Using these NeoPixel Cool White LEDs is easy. First, if you're prototyping, solder them onto our 5050-size LED breakout PCBs for a breadboard-friendly setup. Then, connect them according to the wiring in our tutorial. You can control the brightness of each of the three cool - white dies. Just send a long string of data to control as many LEDs as you need. When it comes to power usage, check our tutorial for calculations. Remember, these LEDs use an 800 KHz protocol, so specific timing is required. Since the PWM is built - in, once you set the brightness, you don't need to keep talking to the strip. As for maintenance, keep them away from excessive heat and moisture. And when moving them around, be aware that the 400 Hz PWM rate might cause some pixelation. If you want smoother movement, consider using DotStars instead.
