Hps high pressure sodium lamps manufacturers

When sourcing HPS lamps, you must prioritize Luminous Efficacy, typically ranging from 100 to 150 lumens per watt. For horticultural applications, focus on Photosynthetic Photon Flux (PPF) rather than just lumens. Ensure the Color Rendering Index (CRI) meets your specific environment needs, usually around 20-30 Ra for standard HPS. Additionally, verify the rated average life, which should ideally be between 24,000 and 32,000 hours to minimize maintenance costs.

Compatibility hinges on the Ballast Type. You must confirm whether the lamps require a Magnetic Ballast or an Electronic Ballast. Check the Ignitor requirements and ensure the Operating Voltage (e.g., 110V, 220V, or 400V) matches your local grid. Using a lamp with an incompatible ballast can lead to premature failure or explosive shattering.

For the European market, CE marking and RoHS compliance (restriction of hazardous substances, particularly mercury) are mandatory. For North America, look for UL or ETL listing to ensure safety standards. If the lamps are intended for street lighting, they should adhere to IEC 60662 standards which specify performance and safety requirements for high-pressure sodium lamps.

HPS lamps are primarily used for Street Lighting, Industrial Warehousing, and Indoor Gardening (Flowering Stage). Their main advantage is high energy efficiency and strong fog penetration due to the yellow-orange spectrum. In horticulture, they provide the red-spectrum light necessary for stimulating fruit and flower production.

The biggest risk is physical breakage due to the fragile glass envelope and internal arc tube. You should mandate Double-Wall Corrugated Packaging and individual cell inserts. Ensure the supplier uses Drop-Test Certified packaging. Furthermore, since HPS lamps contain small amounts of Mercury, they are classified as Category 9 Miscellaneous Dangerous Goods in some jurisdictions; ensure your freight forwarder is experienced in handling hazardous material documentation.

Request a Batch Test Report for every shipment. Negotiate a contract that includes a Defect Rate Guarantee (typically less than 1-2%). Use Made-in-China.com's Secured Trading services to hold payment until a Third-Party Pre-shipment Inspection (PSI) confirms the lamps meet the agreed-upon lumen output and vacuum integrity.

Check the HS Code (typically 8539.32) for your specific country to determine import tariffs. Be aware of Anti-Dumping Duties that some regions impose on Chinese lighting products. Always clarify the Incoterms (FOB or CIF); for fragile goods like HPS lamps, FOB is often preferred so you can choose a logistics provider with better insurance coverage for glass breakage.
