Description: 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 warm white 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.

Dimensions: 10m

  • These are really nice little strings, and brought them in to distribute in Canada at Solarbotics. Part of what we do is play with most of the things we bring in, so while we played with these, we tested them at several voltages (3, 4.5, 6, 7.6V), measuring the current consumption and the lux output of the last LED in the string.

    Feel free to check out the results pdf.

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

  • These appear to be just what I was looking for to decorate my front arbor- do you have any idea how they would survive outdoors? Seattle has a fairly mild climate…

  • Noob question: How much power will these draw when lit?

    The datasheet states a 0.05W scattered distribution (which I assume is some kind of probability curve). I also assume that rating is per LED, so for a full string with 100 LED I’m looking at 5W, plus whatever is going through the resistor of course. Am I off track here?

    • I decided to buy these and find out for myself.

      Out of the bag, I connected them to by power supply and hit them with 3V…and nothing. I re-stripped the wires to ensure I had connection through the epoxy, and powered them up again. Nothing. I slowly ratcheted up the voltage from 3, past 3.4V to 3.7V when they finally, and dimly lit up. They didn’t really begin to illuminate in any bright fashion until I got to 6V, and seemed to level off in brightness around 9V. I didn’t go beyond 9V.

      I noted the current draw from the power supply at 6V was about 70 mA, putting the power at about 0.42 W. I’ve assumed then the 0.016 mA draw is per echelon of LEDs (4 echelons of 25 LEDs each, according to the data sheet) => 4 x 0.016 A = 64 mA.

      I wonder if I hit these with a constant current source I could get them to be brighter at a lower volatage? I have some LM317’s that are in need of a project, so I guess I know what I’m doing tonight!

  • I removed the 39 ohm resistor that came with my soft white string and replaced it with two 100 ohm 1 Watt resistors in parallel (50 Ohms). I powered the string with a 9V DC adapter (just like TOL-00298) using a DC barrel jack adapter (PRT-10288). Everything stays within tolerances (nothing gets to hot or overloaded) and it made a very nice light for my wife’s art deco display cabinet. Its been in use for two weeks without problems as of the time of this message being posted. Very Nice!

  • Why does the video state 12V working voltage and your product ‘Note’ state 3-3.4V?

    • Because the video has it wrong. Whether it was the ‘water cooling’ in the video or sheer luck or there was never actually 12V on the string, applying 12V to these will typically result in a very hot, if not quickly burnt out, resistor.

  • How flexible/bendable is the string and what material is it made of?

    • It’s not string, it’s a thin metal wire. It coils up pretty nicely and is rather flexible in my opinion.
