从Hong Kong供应商批量进口4w-5.5w-7w-9w Led Global Light Bulbs

The 4W, 5.5W, 7W, and 9W LED global light bulbs from Power Alliance Technology Ltd. use concentrated COB (CCOB) light sources for high brightness and improved colour rendering compared with rival products at the same power levels. Each bulb features a plastic housing with an aluminium base plate for heat dissipation, topped by a milky polycarbonate cover that diffuses light evenly. The range is designed as a direct replacement for halogen or metal halide bulbs, cutting energy use by 70 to 80 percent without sacrificing output.

Construction combines a plastic shell and aluminium heat sink to maintain low operating temperatures, extending LED life. The CCOB module delivers a tighter beam with higher luminous intensity than standard LEDs, while the milky PC cover reduces glare. Typical colour rendering index for CCOB modules in this class is 80 to 90 Ra, and standard colour temperatures are 3000 K warm white and 4000 K neutral white. The bulbs emit no ultraviolet or infrared radiation, making them suitable for sensitive displays and artwork.

Common applications include hotel rooms, lobbies, supermarkets, fashion shops, restaurants, offices, art galleries, museums, corridors, exhibition halls, bars, and residential homes. Importers can integrate these bulbs into existing E27 or E26 fixtures to upgrade efficiency. Buyers should confirm base type, beam angle, and dimmability with the supplier before bulk orders, as these parameters are not specified in the listing.

Power Alliance Technology Ltd. is based in Hong Kong, with a registered address at Unit 7-8, 16/f., Wang Cheong Enterprise Center, 65-69 Chai Wan Kok Street, Tsuen Wan. The company operates as an importer, specialising in LED lighting solutions for commercial and residential markets. Its listed products include LED global bulbs designed for energy efficiency and long-life performance.

The supplier profile shows a harbor trust tier but does not provide response rate or average response time data. No additional certifications, production capacity, or client references are stated in the profile, so buyers should request these details directly. The company’s focus appears to be on supplying LED products that meet international standards for energy savings and environmental compliance.
