emerging trends:
One size does not fit all. Different industrial and commercial contexts demand distinct physical configurations, lumen densities, and safety certifications.
High vertical racking requires precise photometric footprints to ensure light reaches bottom tiers without causing upper-level glare. Our Solution: Narrow-beam linear high bays (typically 30° x 70° optics) that deliver uniform lighting down narrow aisles while minimizing glare for automated forklifts and human operators.
Stamping mills and steel processing plants subject luminaires to elevated ambient temperatures (exceeding 50°C), heavy particulate dust, and vibrations from machinery. Our Solution: IP66-rated cast aluminum UFO high bays with decoupled drivers. The thermal break separates driver heat from the LED array, preventing early component failure.
Hygiene requirements require high-pressure washdowns with harsh cleaning solutions, and fixtures must be free of glass or exposed fasteners that could contaminate production lines. Our Solution: NSF-certified, seamless, corrosion-resistant outer shells with high-strength impact-resistant PMMA lens matrices that support IP69K high-pressure thermal washdowns.
The manufacturing ecosystem of the Pearl River Delta in Guangdong, China, offers unmatched production efficiencies. As a vertically integrated manufacturer based in this cluster, Dorde Lights leverages this proximity to provide significant cost, quality, and delivery advantages to our global clients:
Exporting industrial light fixtures to diverse markets requires strict adherence to international electrical, safety, and environmental standards. Dorde Lights ensures all products are engineered and tested to satisfy global regulatory benchmarks, streamlining customs clearance and local installation approvals.
Luminaires destined for the US and Canada are engineered to meet UL 1598 (Luminaires) safety standards and are listed with ETL or UL. Additionally, we qualify products for DLC (DesignLights Consortium) Premium status, unlocking energy rebates for commercial operators.
All European configurations carry full CE, RoHS, and GS markings. We ensure compliance with the Ecodesign Directive (ErP) and electromagnetic compatibility limits (EN 55015), ensuring zero interference with existing local network nodes.
For Oceania and East Asian markets, we supply SAA and C-Tick certified drivers alongside KC and PSE approved chassis configurations, matching local grid characteristics and nominal operating voltages.
Bespoke Logistics & Project Support: Beyond production, we offer comprehensive project assistance. We generate Dialux lighting simulations to calculate exactly how many high bay lights, what beam angles, and what spacings are required to achieve target Lux/Fc levels. We also manage shipping logistics (FOB, CIF, DDP) to simplify the delivery process.
