John, these Uninterruptible Power Supplies (UPS) are not that expensive, and will buy you enough time to power down. At $99.00 it's pretty cheap insurance to protect a $400.00 bulb. Shoot, my neighbour is even using a larger one on his sump pump.

Don't forget to check out the detailed specs and reviews.




Those are kind of hard to impliment when your projector is plugging into an outlet on the ceiling...

Touche. Once again, I put the cart before the horse. Seemed like a good idea at the time.......

That's why God made really thick extension cords.

Actually if you plan ahead, you can have "that" ceiling AC line routed to a location seperately where you have a UPS and/or power surge/conditioner. Mine is routed to my AV closet and then hooked to my Tripp Lite unit.

Well, I still have that option (somewhat). My ceiling in the basement is not yet finished and I am doing a drop ceiling anyway. I could easily stick a power supply up there (above in the ceiling) and run the PJ cord up to the power supply (the outlet would be in the ceiling aswell, out of view from the public).

Is it REALLY worth all the hastle of having surge protector on the PJ? Will it get damaged? Is it worth the $100 and then finding a place to put it up in the ceiling?

I am sure the new projectors these days have been built for numerous scenerios in power failure.

I guess I could email Sanyo!

I actually do not run the fan when powering off. In the 2 projectors over the years I cut power to the projector once I'm done. I let the bulb and components cool down on its own account without the use of fan blowing in high mode to cool the unit down. Years ago (maybe about 7 I think)an AVSer did a test with his 4 projectors at work that was used fairly often. On the 2 units that cut off power vs units that were powered down using fan the bulb life on the powered off units lasted much longer based on his observations. To this day each of the projectors I have owned each lasting for about 3+ yrs each have yet to change the bulb even with the high hours.

My thinking is that a bulb is super hot and it gets cooled down quickly. Do this many times the components ends up contracting and expanding too quicky and eventually creates cracks.

This is just my personal observation. I have yet to change the original bulbs that came with the unit. My dad X1 is past 3000 hrs and it as good as it was years ago,.

Interesting... so you're thinking the bulb might actually last LONGER if allowed to cool down at a slower rate.

I agree, this is interesting. My fan runs very quietly during operation to keep air circulating. I would think that if you just shut everything off, the heat would not be exhausted efficiently, similar to computers and/or servers.

sirquack: Computers are different. If CPU core temperature is not kept cooler than a certain limit the CPU will burn out.
bridgeman: Both my dad and the person who I sold my old infocus X1 has higher numbers and years with their first bulb than for instance my cousins X1 who has already changed the bulb once. I have told my dad and the guy I sold my X1 to cut powr off on the projector. There is still working fine.

Please note these are my personal observations and this is what I do for my setup and it works for me. I can not be responsible if you diminish the life of your bulb by using my methods.

Here is an interesting thread that disqualifies what I just mentioned.

http://forum.ecoustics.com/bbs/messages/2/176314.html

As I mentioned this works for me and I am going to stick by it. Its been almost 3 years without issues.
Sirquack drop me a message a year from now and see if yours and my unit is still all fine and dandy.
