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?

If you select over 1000 LED's then of yourse you also need power for 1000 LED's.
If you need over 1000 of them addressable you better get a good light effect computer on top of it.
What would be the point of having a HV LED light if each LED only needs a voltage of 2,5V at most?
Doing it this way means you need the extra electronics all included in the lights and of course the price jumps up.

Watts are power, not amps (P = A * V). Using your numbers, 65.5A @ 5V is ~327 watts, not a terribly large amount of power for over 1000 lights.
