Depending on the quality of their design - and the quality of the components used in their manufacture - compact fluorescent light bulbs have rated lifetimes between 4,000 and 12,000 hours of "actual in-use time" whilst they are switched on.
These ratings are for use under ideal cooling conditions and the lifetimes can be greatly reduced if their miniature ballast circuits overheat,such as when the bulbs are used in fully enclosed and/or recessed lighting fixtures.
