Features of Ultra Narrow Rigid LED Strips
1. Ultra Narrow 4mm PCB for Compact Lighting Designs
Built with an ultra-slim 4mm FR-4 PCB, this rigid LED strip is designed for installations where space is extremely limited. Its compact profile allows easy integration into slim light boxes, narrow aluminum channels and precision lighting structures without sacrificing brightness or reliability.
2. High-Efficiency SMD3528 LEDs with Uniform Illumination
Equipped with premium SMD3528 LEDs, the strip delivers stable brightness, excellent color consistency and smooth light distribution. The 120° beam angle helps eliminate visible hotspots, creating clean and professional illumination for commercial displays and architectural lighting.
3. Flexible 42 LED & 51 LED Versions
Available in both 42 LED and 51 LED configurations, this series allows customers to choose different brightness levels while maintaining the same compact dimensions. The two variants are ideal for different light box depths and project requirements.
4. Durable Double-Sided FR-4 PCB Construction
The high-quality double-sided FR-4 PCB offers excellent mechanical strength and thermal stability, ensuring consistent performance and long service life even during continuous operation.
