Flood light housing

The most critical material for flood light housings is ADC12 or A380 die-cast aluminum, which provides excellent thermal conductivity and structural integrity. Ensure the housing features a powder-coated finish (typically AkzoNobel or Tiger brand) to prevent corrosion and UV degradation in outdoor environments. For high-power applications, the heat sink design must have sufficient surface area to maintain a junction temperature below 85°C.

For outdoor flood lights, an IP65 or IP66 rating is the minimum requirement to ensure protection against dust and powerful water jets. Additionally, an IK08 or IK09 impact resistance rating is vital for durability in public spaces. Depending on the target market, verify compliance with CE (LVD/EMC), RoHS, and UL/ETL standards. If the housing includes a glass cover, it must be tempered glass to meet safety regulations.

The housing must be compatible with standard LED PCBs (like 3030 or 5050 chips) and optical lenses (60°/90°/120°). Look for designs that feature pre-drilled holes and silicone gaskets for easy assembly and a reliable seal. A breathable valve (vent) is highly recommended to balance internal and external pressure, preventing moisture condensation inside the lens.

Housings are generally categorized by wattage: Slim series (10W-50W) are ideal for residential gardens and signage; Industrial series (100W-300W) are used for warehouses and parking lots; and High-mast series (400W+) are designed for sports stadiums and ports. Ensure the mounting bracket (U-bracket) is thickened to support the weight and resist high wind loads.

Always request a pre-shipment inspection (PSI) by a third party to verify the die-casting density (checking for air bubbles/porosity) and waterproof sealing. On Made-in-China.com, prioritize Audited Suppliers who provide full material analysis reports (MTR) and salt spray test results to ensure the housing won't rust within 2 years.

Focus on tooling/mold ownership if you require a custom design; clarify who owns the mold and the mold life expectancy (usually 50,000-100,000 shots). For standard models, negotiate based on weight (aluminum price index) rather than just unit price, and aim for a 15-20% discount on orders exceeding 2,000 units.

Flood light housings are heavy and prone to scratching. Insist on individual bubble wrap packaging and reinforced 5-layer corrugated cartons on fumigated pallets. Since these are high-density goods, Sea Freight (LCL/FCL) is the most economical method. Ensure the Incoterms are clearly defined, with FOB or CIF being the most common for bulk hardware.

Utilize Secured Trading Services provided by Made-in-China.com to protect your deposit. Never wire full payments upfront; a standard 30% deposit and 70% balance against the Bill of Lading (B/L) is the industry norm. Verify that the supplier's bank account name matches the company name on their business license.
