Clever LCD

50,000 hours. On average, our projectors run at just over 1000 hours a year. So based on this, we should expect a Clever LCD screen to last for 50 years? Well I certainly won't be around to know if that's the case.

I have posted a blog review of one of these. I will keep it updated after we have run them for a while.

Dont get me wrong i think they are the way forward but 50,000 life ? with a projector the lamp you now get around 5,000 hrs then no light so new lamp, with a screen you get a dimming image i think the usable image will be around 7 to 8 years, even casio and their "claimed" life of at first i think it was 30,000 hrs is now down to around 5 years (both use LED) (although the casio has a composite source NOT lampless like many claim). But its not just the light, its like a TV many other things can go wrong and to think your getting a 50 year screen is a bit naughty, why would they sell you a 50 product what will they sell you next time, a few years ago ( i may have the name wrong but) Osram brought out a lamp that never wears out but of course would not sell it to the public or it would end the company, they survive by you replacing equipment same as anyone else. So i think if you buy them with a believable usable life of around 6 to 8 years you will then be able to work out realistic coatings to see if its worth it to you.

Dont get me wrong i sell these screens and other much less expensive brands and i do promote them but with realistic expectations of their life, and its not the people quoting you who are wrong they are just reading spec. its the way it is interpreted using experience and knowledge of the components its built with.

No school would think it would last that long. A standard replacement cycle would have it replaced after about 10 years anyway, just through normal technology improvements.
