recently I've been wondering how so many leds can be powered by a single supply.

For example, my christmas lights have 1000 white leds on them which are powered from the mains. They definatly arn't connected in series which would require ~3.3KV, so how are they powered if each one doesn't have any sort of resistor on them?
