I mean, Is it OK to apply 220 volts across it? ROLF

And for the second part of your statement, we do not normally limit the current in a circuit (LED) in this case. We just apply appropriate voltage and the circuit (LED) draws current according to its internal resistance.

We ONLY limit the current where we think a short circuit can happen and cause fire, like in houses and offices and we use circuit breaker for that. Its like a fuse, which limit the current up to a certain level.
