Discover how precision sheet metal fabrication creates durable industrial lighting housings. Learn about thermal management, LED integration, and weatherproof design for demanding lighting applications.
Introduction
Industrial lighting operates in environments that would quickly destroy consumer light fixtures. Factory floors, warehouses, outdoor areas, and hazardous locations require lighting housings that withstand dust, moisture, vibration, temperature extremes, and chemical exposure. At Fulei Metal, we fabricate lighting housings for industrial lighting manufacturers.
Industrial Lighting Housing Types
High bay lights illuminate large indoor spaces with ceiling heights exceeding 6 meters, requiring housings that dissipate heat from high-power LED arrays. Flood lights provide outdoor area lighting with weatherproof housings (IP65 or higher). Street light housings must withstand decades of outdoor exposure with cobra-head or shoebox profiles. Vapor tight lights are used in environments where water, dust, or chemical exposure is severe, requiring completely sealed housings.
Design Considerations
LED efficiency and lifespan are directly related to operating temperature. We design housings with heat sink fins, thermal interface materials, and strategic aluminum material selection. Industrial lighting housings must prevent dust and water entry through continuous gasket grooves, sealed cable entries, and lens retention systems. Housings must accommodate optical components including lenses, reflectors, and diffusers with precise positioning. Industrial environments subject lighting to vibration and potential impact, requiring robust construction.
Material Selection
Aluminum is the preferred material for LED lighting housings due to thermal conductivity, corrosion resistance, and light weight, fabricated from 5052 and 6061 alloys with anodizing. For corrosive environments, stainless steel lighting housings provide superior corrosion resistance. For indoor industrial lighting, cold-rolled steel provides a cost-effective housing material.
Fabrication Process
Our TRUMPF fiber laser cuts housing components with cutouts for LED mounting, cable entries, and ventilation. CNC press brake machines form housing bodies, heat sink fins, and mounting brackets, with aluminum’s formability allowing complex fin geometries. Sealed housings require continuous TIG welds. Aluminum housings are typically anodized, steel housings are powder-coated, and stainless steel housings may be electropolished.
Case Study: Industrial Lighting Housings for a Norwegian Customer
Industrial lighting housings were produced at Fulei Metal in 2025 for an industrial customer based in Norway, part of a run of close to 1,000 pieces that included stainless mounting hardware. A lighting housing is a shape problem more than a strength problem: the housing has to throw light where it is wanted, keep water out of the gear compartment, and stay put on a structure that vibrates. The three requirements meet at the mounting detail. A housing that is rigidly bolted to a vibrating structure will eventually crack at the fixing, so the mounting points are designed to spread the load into the housing rather than concentrate it at a bolt hole, and fixing positions are checked on the assembled housing rather than on the loose parts, because an aperture that is out of position by a millimetre becomes a visible misalignment once the unit is bolted up.
Conclusion
Industrial lighting housing fabrication requires expertise in thermal management, environmental sealing, and precision manufacturing. Fulei Metal’s comprehensive capabilities make us a trusted partner for lighting housing projects.
