Will subwoofer vibrations affect projector lamp life?

tacopacofo

The subwoofer vibrates the walls and ceiling where it is mounted.

Answer
Definitely. You should place the subwoofer at least one foot from the wall where the projector is mounted and atop a speaker stand which is 4-6 inches in height.

Good luck!

Answer
It's certainly on the longer end of the norm for a non-LED projector. Most high pressure lamps in projectors are rated for 2-4000 hrs of use (with longer life in "eco mode"). Some claim up to 5000 hrs. BUT lamp lifetime is quite variable depending on how the lamp is treated and how one defines lifetime (lamps can still work but be much dimmer ... does this count?). I wouldn't be surprised to find that some claims of long lifetime lamps are inflated by including the tail end of the life cycle that more reputable manufacturers don't count. .

For example, rapid on-off cycles on a projector will shorten life significantly, while leaving the lamp on continually may give much longer lifetime than turning off after use (although much of the "lifetime" would then be wasted).

LED lamps -- available on some pico projectors and starting to show up on full size models have much longer lifetimes (20,000 hrs and more).

Projector Lamp Light Life...??

gthtjtkt

Hi, I purchased a projector with a lamp life of 3000 hours. We use it about 10 hours a day, so approx. 10 months it should last.. i checked online, and the replacement lamp is $300!!! So I was wondering, what does it mean lamp life? Does it mean, after 3000 hours it won't work at all... or it'll work but not recommended to use because quality has just degraded? I can live with quality degration. Anyone know where to get cheap lamps.. the newer the projector, are the lamps cheaper? Or the older?

Answer
Usually it degrades and the picture starts getting dimmer and dimmer. Other times the bulb can literally explode inside that wire cage it's mounted in... rare, but it does happen.
You should be able to set your unit for an "extended life" setting for the bulb that reduces the intensity about 10-15%, but almost doubles the life expectancy. It should be an option on your setup menu... usually within the part where you reset the lamp timer.
Try www.purelandsupply.com or www.focusedtechnology.com for replacement units at a better price.

it doenst nedd a dvd player either

Answer
While you may find a projector on eBay or elsewhere close to your price range (and a refurbished InFocus 4805, as suggested, would be a good choice if you can actually find one), you should be aware of a few things first.

The lamp in a projector needs to be replaced every 2-3000 hrs, so if you use for video games 3-4 hrs/day, that means you will have to replace it in as little as 18 months. And it could be sooner if you are not careful to cool down the lamp prpoerly after each use, avoid quick on-off cycles and protect against power cuts (which can shorten lamp life by ~20%).

The reason I make a big deal out of this is that a new lamp costs $300-$450 (depending on projector model), and usually only has a 90 day warranty.

Furthermore, to get a good picture from a projector rated under about 1500 lumens the room will have to be dark (or at least quite dim), and you need to project onto a screen ($200 or more to buy, $50 or so to make ... if you are handy) or onto a blank white (or light grey) wall.

Finally, make sure any model you find can be table mounted at a distance your room will accommodate for a reasonable picture size (this is not standardized).

So, a projector is a great idea, but go into the purchase planning to spend at least $250-$300 for the projector, more for a screen, and $3-$400 for a lamp in a year or so (or recognize the projector is a throw-away when the lamp goes. If you are OK with that ... happy gaming.
