LED String Lights - Red (10M)

These LED string lights are a great way to add light to any project with little to no soldering required. The insulated strings come in 10m lengths with one red LED every 10cm for a total of 100 LED's, all you have to do is add 3-3.4V and they are ready to shine.

Note: 3-3.4V is the the working voltage of these strings. Please do not use 12V.

LED String Lights - Red (10M) Product Help and Resources

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

2 Electrical Prototyping

Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

    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 1/4 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.
