The ST11 Series revolutionizes urban lighting with 190 lm/W peak efficacy in a compact die-cast aluminum body – 35% smaller than conventional street lights (e.g., 20W: 380×160×77mm). Designed for space-constrained installations, it delivers 70% energy savings versus HPS lamps (30W replaces 100W HPS) while integrating CLO technology and IP66/IK10 resilience for harsh environments (-40°C to 45°C).
