Powering a lot of individually addressable LEDs Answered
I have been toying with an idea for a while of making permanent holiday light fixtures with individually addressable LEDs. The problem I continually run up against is that these types of LEDs all run on 5v power, I believe because of the driver that controls them. They have high voltage AC strips, but they aren't addressable.
If I take Adafruit's "Dotstars" as an example, they require 60ma of power per led at full brightness. A typical holiday display may require up to 250 feet of lights. If those lights are spaced at a typical 2.75 in apart that's 1091 lights. This becomes 65455ma or 65.5 amps of power. That's a stupid amount of power required for some holiday lights.
Are there any high voltage individually addressable leds on the market? Is such a thing even possible? If not, is there some type of wallwart that might help me solve this problem in a safe less power hungry way?
