The embedded downlight adopts PA material for the lamp body, which has excellent electrical insulation performance. The outer shell is non-conductive, effectively reducing the risk of leakage. PA material also has outstanding anti-corrosion and salt spray resistance, is less prone to oxidation and rust, and has a longer service life. Its uniform heat conduction can prevent local overheating, further extending the lifespan of the LED beads. In addition, PA material is lighter in weight, significantly reducing the load on the ceiling, making it particularly suitable for light steel keel ceilings or renovation of old houses, providing more convenience for construction.
