Pixel Strips not lighting

So, I know now that I screwed up by buying strips, but the problem I’m having is that no more than 50 pixels will light up on any strip I have. I’ve tried power injection, I’ve tried straight power, and I’ve run out of ideas.
I have a Falcon F16 V3 and Mean Well 5v 60a power supply.
Each of these is pushing 5.1 volts and 5.2 volts, respectively.

I’m suspecting now that it’s something to do with the data.

Can anyone help me get these lights on? :frowning:

What is your pixel count set to?

Also, just curious: How are you using a Falcon controller AND Pixelblaze?

What is the number you have set the pixels to in the set page.
