4 Wire Pixels - Are they worth it ?

[@davidbergmann987]

Fantastic video! Thanks for the great explanation and demonstration.❤

Thanks makes things a lot clearer on how it all works

Thanks Greg. Great info.

One thing on the power injection - whilst they draw less current, they require a higher voltage to operate than standard resistor 12V pixels. The latter will tend to operate down to 5 or 6V at the end of a string, whereas these need a minimum of 9V due to the three LEDs being in series - so it's likely they will have similar performance overall from a power injection perspective. It should also be noted that due to this series arrangement, that they use the same power whether it's 100% red, yellow or white (R only, R+G, R+G+B) - so that needs to be considered with the "oh im not running full white so i'm good" statement - full red (or green or blue) uses the same power as full white.

Thanks Greg, excellent video, very clear and helpful

This was interesting and educational, thanks.

Brilliant Greg, this answered a load of questions I had on these. Perhaps when you review the Baldrick you could touch on where that redundant data wire connects? Also I think I read somewhere that they have a different RGB order that has to be set on the controller, or is it in xLights? Great info though and well explained; keep ‘em coming!

Great info greg 👍

[@dtvking]

Thanks Greg. Very interesting with how they work & the lower power aspect. All the best

Thanks for That Greg, Good luck with the new Chanel.

Great explanation, many thanks 😁

Great video, Greg!

Greg good report but could you tell me what is the voltage drop at the end of a 100 pxel strings and how many do you think you could run without PI at 100% and say 30%

[@davidrobertson1293]

Do you need to convert to 4 wire pigtails or does some magic happen so it still works with a 3 wire?

[@gregmacaree]

The backup data should be linked to ground at the start, it will be generated from the first pixel onwards.

[@pyrostillsy]

Nice one Greg, thanks for the review 👍

[@BlaineDuffield]

From what I understand, the second data can be connected to ground or the data channel. I checked with a few manufacturers and they aren't completely in agreement but I tried both orientations with a set of strips and it did not seem to matter.

Excellent video, Greg. I have been using 4 wire strip on my arches for the last 4 seasons and have all 4 wires connected to the F16 v3 and the outputs set to WS2815 pixels. Your video suggests there's no need to run 4 core cable back to the F16, just bond backup data to groung at the 1st pixel and I can leave all the outputs set to WS 2811. Is that right?

[@gregmacaree]

@@BlaineDuffieldthe data sheet for GS2808 shows Backup Data connected to ground at the start.
