I'm led to beleive that the lamps get dimmer as they get older and you could run it beyond the reccommended hours but eventually.... the bulb explodes!

Projectors usually have a counter that counts down the number of hours. When you reach the limit it refuses to work until you change the bulb. Bulbs are not allowed to explode inside the projector.

?? No my ae100 which defiantly counts the hours used. I'm only going by what was said at the AVSales shootout last May where I'm sure Andrew said that bulb times could be stretched a little but could make a mess if they blow.

It's if they explode you notice. It's not inevitable, and somewhere on the setup menu you can reset the lamp hour meter. They do get dimmer, and they do make a helluva mess if they explode. It's curable but not worth the bother, do't stretch it too far! How far is too far? No idea, but I'm sure the manufacturers are cautious, wouldn't you be what with liability and a fat profit on the bulbs?

It's easy to run the AE-100 beyone it's default 2000/5000 bulb life limits, without even resetting the bulb timer.

Given as it's 5000, I don't think many would feel the need to however.

BTW, bulbs MAY explode. The manufacturers are just being cautious here - scaremongering to a degree.

IMO, the chances of a bulb exploding after it's useful life is only marginally higher that it exploding within it's design life.
