Import Energy Saving Lamps — Buy in Bulk from Supplier in China

These energy saving lamps are designed as compact fluorescent lamps (CFLs) with integrated ballasts, available in rated powers of 3W, 5W, 7W, 9W, and 11W. Each unit operates at 220V AC with a luminous flux range of 180 to 750 lumens, depending on wattage, and a color temperature of 2700K to 6500K. The base types include E27 and E14, compatible with standard household and commercial fixtures. The lamps achieve a luminous efficacy of 55 to 70 lumens per watt, significantly higher than incandescent equivalents.

The internal components use phosphor-coated glass tubes with low-mercury content, in line with standard industry practices for CFLs. The electronic ballast ensures flicker-free operation and extends service life to approximately 8,000 hours under normal conditions. These lamps meet RoHS guidelines for restricted substances, and their thermal management design prevents premature failure from overheating. While the listing does not specify exact mercury content, typical CFLs contain less than 5mg per unit, consistent with EU and international norms.

These lamps are primarily purchased by distributors serving the retail, hospitality, and office lighting markets in regions with high electricity costs. Buyers often specify them for retrofitting older incandescent fixtures in hotels, schools, and small commercial spaces. Packaging is typically in white boxes of 10 or 24 units, with bulk cartons holding 100 to 500 units. Trade terms include FOB Hangzhou and CIF destination ports, with payment via T/T or L/C. Lead time is typically 25 to 35 days after order confirmation, subject to production scheduling.
