High-Bay 400W SMD LED Cold-Forged Heatsink

Cooltron’s 400W SMD High Bay Light Cold Forged Heatsink features a unique bio-inspired fish-scale and shark-fin 3D structure that increases surface area, generates micro-vortices, and significantly enhances convective heat transfer.

  • Flexible Installation
    Maintains high efficiency even at non-vertical angles, giving greater flexibility in lighting fixture design.
  • Superior Thermal Conductivity
    AL1070 cold-forged heatsinks (≥99.7% pure aluminum, up to 240 W/m·K) outperform extrusion and die-casting, delivering outstanding heat dissipation for high power LED lighting.
  • Longer LED Lifespan
    Faster PCB temperature stabilization (20–25 minutes) reduces heat buildup, prevents light decay, and prolongs product lifetime.
  • Compact & Lightweight
    High thermal efficiency enables smaller, lighter designs that lower production and shipping costs.
  • Advanced Surface Protection
    Electrophoretic (e-coating) finish ensures exceptional corrosion resistance in harsh environments, superior to plating, powder coating, or anodizing.
  • Versatile Applications
    Perfect for grow lights, high/low bay lights, flood lights, and other LED
