Cycling to clear up cloudy USA lamps?

[Egnix]

A couple questions regarding cycling a USA lamp to clear up cloudiness:

First of all, is there something special about constant cycling or is it just the fact that the cloudiness goes away after several uses and constant cycling accomplishes that in a shorter period of time?  In other words: would there be an end result difference if you had the lamp on 21 times for 8 hours at a time over 2 weeks versus having the lamp on 21 times for 8 hours over 2 months?

If there is a difference, then what is the consensus on cycling times for clearing up a cloudy USA lamp?  I've seen everything from 4 hours on / 4 hours off to 8 hours on / 8 hours off, and that seems like a very big difference.

Cycling the lamp won't do much to clear it.

it may end better, but if you really want a clear lamp, the only option is to filter it.

But it won't harm it to cycle it few times before filter it.

Good luck!
