    I was watching the Arsenal v Totenham game last night and all of a sudden there was a loud BANG and the picture went out.

    I took the projector down today and removed the lamp and as I suspected, it was the lamp that had exploded. I had to vacuum up the debris from the lamp enclosure before putting the new one in.

    I bought the projector in June 2006 and got 699 hours out of the lamp. Is that about the expected life span of a lamp ?

    I was suprised when I saw the picture after putting the new lamp in. It was so bright and colourful. It makes you realise how badly a lamp deteriorates over time.

    What projector was it?

    Lamp life expectanties differ from projector to projector, but 699 hours is really quite bad. Usually they're at least 1000 hours, most of them are 2000+.

    It was an Optoma Themescene HD72i.

    It's always been switched off properly apart from one time when there was a power failure.

    I have used bright mode at times in the past which I think reduces the lifespan of the lamp.

    They quote 2000 hours typical lamp life. Oh well, at least its an excuse to get a new and bright lamp in :D

    This can take 90% off the lamp life.

    That's a good point actually, which one did you get?

    I bought a few years ago but it was this one:

    http://www.amazon.co.uk/Belkin-Regulator-Pro-Silver-350VA/dp/B0002AFF30

    I think it was in the region of £40 when I got it. You don't need anything fancy or big, just something reliable and with enough battery to give you the minute you need to shut down safely. Most UPSs will run for loads longer than this e.g. 10-20 mins.

    As a bonus, if you do loose power you can use the UPS to power up your router and you can still surf the web for a while from your laptop!

    Really that seems a bit hard to believe!

    Damn... my RCD tripped twice a few weeks ago while the PJ was on. It's only got 350 hours on the clock as-well.

    UPS does sound like a good option.

    UPS sounds like a good idea. I've come across this one:-

    http://www.ebuyer.com/product/113907

    Seems like a good bet at a reasonable price £62. There's cheaper ones available but they all seem to have IEC sockets instead of standard mains sockets.

    Good point, I got around it by making up a cable from a kettle lead and a cable mount 3 pin mains socket. Probably cheaper and space saving.
