Brain function can start declining 'as early as age 45'. Read more about sharing. The brain's ability to function can start to deteriorate as early as 45, suggests a study in the British Medical Journal. University College London researchers found a 3.6% decline in mental reasoning in women and men aged 45-49. They assessed the memory, vocabulary and comprehension skills of 7,000 men and women aged 45 to 70 over 10 years.
But if a Uhing drive has been correctly timed and it has the proper thrust setting, and it has been correctly sized by an Amacoil technical sales person, then it should run much longer than two years. We're talking maybe 10 years or more. Amacoil recommends that all repairs be sent to our facility in Aston, PA.
-- Carl, Boston, Massachusetts. Carl, it depends on your definition of very long.. But generally speaking, a LCD projector lamp should last between 2,000 and 3,000 hours of viewing. That holds true for a Home Theater lamp or a lamp for a DLP TV. Of course, that number can vary. Like any kind of bulb, it might go dead in fewer hours than that, or it could last even longer. But if you buy a brand-name bulb that's compatible with your projector, you should get at least 2,000 hours of viewing. Now, how long is that in real-time? To use myself as an example, I've had a Sony VW60 Home Theater Projector, which has a Sony VW60 bulb, for about four years and I watch it quite a bit. I've used my projector for more than 1,700 hours and I have not had to replace the bulb yet.
