F.378、F.379 and F.367,the entire lamp body is completed by integrated aluminum die-casting, with light source and power supply dual cavity, reduces the heat formation that overlaps with each other, which causing chip premature failure due to excessive temperature. Tempered glass for smooth surface protection, reducing environmental damage to optical and electronic components, effectively extending product lifespan. Body surface is smooth and clean, no protruding heat ribs or columns and concave structures, with self-cleaning function to avoid long term use of leaf stacking and other conditions which cause poor heat dissipation of lamp, resulting in product failure.
