need help on identify seed pixels

[frankpeter2006]

Hi all — three years ago I bought Pebble Seed Pixels. I have both 5 V and 12 V . While troubleshooting with a Raspberry Pi, I messed the pixel strings . How can I identify which are 12 V and which are 5 V? both wire size are same.
Thank you for your help.

If it doesn't light on 5V try 12V We may be able to tell from looking at the exterior, but often times not.

Key point there, try the lower voltage first. 12V into a 5V may not end well.

12V into a 5V may not end well.

This has not been tried many times that I know of, but there was an incident last year (https://auschristmaslighting.com/threads/help-with-seed-pixel-and-wled-voltage-power-issue.17015/) where someone got pixels that were 5V but mislabeled as 12V. They worked a little but looked weird and kept burning out w/ wisps of smoke... so it didn't end well for a few of the pixels but it did end well in the sense that we identified what they really were.

LOL, Ya I identified my pixels are 5V, unfortunately there was a little smoke and now they won't light
