Question to all those who run LCD projectors during video shows..

How often would you say you replace the bulb in your LCD projector? Where do you buy them at? Do you keep one on hand for backup purposes?

Any info about this would be great.. Thanks in advance!
 
Bulbman is a great source for lamps. Most projectors have an hour meter built in that tell you how much useable life is left in the lamp. Unless abused, you generally get a good warning. Projector lamps should be replaced when the warning comes up; waiting until they fail is asking for damage to the projector. I guess you could say a backup is a good idea! Our lamps last many years....I can't say for sure because we buy so few. Check your manual for what your lamp expectancy should be on your particular brand/model.
 
As soon as you see it dimming...replace it.
If the red light is flashing, replace it.

Don't move it while its on.
Let it cool down 30 minutes before moving it if possible.
Keep that bulb from vibrating in transport.


I had a 2000 hr. bulb go really dim at 675 hrs. Then out....

bulbman good, no bulbman bad.
 
I’ve been using LCD projectors since the early 90’s & I’ve yet to have to replace a lamp in any of my projectors. I brought one lamp as a backup for a projector a brought used & the backup lamp still sitting in my office. That projector I used for business, home, rentals, its been shipped on airlines to events & still haven’t clocked enough hours to replace the original lamp. Figure if the lamp has 2000 and you run the lamp to 1000 hrs that is 250 4 hr events. The new projectors have lamps going up to 6,000, I believe those are DLP projectors.

What I do is always carry a backup projector. If something does go wrong in the middle of an event the last thing you want to do is open up a projector. With a backup projector your back up in running as fast as you can get the second projector back in place. I’d say I’ve heard more stories of projectors not working after being dropped or banged around (and a backup lamp wouldn’t fix the problem) than lamps reaching their limits. One other thing would be to make sure you have good cases to protect the video in transport. If the warning does come on replace the lamp ASAP as I’ve been told lamps pass there limit can breakup in pieces inside the projector & you don’t want that.

I have NEVER replaced a lamp in a projector, as I have never keep one long enough to have to replace it. Personally, for the inflated cost of replacement lamps compared to continually dropping prices of new projectors, I will normally throw my projectors on ebay when I reach 50% of the lamp life, and buy myself new projectors. The net cost of the new projector is always less then the cost of relamping.
