    Default New on Forum and Pixels

    Hi everyone,

    John here. I am trying to get my feet wet with LED's. Been reading a lot of material and getting more confused. I have what I think is a small and simple project, but not looking that way.

    My significant other has 2 1D X-mas tree outlines made out of 3/8" round rod with incand. lights. The trees are about 30 years old. Wanting to remove the incand and replace with LED's. total length of light string would be around 418", if I use 3" spacing, 140 lights.

    Can I make a string with 140 LED's and how to program.

    I live in Round Rock Tx. Near Austin.

    Any help in giving direction would be appriciated.

    John

    Yes. You could put 3 strings of 50 each together (cut and solder to fit). If you use 12v you could likely get away with powering from one end but I would suggest injecting power at the end of the string as well.

    Thank you. I was told the strings could not be cut which didn't make sense to me. Thanks again.

    John, are you confusing pixels with LED strings? LED strings should not be cut. Pixels can be cut to length.

    LED strip, though, you can most definitely cut. Including pixel LED strips. And may be the most suited to the project.

    This sort of stuff:

    I would pick 10m of the IP30.

    You need to decide whether you want to use
    • Dumb RGB strips/strings (can be cut)
    • Single color LED 12V strips/strings (can be cut)
    • AC LED single color strings (cannot be easily cut)
    • Pixels (can be cut)


    Those choices will determine what type of controller you will need and how to deliver power to the prop.


    2020 Full sized show reworked for the new location. Only adding (famous last words) 13 RBLs that I finally got converted to using pixels
    2019 - Just moved into a new home (yet another change of plans). Will be dim but not dark. Too much to do at the new place to leave time for a show. Dim show (3000 pixels) had regular visits most nights.

    Thank you. That's exactly what I was doing.
