从China供应商批量进口2u Energy Saving Lamp

The 2U Energy Saving Lamp from Wuxi Arclights Trading Co.Ltd is a compact fluorescent lamp (CFL) built around a twin-U discharge tube geometry, designed for retrofit into standard Edison-screw or bayonet fittings. Power ratings span 5W to 25W, with a declared wide-voltage input of 100V to 250V accommodating 50 Hz and 60 Hz mains supplies. Colour temperature is customisable on request, indicating the supplier offers phosphor blends across warm white (2700K-3000K), neutral white (3500K-4000K) and cool daylight (5000K-6500K) ranges typical of tri-phosphor CFL formulations. The 2U form factor yields a compact envelope shorter than spiral equivalents, suiting luminaires with restricted depth.

Lamp construction comprises a glass twin-U arc tube fused to a plastic housing containing the ballast and starter electronics. Electrode emission mix and mercury amalgam dose determine lumen maintenance and cold-start performance, though these parameters are not specified in the source data and should be requested. The wide voltage range implies a switched-mode or wide-range electronic ballast rather than simple choke designs, which generally delivers power factor above 0.5 but may require correction to meet IEC 61000-3-2 harmonic limits. Typical 2U CFL efficacy ranges from 50 to 65 lumens per watt, with rated life between 6,000 and 15,000 hours depending on switching cycle frequency and ballast thermal management. The supplier states a longer lifespan than traditional incandescent bulbs, which is consistent with CFL technology but requires quantified data for procurement decisions.

Application environments include residential, office and retail spaces where operating hours justify energy-saving retrofit. The 5W to 15W variants suit task and accent lighting; 18W to 25W units replace 75W to 125W incandescent equivalents for general illumination. Buyers should confirm lamp dimensions against existing downlight or bulkhead cut-outs, as 2U tubes vary in overall length and diameter between manufacturers. Packaging, MOQ and lead-time details are absent from the source and must be confirmed directly with Wuxi Arclights Trading Co.Ltd. The supplier is located in Wuxi New District, Jiangsu Province, with proximity to Shanghai Port and Nanjing Lukou International Airport for export logistics.

Wuxi Arclights Trading Co.Ltd is registered at Room 409, Block 2, Science and Technology Park, New District, Wuxi City, Jiangsu Province, China, postal code 214000. The address indicates an office or trading-company location within a technology park rather than a manufacturing plant, suggesting the firm may operate as a trading house or assembler sourcing glass tubes, ballasts and housings from sub-contractors. Response rate and average response hours both read zero in the available data, so buyers should initiate contact through multiple channels and allow for time-zone delays in communication.

No factory ownership, production-equipment list, ISO certification, revenue, employee count or client reference is provided in the source data. The 'harbor' trust tier and 'imported' supplier classification signal that standard verification steps are necessary. Buyers should request business licence, export licence and any CCC (China Compulsory Certification) or CB test reports for the lamp range. Given the trading-company address structure, verify whether the supplier holds its own manufacturing licence or sources from a partnered factory, and obtain that factory's name and audit status if applicable.
