CHZ Lighting - LED Street Light Manufacturer and LED Flood Light Factory Since 2013
Dominican Republic 40,000+ Custom Smart LED Street Lights
A landmark municipal road lighting renovation project in the Dominican Republic, setting a new benchmark for customized overseas smart street lighting solutions. The full fleet uses CHZ-ST29 series across three power ratings, fully UL-compliant, with 0-10V intelligent dimming - engineered to meet the strictest overseas standards for safety, compliance, and intelligent control.
Project Background
A high-stakes urban lighting transformation powered by fully-customized, UL-compliant LED street lights.
A High-Stakes Urban Lighting Transformation
The Dominican Republic municipal road lighting upgrade project represents a large-scale deployment of high-standard, fully-customized intelligent LED street lights for overseas markets.
Using the CHZ-ST29 series across three power ratings - 90W, 120W, and 200W - the entire fleet is equipped with premium Lumileds 3030 LEDs and supports 0-10V intelligent dimming systems.
The project strictly adheres to local municipal electrical codes and UL international safety certification standards, with over 10 custom modifications covering structure, electrical design, processes, labeling, and spare parts planning.
Client Core Pain Points
Off-the-shelf street lights simply couldn't meet the rigorous demands of this overseas municipal project - from compliance to structural compatibility.
UL Compliance Mandate
Overseas municipal projects require full UL certification across SPD, wiring, terminals, connectors, and PCB boards - standard products fall short.
NEMA Interface Mismatch
The project requires 5-Pin NEMA standard bases for smart control integration, which standard street light housings don't support.
Custom Wiring Standards
Overseas engineering has mandatory specifications for cable gauges, terminal types, and mounting methods requiring deep structural customization.
Traceable Identification
Large-scale projects demand standardized process markings and traceable factory labeling - laser engraving plus custom yellow stickers.
After-Sales Logistics
Overseas maintenance is costly and slow. The client contract mandates 0.2% spare parts inventory across all categories.
Smart Dimming Requirement
Municipal roads need 0-10V stepless smart dimming for tiered energy savings and time-based intelligent control strategies.
Customized Solution
Instead of applying a generic product, we engineered a 100% custom solution across six dimensions - perfectly matching the Dominican Republic's strict municipal requirements.
Multi-Power Configuration
Custom-developed CHZ-ST29 series in three power ratings for different road types and traffic densities.
- 90W / 120W / 200W - unified housing & electrical platform
- Lumileds 3030 premium LEDs for high brightness & low decay
- Designed for tropical high-temperature, high-humidity, salt-spray environments
0-10V Smart Dimming System
Full fleet equipped with stepless 0-10V intelligent dimming for municipal energy management.
- Precision brightness control via central management platform
- Time-scheduled energy-saving modes & late-night power reduction
- Single-light control + district cluster management capability
UL-Compliant Electrical Design
Complete electrical architecture upgraded to meet UL/ETL certification and Dominican municipal standards.
- UL-certified SPD surge protection modules
- Independent 600V fuses per phase for fault isolation
- UL white screw connectors + 3 WAGO terminals
- 18AWG 3-core gray cable per engineering spec
- UL-marked PCB boards for audit & compliance
Structural & Process Customization
Multiple structural customizations per client technical agreement - distinct from standard market products.
- Standard 5-Pin NEMA base for smart control expandability
- 50mm extended handle + longer screws for complex pole mounting
- Custom external wiring layout matching overseas installation practices
- Laser engraving + custom yellow label dual identification
Dedicated Spare Parts Program
0.2% of total quantity reserved as spare parts covering all core consumable components.
- Drivers, LEDs, SPD modules, fuses - fully covered
- Addresses the high cost and long lead times of overseas after-sales
- Ensures long-term stable operation post-deployment
Rigorous Testing & Validation
Comprehensive UL testing validates performance, durability, and safety under extreme conditions.
- Dielectric withstand & surge immunity (ANSI C136.2)
- THD, temperature, inrush current, ESD (ANSI C136.37)
- QUV accelerated weathering test
- Salt spray corrosion test (ASTM B117)
