从China供应商批发进口500w 170lm Per Wattage Linear Led High Bay — FOB条款

The 500W linear LED high bay from Tang Song Optoelectronic Co., Ltd. delivers 170 lm/W initial luminous efficacy using Luexon 5050 SMD chips paired with a Mean Well HLG series driver. The fixture accepts AC90-305V at 50/60Hz, covers power ratings from 50W to 500W, and achieves IP65 ingress protection with an aluminum housing and tempered glass cover. Power factor exceeds 0.9, and lumens maintenance is rated at 3% degradation after 3,000 hours of operation.

The aluminum housing provides passive thermal management for the Luexon 5050 package, a mid-power LED platform known for its lumen density and consistency in industrial environments. Tempered glass adds mechanical protection over the optical surface without significant light loss. The Mean Well HLG driver family is a standard choice for high-bay applications, offering universal voltage input and robust surge protection typical of commercial-grade LED installations. The 70,000-hour lifespan projection assumes operation at rated case temperature and standard thermal design.

This high-bay configuration suits warehouses, manufacturing floors, gymnasiums, and retail distribution centres where ceiling heights demand narrow-beam, high-output distribution. Buyers should confirm the beam angle, mounting bracket options, and dimming protocol (0-10V, DALI, or none) directly with Tang Song Optoelectronic. The CE and RoHS certifications stated in the source cover EU market entry; importers into other jurisdictions should request the corresponding test reports and local compliance documentation.

Tang Song Optoelectronic Co., Ltd. operates from 3/F, Zhonghua Industrial Area in Longhua, Shenzhen, Guangdong, placing it within the dense LED manufacturing corridor of southern China. The supplier holds a harbor trust tier on the platform, with a response rate of 0.00% and no recorded average response hours, which indicates that direct communication channels should be tested before relying on platform messaging alone.

The listing emphasises component-level transparency, naming both the LED package manufacturer (Luexon) and the driver brand (Mean Well), which is a positive signal for buyers assessing bill-of-materials quality. No information is provided about factory size, annual output, in-house testing capabilities, or export history, so due diligence should cover these gaps. The seven-year warranty is notable for the LED high-bay category, where three to five years is more common; buyers should request the warranty terms document to understand coverage limits and claim procedures.
