Add vibrant, eye-catching illumination to your custom projects with this ultra-compact, high-performance circular Red LED light board. Measuring just 31mm in diameter with a central hollow cutout, this module is built on a heavy-duty aluminum core PCB for superior heat dissipation. Powered by a safe, universal 5V DC input, it is the ultimate choice for specialized indicators, warning signals, festive decor, and custom DIY setups.

Key Features

Vibrant Red Illumination: Emits a pure, high-intensity red light that is highly visible, making it perfect for custom indicators, ambient lighting, night-vision friendly displays, and creative setups.
Ultra-Compact 31mm Ring Design: Features a space-saving circular profile with a practical center hole, allowing for easy integration around mechanical shafts, hardware, or 3D-printed mounts.
Premium Aluminum PCB Substrate: Engineered with a high-thermal-conductivity aluminum base that rapidly draws heat away from the LEDs, ensuring a prolonged lifespan, high stability, and reliable performance.
High-Efficiency SMD LED Array: Equipped with 6 high-power surface-mount LEDs arranged in a radial layout to provide uniform, shadow-free, and directional light distribution.
Safe & Universal 5V DC Power: Runs efficiently on standard 5V low voltage. Easily power the module via USB cables, power banks, 5V phone chargers, or lithium battery packs.
Durable Solder Joint Ready: Features clearly marked, pre-tinned positive (+) and negative (-) soldering pads for secure wire connections.

Ideal Applications

Custom Electronic Indicators: Perfect for crafting DIY warning beacons, signal lights, exit signs, and status displays for machinery or models.
Creative DIY & 3D Printing: An ideal light source for sci-fi models, cosplay props, custom 3D-printed cyberpunk art, and festive Halloween or Christmas decor.
Automotive & Tailored Accents: Great for micro-accent illumination inside vehicle gloveboxes, custom trunk lights, or emergency night-vision dashboard enhancements.
