Diffused 5mm Fast Flashing RGB LED - 10 pack [Flashing Effect]

These 5mm diffused RGB LEDs are really fascinating. Unlike regular ones with 4 pins to control 3 LEDs, these have just two leads - power and ground. Once powered, they flash in all colors. Check out the video below to see how they look and the timing. You can't change the 'program' or rate as it's set in a small chip inside the LED. If you need to control the RGB arrangement, we have RGB LEDs that can be easily controlled with a microcontroller. We also offer a version with a slow fading RGB color cycle. These LEDs are quite bright, around 1000 mcd in total. They diffuse well, so you can see the color change from any angle. The forward voltage is about 3.4VDC, and you can use a lithium coin cell like a CR2032, though they'll be a bit dimmer. We don't have a datasheet for current draw at different voltages and colors, but at the 'rated' 3.4V it's about 20 mA and at 3.0V it's about 10mA. They come in a pack of 10. Note that due to manufacturing differences, they won't sync up and will slowly go in and out of sync.

Using these LEDs is simple. Just connect the two leads to a power source and ground. For best brightness, use a power supply with a forward voltage of about 3.4VDC, but a lithium coin cell like a CR2032 also works, though the LEDs will be dimmer. Remember, you can't change the flashing program or rate. Since the LEDs won't sync up because of manufacturing differences, don't expect them to flash in perfect unison. There's no special maintenance required, just keep them dry and away from extreme temperatures. If you want to control the RGB arrangement, consider our other RGB LEDs that can be connected to a microcontroller.
