Customer Comments

  • Are these compatible with any of the lilypad boards?

  • So you can not make these lights blink slow or fast?

  • I received my lights today - YEY!!! I am confused about the battery voltage needed to power this string of lights. I used the button cell 3V battery I ordered for use in my Lilypad switched coin cell battery holder and the lights worked fine. Is it that they would be brighter at a higher voltage? I don’t want to burn them out with too much voltage, I am going to try and use this string of lights in the hem of a dress, and need to keep things simple and small, and if I could use the coin cell battery holder, life would be much simpler. Any thoughts? Thanks!

  • At 5V the 51 ohm current limiting resistor this string light uses doesn’t exceed it’s spec. (assuming it is a ¼ watt resistor). It drops about 3V with 59 mA of current through it. You can power the string with an old unused 5 VDC cell phone wall wart.

  • I’m a bit confused. The description says these run off of 3V, and not to use 12V. The video had them running off of 9V batteries. Any suggestions?

    • Go with the lower voltages. 3.7v lipos work great with these. The spec sheet originally said 12v, but we had a lot of customers burning out their lights at those voltage levels.
