Unleash Your Creativity with Versatile 5V LED Technology
Whether you are a seasoned electronics hobbyist, a 3D printing enthusiast, or a weekend DIY crafter, these 31mm round LED panel modules are the perfect illumination solution for your custom projects. Operating strictly on a low-voltage 5V DC system, these boards are incredibly versatile. They can be easily powered by repurposed USB cables, standard power banks, AA battery packs, or microcontrollers like Arduino and Raspberry Pi, making them completely safe and adaptable for indoor and portable use.

Vibrant Colors to Match Any Vibe
Available in a stunning array of colors—White, Warm White, Blue, Green, Red, and Purple—these LED discs let you customize the atmosphere of your project. Build a cozy warm nightstand lamp, add an eerie green glow to a Halloween prop, create futuristic blue lighting for a custom PC case, or illuminate miniature models and dioramas with precision.

Ultra-Slim Design for Tight Spaces
Forget about bulky cylindrical bulbs. With a precise 31mm diameter clearly stamped on the board, this ultra-slim disc profile fits easily into custom enclosures, shallow lamp housings, and tight acrylic tubes. Six high-brightness SMD chips are arranged in a radial sunburst pattern on a single forward-facing plane. This ensures a wide 120° beam angle, directing all the light exactly where you want it without wasting energy illuminating the backside. A convenient 5mm center aperture allows for creative mounting options, such as passing wires or standoffs directly through the middle.

Built for Reliable, Long-Lasting Performance
Each module is engineered on a rigid white fiberglass epoxy PCB designed for efficient heat dissipation. Onboard micro-resistors regulate the voltage to protect the LEDs, ensuring consistent, flicker-free brightness over a long lifespan. Consuming only 3 Watts of power, these modules are highly energy-efficient, preserving your battery life during extended portable use.

Effortless Soldering & Installation
Wiring your new lights couldn't be easier. Clearly printed positive (+) and negative (-) polarity symbols are located right next to the integrated solder pads. This straightforward, beginner-friendly design takes the guesswork out of wiring, allowing for a quick, frustration-free connection to your power source.

10-Pack Value Set
Every order includes 10 beautifully crafted LED light boards, giving you plenty of modules to build multi-light arrays, upgrade several small fixtures, or just keep spares in your electronics toolkit.

⚠️ IMPORTANT SAFETY NOTE: These modules are designed for 5V DC ONLY. Do NOT wire them directly into 12V/24V automotive systems (cars, trucks, RVs) or plug them into household AC outlets without using a proper step-down voltage converter (buck converter), as this will instantly burn out the LEDs.
