码头堆场是照明最严酷的应用：海风盐雾三个月腐蚀一套普通灯具，吊机作业时的震动让灯具连接件天天松动。
堆场水平照度≥20lx、装卸作业面30lx（垂直照度≥30lx识别集装箱号）；灯具执行C5-M海洋性防腐涂层、IP66、振动等级M3；高杆灯35-40米升降式配双卷扬保险。
我们的港口灯具通过2000小时盐雾实测，铝压铸一体成型灯体+316不锈钢紧固件，在沿海码头已服役超过6年无腐蚀。
Port yards are the harshest lighting application on earth: sea salt corrodes ordinary luminaires in three months, and crane vibrations loosen mountings daily.
Yard horizontal illuminance ≥20 lx, working faces 30 lx (vertical ≥30 lx to read container numbers); luminaires with C5-M marine coating, IP66, vibration class M3; 35-40 m raising-lowering masts with dual-winch safety.
Our port luminaires passed 2000-hour salt-spray testing — die-cast one-piece bodies with 316 stainless fasteners running corrosion-free on coastal terminals for 6+ years.
