Professional-Grade Indicators for Every Project
In the world of electronics, clarity is everything. Our 3mm LED Diodes are designed to provide sharp, high-visibility signaling without overwhelming your power budget. Each diode is housed in a clear, round-head casing that maximizes light dispersion, making them ideal for control panels, model making, and decorative lighting.
Why Choose Our LED Kit?
Unlike generic components, our LEDs are selected for their color consistency and durability. We understand that for hobbyists and engineers alike, "it just needs to work." That is why we provide clear voltage guidelines to ensure your components last for years, not seconds.
Solving the "Burnt LED" Problem
Most DIY failures occur due to incorrect voltage or missing resistors. To protect your project, we recommend using a current-limiting resistor in every circuit. For high-voltage colors like Blue and White, a 4.5V source with a resistor provides the perfect balance of brilliance and longevity. For Red and Yellow, a stable 2V environment ensures your indicators stay cool and bright.

FAQ Section
FAQ Section
Q: Why is my LED not lighting up?
A: Check three things: 1. Polarity (the longer pin is Positive); 2. Voltage (ensure it meets the minimum forward voltage); 3. Connection (ensure the circuit is closed).
Q: Do I need a resistor for these LEDs?
A: Yes. To prevent the LED from burning out, always use a current-limiting resistor, especially when using power sources like 9V batteries or 5V USB ports.
Q: Can I use a 3V coin battery to test these?
A: Red, Yellow, and Green will be very bright at 3V but may have a shorter lifespan. Blue and White work perfectly with 3V sources.
