Color matching LEDs? (lemmy.world)

Hi!

I have crown molding LED lighting I'm doing. Its turning out well, but most rooms need multiple strips. Not a problem, but the two strips are slightly different color temp. Does anyone know if there's a setting I can play with to get them closer to alignment?

Setup notes:

addressable LED strips
24v with oversized power supply
driver running WLED
two channels on same driver (one strip per).
strip lengths are very close but not identical length

Are you injecting power at more than just the start of the line? That might solve the color issue. Voltage drop tends to make leds shift a little.

This depends on how long your runs are though, I would expect 24v to be more resistant

So I'm not doing power injection but I am running it off two separate channels of the same controller. I was hoping to avoid power injection :/

I'm surprised you can't tweak a baseline or something. Based on how it handles effects its got all the range it needs, its just a calibration thing.

Compare the beginning of the strip against the very end of it, are they the same color? How long are the runs?
