A SECRET WEAPON FOR WHY IS MY PROJECTOR SCREEN GETTING DIMMER

I are already considering laser projectors for some time now, but what would seem off-putting to me, will be the quoted life expectancy.So if 50% decline at 20k several hours, 25% reduction at 10K hrs. Have you communicated with manufacturer engineers about this and does it range by manufacture or even model? Thanks.Jim, just as much as the LS12000
