Built at the Source.
Proven in the Field.
Manufacturing entity: Changzhou Shuangjia Electric Appliance Co., Ltd. · Changzhou, Jiangsu, China
Since 1999, LuyiLighting has focused on industrial and outdoor lighting for environments where reliability cannot be treated as an option. From factory production and optical testing to OEM/ODM development and project support, we bring manufacturing and application thinking into one partnership.
-Who We Are
A factory-backed lighting company built for demanding applications.
Founded in 1999, Changzhou Shuangjia Electric Appliance Co., Ltd. has spent more than two decades developing lighting products for industrial, infrastructure and outdoor applications. Under the LuyiLighting name, we serve overseas customers looking for a manufacturing partner that understands both product engineering and real project conditions.
Our core product families include explosion-proof lights, flood lights, high bay lights, tri-proof lights, street lighting, solar garden lighting and related industrial luminaires. These products are used in environments such as oil and gas facilities, mining operations, power plants, metallurgy, petrochemical sites, warehouses, heavy industrial complexes and large outdoor areas.
What makes our business different is the combination of factory manufacturing, engineering support and project customization. For projects involving special voltage requirements, hazardous areas or unusual environmental conditions, our team can work with buyers on product configuration, lighting selection and OEM/ODM requirements before production begins.
We do not want to be another catalog supplier. We want to be the factory behind lighting products that customers can specify, install and rely on for years.

One clear process.
Six controlled stages.
Every project moves through a defined path — from understanding the application and building the lighting concept to production, inspection and final shipment. Each stage has a clear objective and a clear output.
Inquiry & Requirement Brief
We confirm site type, application, mounting height, operating hours, environmental conditions, target performance and commercial requirements.
Lighting Design & Product Match
We evaluate wattage, optics, CCT, glare, mounting, layout and, when required, DIALux simulation to build a practical lighting concept.
Project Confirmation
Technical details, quantity, voltage, functions, labels, packaging, certifications and OEM / ODM requirements are finalized before production.
Production & Assembly
Materials, LED modules, housings and components move through controlled production, finishing, assembly and aging according to the confirmed order.
Inspection & Verification
Products are checked for appearance, electrical operation, optical output, aging performance and project-specific quality requirements before packing.
Packing & Delivery
Final products are packed, labeled and coordinated for export shipment, with delivery information aligned to the customer's logistics requirements.
A controlled path from raw material to finished luminaire.
Our production sequence is designed to keep product quality visible at every stage — from incoming materials and surface preparation to LED integration, assembly, aging, final inspection and shipment.
Material Incoming Inspection
Initial check of key materials and components before production.
Shot Blasting
Metal surface preparation before finishing and coating.
Polishing
Surface refinement to improve consistency before finishing.
Water Washing
Cleaning and preparation before the protective coating stage.
Powder Coating
Protective external finishing for durability and corrosion resistance.
SMD LED
LED board and module production before fixture integration.
Final Lamp Assembly
Housing, LEDs, optics and electrical components are integrated.
Product Aging Test
Operational run to verify product stability before release.
Final Lamp Inspection
Appearance, electrical and functional checks before packing.
Packing & Shipment
Final protection, labeling, packing and export delivery preparation.
Production in Practice
Real factory images arranged in a balanced 5 × 2 layout: manufacturing and assembly above, testing and delivery below.
Measured performance.
Documented evidence.
Industrial lighting performance should be supported by data, not claims alone. Our optical test capability evaluates beam distribution, luminous intensity and illumination performance, while LED-level reports verify spectral, color and electrical characteristics. Selected real test reports are available below for direct review.

A manufacturing partner for distributors, EPCs and project buyers.
International cooperation requires more than supplying the same fixture to every customer. We support product configuration, private-label requirements, documentation coordination, packaging and export-oriented communication for different markets and industrial applications.
* Certification availability and scope should be confirmed by product model and destination market.
Lighting Distributors
Product portfolios, private-label programs and market-specific configuration support for long-term distribution.
EPC Contractors
Application matching, technical coordination and project-focused product selection for engineering requirements.
OEM / ODM Partners
Product configuration, labeling, packaging and private-label requirements for different markets and customers.
Industrial Project Buyers
Factory-direct communication for demanding industrial, outdoor and hazardous-area lighting applications.
Focused products for
demanding environments.
Our portfolio is focused on industrial, hazardous, outdoor and project lighting where durability, protection, optical performance and maintainability matter. Instead of presenting a generic catalog, we group products by real application needs.
