    Anyone have any tips on power injection on strings with no injection wires ? Or is it just splice and solder

    There should be wires from the last pixel. Use those.

    Ordered from Diy led express and all strings have no extra wires for injection so didnít know if there was a easy way to add or not

    You have to use the negative and positive on the last wire out or order some tees from DIYledexpress. If their connectors aren't wired the same you will need to change the plug.

    If you have connectors that will fit the ones that are on the pixels just connect to the negative and positive and not the data.

    You only need the tees if you intend on running another string. If not then you need a connector so you can add power. You have a choice. If not running another string then just cut off the connector and only connect the power. If running another string you will need a tee.

    How many pixels are on that string? I think what pmiller is referring to is that, many folks (myself included) would just inject the power at the very last pixel and limit the total string length to 100 pixels. If you are going to do 150 pixels per string (three x 50 pixels) as you stated earlier, then you need to have tees OR come up with some other approach. The majority of our display is done with 100 pixels per output on a controller and we send data+power to pixel 1 and then ONLY power to pixel 100. Wherever we go higher than that on the controller output (our window panel matrix units for example have 288 pixels per output), then we use tees to inject the power into the various points along the string.

    Thanks I was running these on roof line edge 150 on garage edge and 169 on main house edge . My problem is everytime I order pixels from a different vender I get different injection points or none at all . The other ones from ray wu only have one injection at the beginning of each string . The ones from rextin have injection on both ends of string makes things a pain .
