[QUOTE="merryoncherry, post: 125687, member: 37249"] People who bought pixels 2 or more years ago are going to tell you something different than I will, as the designs and most common chips have changed! If you go order 12V pixels today (pixels made this year or last year), [B]odds are[/B] the batch of regulated pixels are going to be noticeably brighter and use at least twice as much power as the batch of resistor pixels. You'll run 100 regulated pixels per controller port without PI, and 200-300 resistor pixels per port without PI, so plan accordingly. (Of course, with PI, you can do all 500 on one port, still 40FPS, but you'll spend more time and money messing with this than the $150 for 500 pixels. Then again, maybe you like spending time on the hobby, and that'll be more fun for you.) You will not notice any color differences with any of them, nor will you notice any difference at the start / end of the strings, because they have constant current drivers in them. If you care about color fidelity, you might turn down the red and blue slightly for a warmer feel, and set the "gamma" to 2.6. I only have 1 data point on 5V pixels, without PI they pinked slightly at 100 pixels, but I just adjusted it in xLights and nobody noticed.

The title of our introductory lighting manual contains a three digit number. What is that number? Clue: Display basics forum
