Description
Product Overview
The 5mm flat top concave LED offered by Lighthouse LEDs is engineered for high‑intensity illumination while maintaining a compact footprint. Measuring just 5 mm in diameter, the LED features a flat top concave lens that spreads light across a broad 150‑180° viewing angle, delivering a luminous intensity of 9,000‑11,000 mcd. The device operates at a forward voltage of 3.2‑3.4 V and draws a modest 20 mA, making it compatible with standard Arduino, Raspberry Pi, and other microcontroller power supplies. Its clear white (cool) color temperature provides a crisp, daylight‑like appearance that is ideal for both decorative and functional lighting applications. The through‑hole DIP package simplifies soldering onto prototype boards, perfboards, or custom PCBs, and the robust epoxy encapsulation ensures long‑term reliability even in demanding hobby environments.

Usage
Designed with versatility in mind, this LED excels in a wide range of hobbyist and maker projects. Its high brightness and wide dispersion make it a popular choice for creating festive Christmas lighting strings, where the clear white output mimics traditional holiday bulbs while offering modern efficiency. Model railway enthusiasts use the LED to illuminate scale train interiors, stations, and street scenes, benefiting from the low power draw and easy integration. Remote‑controlled (RC) aircraft, cars, and boats often incorporate the LED for navigation lights, signal indicators, or interior illumination, taking advantage of its lightweight form factor and durable construction. Additionally, the LED is well‑suited for Arduino‑based light‑show installations, wearable electronics, and educational kits that demonstrate basic electronics principles. Its compatibility with standard 3.3 V and 5 V systems means it can be powered directly from most development boards without additional driver circuitry.

FAQ
What is the recommended forward voltage for this LED?
The LED operates optimally at a forward voltage between 3.2 V and 3.4 V. It can be safely driven from a 3.3 V or 5 V supply when paired with an appropriate current‑limiting resistor.
Can I use this LED for outdoor holiday lighting?
Yes. The LED’s clear white output and wide viewing angle make it ideal for outdoor Christmas decorations. For added protection, consider sealing the LED with a clear epoxy or placing it inside a weather‑rated housing.
Is the LED compatible with Arduino and Raspberry Pi boards?
Absolutely. The low forward voltage and modest current draw allow direct connection to the digital I/O pins of Arduino or Raspberry Pi, provided you include a current‑limiting resistor to prevent over‑current conditions.
How long does the LED typically last?
Lighthouse LEDs rates this component for a minimum of 50,000 operating hours at rated current, which translates to many years of continuous use in most hobby applications.
What is the difference between the flat top concave lens and a standard round LED?
The flat top concave lens spreads light more uniformly across a wide angle, reducing hotspots and providing smoother illumination compared to a round LED that tends to focus light in a narrower cone.
