Adjustable High-Efficacy LED Street Light (Model: ZL-ST22D) | IP09 & IK09 Rated

Product Overview

The ST22D Adjustable LED Street Light is a premium, high-performance urban lighting solution designed to meet the rigorous infrastructure demands of markets across Europe, the Americas (especially South America), and Southeast Asia.

Unlike standard solar models, the ST22D is a powerful AC-powered LED street light operating on a wide voltage range (90-305V). It features a highly durable ADC12 die-cast aluminum body with Akzo powder coating, an innovative tool-free buckle design for easy maintenance, and an adjustable arm that supports both horizontal and vertical installations. With an outstanding luminous efficiency of 170-180 LM/W, it provides superior, uniform illumination for highways, urban roads, and residential areas.

Key Features & Benefits

• Superior Heat Dissipation: Constructed from ADC12 die-cast aluminum with a large heat dissipation area. The structure is optimized using advanced FEA technology to realize fast heat dissipation via thermal air convection, ensuring long-lasting LED performance.
• Tool-Free Buckle Design: Features a tool-free power box opening for effortless maintenance. The thermal and electrical separation design includes a built-in knife switch that automatically powers off the unit when the cover is opened, maximizing safety.
• Ultra-High Light Efficacy: Equipped with high-lumen 3030 LED chips, delivering an impressive 170-180 LM/W. The wide illumination range ensures no dark spots or light spots, providing highly uniform light distribution.
• Adjustable Arm Design: The 90° adjustable die-cast aluminum lamp holder allows for flexible installation, supporting horizontal, vertical, and wall-mounted setups.
• Exceptional Durability: The lamp surface utilizes an Akzo powder coating process that does not peel and is highly corrosion-resistant. It boasts an IK09 protection level and operates reliably in extreme ambient temperatures from -40°C to +45°C.
• Advanced Optics: Features a UV-proof optical PC lens and a tempered glass cover with high light transmittance. Type II and Type III beam angles are available to suit various road widths and applications.
• Surge Protection: Built-in SPD (Surge Protection Device) offering 10KV/20KV protection against electrical spikes.

Ideal Applications

With its streamlined, windproof design and versatile optics, the ST22D series is perfectly suited for:

• Urban roads and main streets
• Expressways and highways
• Residential areas and communities
• Courtyards, parks, and squares
• New rural construction projects

Safety & Maintenance Cautions

• The installation must be completed by a professional electrician.
• Do NOT dismantle the product without authorization; it may be dangerous.
• Do NOT look directly at the high-intensity light source with the naked eye to avoid eye damage.
• For outdoor lighting, waterproof measurements must be strictly applied to the cable terminals to ensure long-term safety and safe operation.
