Is a very different type of LED light beads. Each has three individual LEDs connected to a dedicated microcontroller inside the LED. There are no multiple connection pins, just two leads - power and ground. When powered on, the LED beads will automatically perform a slow rainbow color gradient cycle. There's no way to change the program or rate at which the influence occurs; it's burned into a small microprocessor chip inside the LED itself.

Inside each 10mm LED module is a red, green and blue LED bead element, and a tiny microcontroller that executes the flash sequence. The color cycling process takes approximately 11 seconds to restart and repeat the sequence.

The LED light beads have a clear housing with a viewing angle of 42 degrees. The intensity of the output varies by color. Red (620-630 nm) has a luminous intensity of 1,200 to 1,500 mcd, green (515-525 nm) has a luminous intensity of 1,900-2,300 mcd, and blue (460-470 nm) has a luminous intensity of 1,500-1,800 mcd

Multiple LED lamp beads
When running multiple color cycling LEDs, the connection process is the same as for a single LED.

Each LED requires its own individual current limiting resistor connected in parallel as shown.

From the drop resistor chart, refer to the supply voltage you will be using, and specify the resistor value.

The recommended resistors will limit the total LED current to approximately 20mA.

If multiple color changing LEDs are used in a display, the color changing patterns will not be synchronized and over time they will either be in sync or out of sync with each other. This is due to the manufacturing process. If you need a simultaneous display, consider the WS2812 LED and light strip.

10mm color-changing LED light beads have two connecting pins for power supply. As with standard LED bulbs, one pin is the anode (positive) and the other is the cathode (negative).

The lengths of the two pins are slightly different. The shorter of the two pins is the cathode (negative) and the longer is the anode (positive).

This method of identifying anodes and cathodes on an LED is universal. At one time, the flat surface on the LED side was used for identification, but in recent years this method of identification has become less reliable.
