### High-Efficiency SMD 3535 & 13W Optical Performance

Driven by top-tier SMD 3535 LED chips, this 6-LED PCB light engine delivers a robust 13W output with superior luminous efficacy. The precision arrangement of the 6 high-power LEDs ensures uniform light distribution, minimizing hot spots and glare, making it the perfect internal light engine for streetlights, floodlights, and high-bay fixtures.

### Advanced Thermal Management & Compact Form Factor

Measuring exactly 72.2×49.5mm, this compact module is built on a heavy-duty aluminum PCB substrate. The high thermal conductivity ensures rapid heat dissipation away from the LED junctions, dramatically reducing lumen depreciation and maintaining architectural-grade stability even in harsh, continuous outdoor environments.

### Engineering Specifications & Compliance

Built to meet rigorous international engineering standards, our lighting modules offer:

• Dimensions: 72.2mm × 49.5mm, precision cut for easy integration.

• Power Rating: 13W optimized for high lumen-per-watt efficiency.
