Color matching LEDs?
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?
About 5M each. The strips are consistent end to end across themselves, just not with each other.
Ah probably not voltage drop then. You can try the white balance correction - https://kno.wled.ge/features/cct/#white-balance-correction
Playing with it, that would deffinitley do it! I just have to figure out how to do it channel by channel.
Posting for posterity: Given that WLED now allows for layering of effects, I'm going to explore creating a custom effect to change hue/white to match the two strands/channels. Not sure when I'll get to it but leave the breadcrumb for future folk.
