Ignitor for high pressure sodium lamp

Buyers must prioritize voltage compatibility (typically 220V-240V or 380V-415V) and wattage range (e.g., 70W to 1000W). Ensure the ignitor provides a peak pulse voltage sufficient to strike the arc, usually between 3.5kV and 5.0kV. Additionally, check the maximum cable capacitance (measured in pF) to ensure the ignitor can function over the distance between the ballast and the lamp.

For global trade, ignitors must adhere to IEC 60926 and IEC 60927 standards, which govern safety and performance requirements for starting devices. For the European market, CE marking and RoHS compliance are essential to ensure the absence of hazardous substances. North American markets may require UL or CSA certification to meet local electrical safety codes.

Superimposed ignitors generate high voltage without putting stress on the ballast windings, making them ideal for long-distance installations. Impulse ignitors use the ballast as a transformer to generate the pulse; while often more cost-effective, they require the ballast to be specifically designed to withstand high-voltage pulses. Choosing the wrong type can lead to premature ballast failure.

Ignitors are sensitive to thermal stress. Ensure the product has a high Tc (case temperature) rating, typically up to 105°C. For outdoor or industrial use, verify the IP (Ingress Protection) rating; if not housed within a sealed luminaire, an IP65 rating is recommended to prevent moisture and dust entry, which are leading causes of short circuits.

Request a batch test report and a VDE or ENEC certificate from the supplier. Before placing a bulk order, purchase samples for aging tests (running the ignitor for 48-72 hours under load). On Made-in-China.com, prioritize Audited Suppliers who have undergone third-party on-site inspections to verify their manufacturing capabilities.

The primary risks are electrostatic discharge (ESD) and moisture damage. Ensure the supplier uses anti-static packaging and vacuum-sealed bags if shipping by sea. For large volumes, use palletized shipping with moisture-proof film to prevent damage during long-transit maritime routes.

HPS technology is mature, so margins are thin. Negotiate based on annual volume rather than single orders to secure a 10-15% discount. If the MOQ (Minimum Order Quantity) is too high (e.g., 500+ units), suggest a staggered delivery schedule or ask for 'neutral packaging' to reduce the supplier's setup costs.

Always use Secured Trading Services provided by platforms like Made-in-China.com to ensure payment is only released upon confirmation of shipment. For first-time orders, avoid 100% upfront payments; a 30% deposit and 70% balance against the Bill of Lading (B/L) is the industry standard for protecting buyer capital.
