Description: This is the LilyPad Rainbow LED strip, a simple seven pack of every LilyPad LED that we have, each still attached to a PCB structure letting you take it apart at your leisure to be sewn into clothing or whatever else you can dream up.

Note: The purple LED has a much higher voltage drop than other LilyPad LEDs so it will be dimmer than the others. What’s voltage drop? Click here and get your learn on!

Note: A portion of this sale is given back to Dr. Leah Buechley for continued development and education of e-textiles.

  • 1x Red LilyPad LED
  • 1x Blue LilyPad LED
  • 1x Green LilyPad LED
  • 1x Yellow LilyPad LED
  • 1x White LilyPad LED

  • How do you unsnap these things? Should it be done by hand? With tools?

    • Well you could use your fingers but that might be hard. Using some needle nose pliers [like these https://www.sparkfun.com/products/8793] should help remove the LEDs PCB’s Rainbow Strip. Just grip the PCB that does not have the LED with the pliers and hold the LED with your index finger and thumb on your other hand. By bending the PCB along the pre-cut lines, this should break apart the PCB strip holding the LEDs together. Make sure to bend away from the LEDs so that the pliers does not apply force on the LEDs.

  • I’m new to this, but I’ve done the reading and I don’t understand the purple being less bright. In the data sheets, the forward voltage for white is 3.3, max 4V. green is 3.2, max 3.8. for purple it’s 2.8, max 3.6. Pink was 1.9 max 2.5. So how does purple have a higher voltage drop than the others? How do I understand this when reading the data sheets? Is there another value to reference?

    • Sorry this response is so delayed, but you’re probably not the only person wondering, so here’s an answer! We oversimplified (in the interest of brevity; not misinformation!) when we attributed the brightness solely to forward voltage. There are a lot of factors that contribute to LED brightness, and it’s difficult to control for all of them.

      We sourced the brightest purple LEDs we could find, and they’re still just not all that bright- it was important to us to make sure that the product description reflects it, but it’s hard to go into an in-depth description of why in that space. In answer to your question about datasheets, the piece of information on a datasheet that will best inform you about brightness is the brightness or luminous rating, which is expressed in millicandelas. You’ll find that on the purple LED datasheet on page 5, at the top.

      Still, datasheets aren’t always as perfectly accurate as we’d like, and the number just isn’t as helpful as the visual in some cases, which is why it’s so important to us to photograph products like this. We want you to be able to see what you’re getting!

Love them!!

These were used to brighten up some ugly lanyards that we have to wear to school everyday. They definitely did the trick!!! It has worked as a great advertisement for my e-textiles club after school:)
