I have a CDXL 18-SD lamp running in a Christie 2210 that is currently at 1761 hours. I've ordered another lamp, but it's in transit. Should I be freaking out? I am freaking out.

My temperatures are all okay - Lamp exhaust is 50c, integrator is 56c

The manual for the 2210 says I should change the lamp at 1500 hrs, the warranty is for 1750, and the Christie site for the lamp says 2100...so, should I be freaking out?

Will freaking out change anything? Just go on, it is not likely that this bulb burst while the new one is in transit. I suggest for the future you always have a replacement on site. Do you ignite that bulb multiple times a day, or only once?

No, we basically ignite it once a day. I have a few old bulbs lying around that have 1750 on them, as well.
Yeah, I usually have another one here, but it's been a crazy month and it slipped my mind.

Don't freak out. I once had a bulb that I thought had a 1500-hour warranty, that turned out to have a 1000-hour. I didn't realize it until the thing was at 1450 hours. I was sort of freaking out especially when I went to change it, but we were fine.

I wouldn't freak out. Christie/Ushio lamps don't explode that often at all and many go way over warranty. Now if you were running other brands...well...

It has an estimated average life expectancy of 2100 hours and you get a "100%" warranty of 1750 hours. So, there's nothing to freak out about.

It's good that you're a bit worried though, it keeps you on the edge on those things and avoids possible mayhem if you continue to let it slip. [Wink]

As others pointed out, just keep the amount of ignites to a minimum and everything should just turn out fine. Take the usual precautions when changing it. Try not to freak out, a good quality bulb slightly over its warranty isn't much more dangerous than one slightly under.
