I know there are some variables involved (brand of TV, settings, etc)...but I'm wondering if there's any known accurate figure?
I've seen it listed as 10,000 hours, as 10,000-15,000 hours, as 15,000 hours, as 10,000-20,000 hours, as 30,000 hours, and some even higher figures.
Is there any particular figure that comes from a reputable source?
Also, I'm wondering if the number varies depending on the size of the TV. For instance, I've heard some people say smaller CRTs tend to last longer. Would this hold true for the brightness as well?
