5V 31mm Circular Blue LED Light Board Module High-Efficiency Aluminium Substrate LED Panel (Vibrant Blue Light)

Add a cool, futuristic touch to your custom lighting projects with this ultra-compact, high-performance circular Blue 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 custom indicators, ambient accents, gaming setups, and creative DIY models.

Key Features

Vibrant Blue Illumination: Emits a crisp, deep blue light that delivers a striking, modern aesthetic. Ideal for tech-themed setups, sci-fi props, custom ambient backlighting, or unique status indicators.
Ultra-Compact 31mm Ring Design: Features a space-saving circular profile with a practical center hole, allowing for easy integration around mechanical shafts, hardware components, 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 power status beacons, system alerts, marine-themed displays, and customizable control panels.
Creative DIY & 3D Printing: An ideal light source for sci-fi scale models, cosplay armor, custom 3D-printed cyberpunk art, and immersive PC chassis modding.
Gaming & Ambient Accents: Great for specialized under-desk lighting, desk toy modifications, or cool-toned accent light sources for acrylic displays, trophies, and minerals.
