3mm LED Light Kit 500 2Pin Round Red Yellow Green Blue White CESFONJER

Description

Product Overview

The CESFONJER 3mm LED Light Kit is engineered for makers, educators, and hobbyists who demand consistent brightness and color fidelity across a large quantity of components. Each of the 500 LEDs is a 3 mm round, diffused, 2‑pin device that emits a soft, even glow, reducing glare and making it ideal for projects where visual uniformity matters. The kit includes exactly 100 LEDs in each of the five primary colors—white, red, yellow, green, and blue—allowing users to create multi‑color effects, signal indicators, or educational demonstrations without the need to source additional parts.

Manufactured by CESFONJER, the LEDs feature a clear epoxy finish that protects the semiconductor while preserving the luminous output. With a working voltage of 3.0‑3.2 V for blue, green, and white, and 2.0‑2.2 V for yellow and red, the diodes are compatible with a wide range of microcontroller boards, battery packs, and driver circuits. The low power consumption of 0.06 W per LED translates to minimal heat generation, extending the lifespan of both the component and the surrounding circuitry.

Usage

These LEDs excel in a variety of practical applications. In educational settings, teachers can use the color assortment to illustrate concepts such as wavelength, photon energy, and circuit design, giving students hands‑on experience with real components. Hobbyists building custom light displays, wearable electronics, or Arduino‑based projects will appreciate the ready‑to‑use assortment, which eliminates the need to purchase individual colors separately. The compact 2‑pin form factor fits easily onto breadboards, perfboards, and printed circuit boards, making prototyping fast and reliable.

Beyond the classroom and maker‑space, the LEDs are perfect for automotive interior lighting, decorative signage, and low‑power illumination in remote sensor nodes. Their diffused lenses spread light evenly, reducing hot spots and creating a pleasant visual effect for mood lighting or indicator panels. Because the kit is supplied in a sturdy, clearly labeled storage box, users can quickly locate the required color, minimizing downtime during assembly or repair work.

FAQ

What is the recommended driving current for these LEDs?

The LEDs are designed to operate at a forward current of 20 mA. Using a constant‑current driver or a suitable resistor value will help maintain consistent brightness and protect the diodes from over‑current conditions.

Can these LEDs be used with a microcontroller like Arduino?

Yes, the voltage range of 2.0‑3.2 V matches the output of most microcontroller GPIO pins when paired with appropriate current‑limiting resistors. This makes them ideal for blinking, PWM dimming, and color‑mixing projects.

Are the LEDs suitable for outdoor applications?

While the LEDs themselves are sealed with a clear epoxy that offers some moisture resistance, for true outdoor use we recommend additional conformal coating or enclosure to protect against humidity and temperature extremes.

How should I store the remaining LEDs to maintain their quality?

Keep the LEDs in the original kit box, which is designed to protect against static discharge and physical damage. Store the box in a cool, dry place away from direct sunlight to preserve luminous performance over time.

What warranty does CESFONJER provide for this LED kit?

CESFONJER offers a one‑year limited warranty covering manufacturing defects. If you encounter any issues, contact our support team with the purchase details, and we will arrange a replacement or provide troubleshooting assistance.
