● Product Description
The LONYUNG LED Linear Light is engineered to deliver seamless, glare-free illumination for the most demanding commercial and architectural environments. Powered by high-efficiency LED chips and a reliable driver system, the fixture produces bright yet soft, uniform light — free from visible LED spotting — for exceptional visual comfort and reduced energy consumption.
Built with a high-grade aluminum housing, the fixture offers efficient heat dissipation and long-term structural durability, ensuring consistent performance and extended lifespan even under continuous daily operation in commercial and professional settings.
Four selectable optics diffuser options give engineers and specifiers full control over light distribution and visual character for each application. Available in lengths from 2ft to 8ft with daisy-chain wiring support up to 600W, the system scales effortlessly to meet the output demands of even the most extensive commercial layouts.
CCT-adjustable and wattage-selectable functions, along with optional dimming and intelligent lighting control integration, allow project teams to precisely match light levels and color temperature to any space. Optional emergency battery backup and PIR sensor modules extend functionality for safety-critical and energy-conscious applications.
Compatible with suspended, surface, and wall mounting, the fixture adapts easily to offices, retail stores, hospitality venues, and institutional interiors. The suspended configuration in particular creates clean, continuous lines of light, contributing to a modern, organized aesthetic within any space.
Fully compliant with international quality and safety standards, the LED Linear Light features a modular design that simplifies installation and maintenance — reducing both project costs and long-term operating expenses. It's a complete linear lighting solution built for global commercial markets, combining architectural-grade performance with the flexibility today's projects demand.

● FAQ
Frosted LED Linear Light is best suited to offices, retail spaces, meeting rooms and other commercial interiors. Its main distinction is frosted diffuser for a softer, more uniform appearance. For a project, match the fixture to the required light level, mounting conditions and control strategy rather than choosing only by nominal wattage.
Start with length, wattage/lumen target, CCT, glare requirement, suspension height and control method. Then compare the exact model specifications, electrical requirements and installation method. For larger projects, a photometric file or lighting layout is the best way to confirm spacing, target illuminance and whether the configuration fits the space.
The main difference is frosted diffuser for a softer, more uniform appearance. Choose this version when that feature directly supports the project requirement; choose clear/lens linear fixtures when the simpler alternative already meets the lighting, installation and control needs. Compare delivered output, optics, controls, mounting and environmental requirements before deciding.
Provide project quantity, installation location, required size, input voltage, target CCT, lumen or wattage requirement, control method, mounting method and destination market. If the project has certification, emergency, IP/IK, dimming or packaging requirements, include them so the correct model can be matched to the request.
5. Can frosted LED linear light be used in continuous runs or custom architectural layouts?
Linear lighting can be planned as individual pendants or as continuous visual lines when the model and accessories support that layout. Connector type, power-feed position, suspension spacing and maximum run length are model-specific, so confirm the run drawing and electrical load before ordering.
