5mm Rainbow LEDs. They have a special chip inside. Can be either fast or slow. See video
- 5mm Rainbow LED
- Fast or slow
- Wire length: 10" standard wire
These are provided with a resistor wired in to ensure both the LED and battery last longer. The resistor is usually near the plug end to unsure it doesn't get in the way. For 3v you can use either a CR2032 or 2 x AAA battery kit but if you are using more than 4-5 LEDs in your circuit you would be best using our 2 x AAA battery kit to ensure nice and bright LEDs and consistent results. Also available in a 6 volt, 9 volt and 12 volt option (with resistor wired in).
***Please Note: If you wish to mix both solid and flashing LEDs off a coin cell battery it is best to run them off separate batteries otherwise there will be carryover of flash to the solid LEDs. AAA sized batteries or higher voltages are unaffected***
