Bright LED Strip

UPDATE

I tested 4 different addressable strips for my Kitchen Lighting upgrade project.
The strips are (all are 16.4ft 300LEDs):

  • 5V WS2812b (very common strip)
  • 24V WS2811 (6 LEDs per pixel)
  • 12V WS2815b
  • 5V SK6812 RGBW

First 3 are about the same as far as brightness consideration.
And unfortunately for this specific project the brightness of the
above first 3 strips is not enough.

Last one (5V SK6812 RGBW) looks promising IF I can
control all 4 LEDs. Unfortunately this is not a case.
Event thought, in docs Pixelblaze/IO_Expander claims to be
compatible with SK6812 RGBW LEDs in reality it is not.
The details are in my second post:
