Testing WS2812B LEDs

WS2818B RGB LEDs under test.
The first section shows the LEDs set as white RGB(255,255,255), but with different supply voltages.
The second section shows the LEDs supplied at the rated 5V, but with different RGB levels: RGB(255,255,255), RGB(128,128,128), ... RGB(1,1,1)

Adjusting supply volts with RGB(255,255,255)...

Camera settings: ISO100, 1/250 f/11 AWB:Daylight

Adjusting RGB levels with 5V supply...

Camera settings: ISO100, 1/250 f/22 AWB:Daylight

"Built-in signal reshaping circuit, after wave reshaping to the next driver, ensure wave-form distortion not accumulate.

"Each pixel of the three primary color can achieve 256 brightness display, completed 16777216 color full color display, and scan frequency not less than 400Hz/s.

"Any two point the distance more than 5m transmission signal without any increase circuit.

"When the refresh rate is 30fps, cascade number are not less than 1024 points.

"Send data at speeds of 800Kbps.

"The color of the light were highly consistent, cost-effective..."
