Hey folks, sorry if this is the wrong place to ask, or if this is a super obvious question. I'm relatively new to this. I recently bought a WS2812B LED strip with around 300 LEDs, and when I set its color to plain white, it got white at the start of it but as it goes on it became more and more oran…

Welcome to the forum [image] cool_samurai_ninja: what's weird is that when i measured the voltage at the start, it was 5.03v and it gets down to 2.51v at the end There is nothing weird about that. A voltage drop is normal over a distance because of the resistance of the wire. Have you hear…

[image] UKHeliBob: There is nothing weird about that. I think the part that weirded me out was that it was still operational even with such low voltage, not the drop itself. [image] UKHeliBob: Have you heard of Ohms Law ? I did, but I didn't think that the wire's resistance would make…

You also have 300 leds open at safe max, and the WS chip per led drinking from the stream. Try running them half-bright just to see while you’re wired up? Adding power and ground points from thick wires or metal frame ground and a power bus bar as @UKHeliBob wrote about.

The issue you're seeing is called red-shift. Blue LEDs need a higher voltage than red LEDs, so the blue ones are the first ones to go dimmer when the voltage decreases along the strip. Powering the strip at both ends with two supplies (of half the size) is one way to counteract this. Running a thic…

How long is the strip? It's like the radial circuit commonly used for lighting in domestic situations. Typically it will be run in 1.0 to 1.5-mm2 solid copper, whereas power, sockets, are run in 2.5-mm2 arranged as a loop, the ring circuit. There's never any harm in oversizing cables other than co…

[image] GoForSmoke: Try running them half-bright just to see while you’re wired up? Yeah, it does seem to not be an issue when running on 20/255 brightness. I think that @Wawa is right, it is distorted because of the voltage drop. I'm going to try to inject power on multiple points along the…

Here is an explanation:

This will let you calculate the voltage drop yourself.
