Linear Lights
Source high-quality linear lights directly from vetted manufacturers and wholesale suppliers in China. Designed for commercial lighting distributors, importers, and brands seeking OEM/ODM production, our catalog connects you with reliable factories capable of handling bulk orders and custom specifications.
Commercial linear lighting demands precise thermal management, uniform light distribution, and rigorous electrical reliability. When importing these fixtures in volume, the primary sourcing challenge is separating basic assemblers who rely on generic off-the-shelf components from true manufacturers who tightly control the aluminum extrusion, PCBA (Printed Circuit Board Assembly), and driver integration.
Specifying Commercial Linear Lights for Production
To ensure consistency across large installations, your RFQ must lock down critical performance metrics. Vague specifications often lead to unauthorized component swapping on the factory floor to increase margins.
Essential RFQ Parameters
- Luminous Efficacy: Specify minimum lm/W (e.g., over 130 lm/W for high-efficiency commercial spaces).
- Glare Control (UGR): For office environments, mandate a UGR of under 19, requiring micro-prismatic diffusers.
- Color Consistency: Specify MacAdam ellipses (SDCM under 3) to prevent color shifting across continuous runs.
- Dimming Protocols: Clearly state compatibility requirements (DALI, 0-10V, Triac, or Zigbee).
- Housing Material: Specify 6063-T5 aluminum with a minimum wall thickness to ensure structural rigidity and heat dissipation.

Talk to our teamManufacturing Variables and Quality Control
The longevity and aesthetic quality of a linear light are determined by a few critical manufacturing variables. The weight and quality of the aluminum housing directly impact the lifespan of the LED chips by acting as the primary heat sink.
| Component | Standard Commercial | Premium Specification |
|---|---|---|
| Housing Thickness | 1.0mm - 1.2mm | 1.5mm - 2.0mm+ (No sagging over long spans) |
| Diffuser Material | Extruded PC (Polycarbonate) | PMMA (Acrylic) - High UV resistance, no yellowing |
| LED Chip Density | Standard pitch (visible hotspots) | High density or COB (flawless dot-free illumination) |
| Driver Integration | External or standard internal | Flicker-free, isolated premium driver (e.g., Osram/Tridonic) |
Catching thermal or electrical issues late in production is costly. Implementing rigorous Quality Control & Inspection during the SMT phase and ensuring a mandatory 24-hour aging test is non-negotiable. Furthermore, before committing to a supplier for complex continuous-run systems, conducting thorough Factory Audits helps verify if they actually own the extrusion molds and SMT lines, or if they are simply outsourcing the core components.
Customization and OEM Capabilities
For brands developing proprietary lighting systems, utilizing professional OEM/ODM Services allows for custom aluminum profiles, tailored optics (such as asymmetric wall washers or batwing distributions), and specialized joinery.
Continuous Run Lighting
For seamless continuous runs, specify overlapping diffusers or specialized light-leak blockers at the mechanical joints. Light leaks at connection points (L, T, X connectors) are the most common aesthetic defect in poorly engineered linear systems.
Pricing Drivers, MOQs, and Lead Times
Wholesale pricing for linear lighting is highly variable, driven primarily by the aluminum weight (market commodity prices), the brand of the LED driver, and the complexity of the optical diffuser.
Compare pricing models, tooling costs, and factory capabilities for your specific linear lighting requirements.
