15 ultrabright red, yellow and white LEDs with built-in flickering circuits and assorted lens sizes from 3mm and 10mm.
Perfect LEDs for electronics tinkering and exploration. Safe for direct drive from a CR2032 coin cell. Please use a resistor when driving from a more powerful source.
These LEDs have built-in flickering circuits, and flicker automatically when you supply them with DC power, for example from batteries or the I/O pin of a microcontroller.
LED color Voltage* Current**
Red 1.9V 25mA
Yellow 2.1V 30mA
White 2.7V 30mA
* Typical forward voltage
** Maximum continuous current
