doing the math... you can have up to 28,000 red LEDs connected to a single outlet!

work:
red LED 1.9v x 20 ma = 38mw
outlet 110v x 10a = 1100W
1100/0.038 = 28947 LEDs

Should say on the packaging the lights were shipped in, right?

If these strands chain together using 110VAC (like traditional lights), I would expect the number to be fairly high given how much less power LEDs draw than traditional lights. If they use a separate power supply and you're chaining them together at the lower voltage, it's a question of how much power that supply was designed to provide.
