This is my first post, and I'm very new to the Hardware side of Making but I'm working on an led project and I need some advice. I want to use individually addressable leds, but my project is pretty large scale (think Christmas light show) and I want this to be done using consumer grade electronics. My concern is that I cannot find a high voltage low amp solution for my leds (Most I've seen run around 5v). I'm guessing this is because the micro-controllers require very low voltage before they burn out. I'm not super comfortable using high end high amp low voltage DC power supplies, and I was wondering if anyone knew of an alternative solution, or if I'm just wasting time looking. Thanks again, and please let me know if this is not the right place to pose this question or I'm not providing enough detail. I respect the stack exchange community and want to follow the rules.
The reason the LEDs you're finding are all <5V is simply because that is how LEDs are. Applications using LEDs at higher voltages are either chaining many together in series and/or incorporating special driver circuits. To get more of an answer than that, you're going need to provide more detail about your application.
