Dual White Support

Hardware

Hi, I am looking to get some LEDs with adjustable white color temperature and am wondering if WLED will support something like https://www.aliexpress.com/item/32634891197.html

Thanks for your help!

Hi!

This is not currently supported sadly, but is on the list of feautures to add :slight_smile:
Once there is good color temperature support, PWM WW+CW strips will work well!

Thanks for the quick response! Is there a GitHub issue or thread where I can follow the work on color temperature support?

Hi @soberstadt,

yes you can look here: To-Do-List Aircoookie or here: To-Do-List Def3nder

Hi, may I suggest using HSI colour coordinate system? It’s very scalable in this regard

  • for RGB it’s straight-forward, hue is colour wheel angle, saturation adds remaining colour channel(s) and intensity dims all equally
  • for RGBW saturation fades between saturated colour and the white channel
  • for RGB-WW-CW a temperature value is added and it controls the WW-CW mix, the mix is then used instead of white channel for saturation control
  • and for WW-CW only, hue and saturation get dropped, temperature and intensity remain

this article explains it better than me, sans the WW-CW
