![]() Has anyone else tried this combination, buck converters at the LEDs and 3 core extension leads for power+data? It is working a treat for meĪs I posted previously, I was able to get some great distances between pixels using this 5v strip. So power feed is easy, power supplies are all with the controllers and I don't care much about the voltage drop as it is regulated at the first LED by the buck converter, sweet! The feed from the controller box is 24V and my data/power feed cables are ordinary domestic 10amp 3 core extension leads. ![]() So each element has a buck converter right at the first LED. To avoid having huge thick power feed cables, which would cost a fortune and I would still get voltage drop problems, I purchased 20 x buck converters all LED's are 5V so voltage drop was my first challenge. I ran out of data leads at 40 meters and could not get any pixels to fault! I ran my fastest sequences for over 30 minutes at a time and could not see one pixel dropped anywhere!!! Wow, and I was so worried when everyone is talking about 3-6 meters. So I undertook a whole day of testing with both WS2811 pixels and WS2812B strips. I have just completed a major series of tests on my new display and one of the key features I wanted to check was to make sure everything works reliably, in particular, to make sure I don't get problems with data feed and determine the maximum distance between pixel nodes.
