100PCS 5mm RGB Flashing LED Diodes – Rainbow Multi-Color Bulbs

Q: What is the difference between the fast and slow flashing RGB LED diodes?

Both types are self-flashing RGB LEDs that automatically cycle through red, green, and blue colors. The fast-flash variant cycles through colors at a quicker rate, creating a rapid rainbow strobe effect, while the slow-flash variant transitions more gradually — ideal for subtle, ambient decorative lighting. Each pack of 100 includes a combination of both modes.

Q: Do these 5mm RGB LED diodes require a special driver or controller?

No external controller is needed — these are self-flashing diodes with a built-in IC chip that drives the color-cycling effect automatically. Simply connect to a 3V DC power source (within the 2.2–3.0V forward voltage range) with an appropriate current-limiting resistor and they will begin flashing on their own.

Q: Are these LEDs suitable for use with Arduino or breadboard projects?

Yes! The 5mm through-hole package is breadboard-compatible and works great with Arduino, Raspberry Pi, and other microcontroller platforms. Just use a suitable resistor to keep the current within the rated 30mA maximum, and you're ready to go.

Q: How many LEDs are included and what colors do they emit?

Each order includes 100 pieces of 5mm round-lens LED diodes. Every LED is an RGB self-flashing type that cycles through red (620–630 nm), green (520–530 nm), and blue (460–465 nm) automatically — delivering a full rainbow multi-color effect without any extra wiring or programming.
