To keep the image bright what would be a "reasonable" hours used before changing out the lamp? I can't recall how bright it used to be when new so I don't have anything to compare to but brightness is important b/c I watch many 3D movies. I don't use it terribly often, maybe 5-10 hours a week, if that.
