If each LED runs at 20mA and 2.4V, then 1,500 LEDs consume 72 watts - which is easily created via bicycle. Even those that don't exercise regularly can generate 72 watts.
A string of regular Christmas lights takes 2.5V at 170mA, which would require 638 watts. Lance Armstrong can average 400W for hours at a time, and could drive 638 watts for a short period of time. Your average person would be hard pressed to light them dimly.

I wonder when they will invent how to stock energy, this would be great.
Imagine yourself pedaling in the morning before going to work. You make your exercise and make light for your house.
Would be cool.
Uh, I actually think it's a short form of Hydroelectric, and isn't really a Canadian term for anything.
