The ST09 Series combines industrial-strength glass optics with adaptive installation systems for complex urban environments. Delivering up to 185 lm/W efficacy, these lights feature modular Zhaga/NEMA 7-pin sockets for plug-and-play smart upgrades while outperforming HPS lamps by 70% energy savings (e.g., 70W replaces 250W HPS). With IP65 weather resistance and tool-free driver access, they thrive in coastal, industrial, and historic districts.
