Frequently Asked Questions

Q: What is the difference between a flat top LED and a standard round-top LED?

A: A flat top LED has a flat lens rather than a domed one, which gives it a much wider viewing angle — up to 180° — making it ideal for applications where light needs to spread broadly, such as signage, displays, and ambient decorative lighting. Standard domed LEDs typically have a narrower, more focused beam.

Q: Do I need a resistor when using these 3mm flat top LED diodes?

A: Yes. Always use a current-limiting resistor in series with each LED to prevent excess current from damaging the diode. The correct resistor value depends on your supply voltage and the LED's forward voltage (1.8–3.4V) and current rating (20mA typical). Many online LED resistor calculators can help you find the right value quickly.

Q: Are these LEDs compatible with Arduino and Raspberry Pi projects?

A: Absolutely. These 3mm flat top LEDs operate at 1.8–3.4V forward voltage at 20mA, making them perfectly compatible with Arduino, Raspberry Pi, and other microcontroller GPIO pins (typically 3.3V or 5V with a resistor). They are a popular choice for indicator lights, button backlighting, and custom display panels.

Q: How many LEDs come in a pack and what colors are available?

A: Each pack contains either 100 or 200 LEDs, depending on the option you select. Available colors include Warm White, Red, White, Blue, Green, Yellow, UV, Pink, and Orange — giving you plenty of variety for any creative or functional lighting project.
