5.5W 400LM 220V A60 LED bulb

This Hangzhou Yokon Solar-LED Lighting Co., Ltd. offering is an A60 form factor LED lamp rated at 5.5W input power with 400 lumen luminous output, designed for 220-240V AC 50Hz electrical systems. The light engine employs a 5.5W MCOB (multi-chip on board) LED source with power tolerance of plus or minus 0.5W and lumen tolerance of plus or minus 20 lumens, delivering efficacy of approximately 72.7 lumens per watt at nominal conditions. The product carries a two-year warranty and claims a lifespan of 35,000 hours with tolerance of plus or minus 300 hours, positioning it as a direct replacement for 50-60W incandescent lamps in residential, commercial, and light industrial applications across 220V markets.

The A60 bulb shape, also referenced as A55 in supplier documentation, follows the classic pear-shaped envelope with Edison screw base, standard for retrofit applications in European, Asian, and Commonwealth markets. The MCOB construction integrates multiple LED chips directly on a thermally conductive substrate, offering improved thermal management and beam uniformity compared to early SMD discrete designs. Lumen maintenance at end of rated life is not specified in the source data, though typical industry expectation for this power class and technology platform is 70% of initial output at 35,000 hours under standard operating conditions. The input voltage range of 220-240V AC implies no integrated voltage regulation for 110V markets, limiting direct application without step-up transformation.

Primary buyers include electrical wholesalers, property maintenance contractors, retail lighting chains, and solar home system distributors seeking efficient 220V general illumination. The compact single-unit packaging (70mm x 70mm x 117mm, 0.12 kg) supports retail distribution, while the outer carton configuration of 50 units (835mm x 235mm x 170mm, 9.5 kg) suits bulk import and warehouse logistics. Hangzhou Yokon operates from Gongshu District, Hangzhou, within Zhejiang Province's established LED manufacturing cluster. Buyers should confirm compliance with target market safety and efficiency regulations, including CE marking status, RoHS conformity, and any local energy labelling requirements, as these certifications are not stated in the available data.
