Brighten your custom lighting projects with this ultra-compact, high-performance circular LED light board. Measuring just 31mm in diameter and built on a heavy-duty aluminum substrate for superior heat dissipation, this module delivers exceptionally bright and stable illumination. Powered by a safe, universal 5V DC input, it is the ultimate plug-and-play light source for DIY enthusiasts, makers, and custom lamp manufacturers.

Key Features

Ultra-Compact 31mm Circular Design: Perfectly sized for micro-lighting fixtures, mini puck lights, custom flashlights, and intricate 3D-printed or CNC-machined lamp bases.
Premium Aluminum PCB Substrate: Engineered with a high-thermal-conductivity aluminum base that rapidly draws heat away from the LEDs, ensuring a prolonged lifespan and stable brightness.
High-Efficiency SMD LED Array: Equipped with 6 high-intensity 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 AA/lithium battery setups.
Dual Color Temperature Options: Available in crisp White for high-visibility tasks or cozy Warm White for gentle, relaxing ambiances and custom nightlights.
Durable Solder Joint Ready: Features clearly marked, pre-tinned positive (+) and negative (-) soldering pads for secure wire connections.

Ideal Applications

Cabinet & Display Lighting: Perfect for building or upgrading mini under-cabinet puck lights, jewelry showcases, and display shelves.
3D Printing & DIY Crafts: An ideal internal light source for custom 3D-printed lithophanes, mini moon lamps, desktop ornaments, and resin art.
