9w led bulb

When sourcing a 9W LED bulb, you must prioritize Luminous Efficacy, which should ideally be ≥90 lm/W to ensure energy efficiency. Check the Color Rendering Index (CRI); for residential or retail use, a CRI >80 is standard, while CRI >90 is preferred for high-end applications. Additionally, verify the Driver Type (IC constant current vs. RC capacity-resistance), as IC drivers offer better stability and a longer lifespan by protecting against voltage fluctuations.

Compliance varies by target market. For the European Union, bulbs must have CE (LVD/EMC) and RoHS certification, and meet the new ErP (Energy-related Products) requirements. For the United States, UL or ETL listing is crucial for safety, and Energy Star certification is recommended for tax incentives and consumer trust. For the Middle East, look for SASO or G-Mark compliance.

Heat is the primary enemy of LED longevity. Ensure the bulb uses a Thermal Plastic-coated Aluminum or Ceramic housing rather than pure plastic. Request a LM-80 report for the LED chips, which tracks lumen maintenance over time. A high-quality 9W bulb should have a rated lifespan of at least 25,000 to 50,000 hours with a warranty of 2-5 years.

A 9W LED bulb typically replaces a 60W incandescent bulb, making it ideal for general indoor lighting, desk lamps, and hallways. You should specify the Beam Angle (e.g., 270° for omnidirectional lighting or 30-60° for spotlights) and Color Temperature (CCT), ranging from Warm White (2700K-3000K) for cozy environments to Cool White (6000K-6500K) for task-oriented spaces.

The most significant risk is Quality Inconsistency between samples and bulk orders. Suppliers may swap high-quality San'an or Epistar chips for cheaper alternatives in mass production. To mitigate this, use Third-party Inspections (like V-Trust or SGS) to perform a Function Test and Hi-Pot Test before the final balance payment is made.

For a standard 9W LED bulb, the MOQ is usually 1,000 to 3,000 units to cover custom packaging costs. When negotiating, focus on the Total Cost of Ownership (TCO). Ask for a tiered pricing structure (e.g., 5,000 vs. 10,000 units) and request that the supplier includes 1% spare units free of charge to cover potential dead-on-arrival (DOA) items during shipping.

LED bulbs are fragile and sensitive to moisture. Ensure the supplier uses 5-layer corrugated export cartons and individual color box packaging with internal supports. For sea freight, request Palletization to reduce manual handling damage. Ensure the HS Code (853952) is correctly declared to avoid customs delays and verify if your country imposes Anti-Dumping Duties on Chinese LED products.

Always conduct transactions through Secured Payment services provided by Made-in-China.com. Avoid direct transfers to private bank accounts. Prioritize Audited Suppliers who have undergone on-site verification of their manufacturing facilities and financial standing to ensure they are a legitimate factory rather than a small trading company.
